资本市场压力与企业策略性专利行为:卖空机制的视角

创新是一种不确定性高且周期长的投资活动,需要风险偏好更大、对失败容忍更高的市场环境,而资本市场具有筛选和发现创新型企业、有效分散创新风险的功能,因而对创新活动起着关键作用。然而,中国资本市场短期投资者比例高,融券交易成本高且交易不活跃,加上专利评价体系对不同质量的专利区分度较低,导致资本市场压力对创新活动没有发挥出信息机制和治理机制两种效应。相反,资本市场压力带来的负面信息表达渠道和管理层短期业绩压力,造成了中国专利申请中存在“重数量、轻质量”“重申请、轻维护”的企业策略性专利行为所衍生的“专利泡沫”问题。本文采用中国融资融券制度作为准自然实验,考察卖空机制对企业创新的影响效应和作用机理。研究发现,企业面临卖空压力时会更加积极地申请专利,但专利的申请质量有所下降,表现为专利授权率降低;专利结构有所恶化,最终授权数增加的主要是容易研发、授权快的实用新型专利和外观设计专利;专利得到授权后,企业放弃缴纳维持费用以终止专利权。这些策略性专利行为在短期内可以减少企业的卖空交易量,推高企业市值,但长期看对企业的业绩没有积极影响,是一种“创新假象”。卖空机制主要通过施压机制来影响企业创新,管理层业绩压力、外部监督压力、股价信息传递压力越大的企业,在面临卖空威慑时更有动力进行策略性专利行为。为促进企业创新向高质量发展,需要进一步完善融资融券制度和专利评价体系。     

How to analyze technology lifecycle from the perspective of patent characteristics? the cases of DVDs and hard drives

This study aims to analyze the technology lifecycle from the perspective of the dynamics of patent characteristics; the dynamics of patent characteristics are proposed as an approach for characterizing technology lifecycle in this study. DVD and hard drive technologies, which have already experienced their complete technology lifecycles, were selected for analyzing their patent characteristics as a function of the different stages of their technology lifecycles to thus obtain the objective of this research. The results obtained in this study provide a channel to assess the nature of firms’ innovation strategies along technology lifecycles. It can be observed that (1) patents attempt to cite more prior patent or non-patent references at the latter stages to find more technological or scientific sources that can contribute to technological innovation, (2) most litigated patents are granted in the Growth stage, so it is expected that patents in the Growth stage should be more important and, thus, more relevant to dominant design than the patents granted in other stages.     

Declared essential patents and average total R&D expenditures per patent family

The sharp increase in SEP declarations and declaring firms emphasizes the necessity for understanding firms’ innovation investment behavior in standardization. This paper empirically investigates whether declared standard-essential patents (SEPs) and the declaring firm’s business model (operationalized as a firm’s location in the value chain) are associated with a firm’s innovation investment behavior. To this end, we measure firms’ innovation investment behavior through average total research and development (R&D) expenditures per filed patent family for publicly listed firms from 1999 to 2018. Our sample mainly includes major SEP family declarants. We rely on a binary business model taxonomy differentiating upstream and downstream firms. Within that setting, total R&D expenditures rise with increasing fragmentation of declared SEP families, suggesting that firms adjust their R&D investments to declaration developments in standard-setting organizations (SSOs). We also show that upstream firms have significantly lower total R&D expenditures than downstream firms, which could indicate structural differences in their intellectual property (IP) and R&D management processes. Our results can help SSOs and regulators better understand firms’ innovation investment behavior.     

Do leading or lagging firms learn more from exporting?

An interesting theoretical debate arises when considering firm heterogeneity in learning from exporting. One perspective intimates that technologically lagging firms stand to benefit more from exporting because exposure to technological knowledge in foreign markets allows these firms to close the gap with their more technologically endowed counterparts. A contrasting perspective posits that technologically superior firms benefit more from exporting since these firms are better equipped to translate knowledge acquired in foreign markets into innovation. Using a sample of 1,744 Spanish manufacturing firms from 1990–1997, this study empirically investigates how exporting differentially influences the patent output of technologically leading versus technologically lagging firms. We find that exporting is associated with the ex post increase in innovative productivity for both technologically leading and lagging firms. However, subsequent to exporting, technologically leading firms apply for more patents than technologically lagging firms. Copyright © 2010 John Wiley & Sons, Ltd.     

Innovating standards through informal consortia: The case of wireless telecommunications

We empirically examine the effects of industry consortia on the coordination of innovation strategies of the members. Our analyses utilize membership data from 32 consortia in wireless telecommunication technology subfields from 2000 to 2005 and prior art citations in standard-essential patents. We find that connections among firms in informal and technically-oriented consortia significantly increase the likelihood that firms cite each other's patents in subsequent patents essential for the UMTS wireless telecommunication standard. Inventions that are likely to become part of the UMTS system tend to build on inventions by firm peers who were members of the same consortia, controlling for patent or firm fixed effects, technology class, and other characteristics. Consortia may enhance productivity of invention and increase the incentives to invest in R&D by internalizing potential externalities. They may also enhance efficiency of standardization by facilitating the interaction of committee and market processes. Consortia thus structure and constrain the process of innovating standardized technologies. This is problematic if consortia are not truly accessible for all the relevant parties. Policymakers thus need to balance these effects. For managers, the results show that participation in a variety of technical consortia enables influencing peers' innovation strategies related to compatibility standards.     

Endogenous Network Formation in Patent Contests And Its Role as A Barrier to Entry

In a setting of R&D competition, we study how collaboration affects strategic decisions during a patent contest, and how the latter influences the collaboration network structures the firms can form. We use an all pay auction approach to endogenize both network formation and R&D intensities, and to take heterogeneous and private valuations for patents into account. We find that the complete network is not always the only pairwise stable one. The other stable networks have the realistic property that some firms drop out of the contest. Thus, ‘weak’ cooperation can serve as a barrier to entry on the market for innovation.     

Inventor bricolage and firm technology research and development

We examine the conditions around firm use of 'inventor bricolage,' or the reconstruction of technological capabilities through reallocation of extant individual inventors to address new opportunities embodied in patents. Empirically, we examine the dynamics of both firm and individual patenting activity in publicly traded Life Science Diagnostic firms to explore how inventor bricolage is related to firms' existing research and development (R&D) capabilities and firms' acquisition of external capabilities through merger and acquisition (M&A) activities. Evidence at the firm level suggests that breadth of inventors' human capital and collaboration with co-researchers with relevant experience is positively related to inventor bricolage. At the inventor level, the fewer patents an inventor has, the broader the individual's prior patent portfolio, and the more co-researchers with relevant experience, the more likely inventors will patent in a new area. M&A does not appear to have an impact on the utilization of existing human capital. Our findings suggest that R&D managers should assign inventors with less assimilative capacity and more creative capacity in teams where there is relevant experience in order to promote inventor bricolage.     

Scope versus speed: Team diversity,leader experience,and patenting outcomes for firms

Research Summary: How does the organization of patenting activity affect a firm's patenting outcomes? We investigate how the composition of patenting teams relates to both the scope of their patent applications and the speed with which their patents are approved, by examining the main effects of team members’ intra‐organizational diversity (based on affiliations with formal organizational units and informal organizational communities) and the moderating effects of team leader experience. We test our moderated mediation model in a sample of 121 teams that filed patents in a Fortune 50 company's India R&D center between 2005 and 2015, using proprietary employee data combined with newly released micro‐data from the U.S Patent and Trademark Office (USPTO). Our findings illuminate the micro‐foundations of innovation in firms by highlighting a trade‐off between organizing patenting activity to maximize scope versus speed. Managerial Summary: Patenting is an important strategic tool that firms can use to protect and create value from their innovations. A firm can benefit from filing a patent application that gives it a wider possible set of claims related to an innovation. It can also benefit from faster approval of a patent application by the Patent Office. However, our study shows that there is a trade‐off between patent application scope and patent approval speed, which creates tensions for the organization of patenting activities inside firms. In particular, we find that the diversity of a patenting team is positively related to patent scope but negatively related to patenting speed, and that these relationships vary with the experience of the team leader.     

A Longitudinal Study of the Impact of R&D,Patents, and Product Innovation on Firm Performance

Because of increasing levels of competition and decreasing product life cycles, a firm's ability to generate a continuous stream of innovations may be more important than ever in allowing a firm to improve profitability and maintain competitive advantage This paper investigates several issues that are central to an examination of the innovation productivity in a firm. First, the relationship between a firm's commitment to research and development and its innovative outcomes is examined. Two innovative outcomes are analyzed: (1) invention, which focuses on the development of new ideas; and (2) innovation, the development of commercially viable products or services from creative ideas. Invention is measured by the number of patents granted, and innovation is assessed by the number of new product announcements. Second, because many inventions ultimately result in marketable innovations and because patents may provide protection for new products, the relationship between patents and product announcements is also investigated. Finally, the ability of a firm to benefit from its inventions and innovations is studied by examining their separate effects on firm performance, measured as return on assets (ROA) and sales growth. Drawing from a sample of 272 firms in 35 industries over 19 years, the results from a model of simultaneous equations provided support for some of the hypotheses, but several other surprising findings were found. As expected, R&D spending was positively related to patents. This finding is consistent with others who argue that internal research capabilities, particularly those with a strong basic research component, is key to enabling a firm to generate creative outputs. More surprising was the finding of increasing returns to scale to R&D spending. While this contradicts much of the existing research, it is consistent with economic arguments for the advantages of scale in innovation. Also interesting is the finding that, while a significant curvilinear relationship exists between R&D spending and product announcements, it is not the predicted inverse‐U but instead a U‐shaped relationship. Consistent with previous work, product announcements were found to be positively related to both performance measures. A negative relationship was found between patents and both ROA and sales growth. While these findings were unexpected, they are intriguing and call into question the value of patents as protection mechanisms. In addition, these results may be resulting from the rise of strategic patenting, where an increasing number of firms are using patents as strategic weapons. As expected, a positive relationship was found between patents and new product announcements.     

Strategic determinants of decisions not to settle patent litigation

Settlement outcomes in patent litigation are modeled as resulting from strategies pursued by firms with their patented technologies. Hypotheses are derived for two types of influences: the use of patents as isolating mechanisms to protect valuable strategic stakes, and their ‘defensive’ role in obtaining access to external technologies through mutual hold‐up. Parameter estimates from a sample selection probit model provide support for the strategic stakes hypotheses, while the evidence for mutual hold‐up is inconclusive. Interindustry comparisons show that nonsettlement of patent suits in both research medicines and computers is increased by strategic stakes and, in addition, mutual hold‐up appears to play an important role in computer patent suits.

The Effect of Family Involvement on Innovation Outcomes: The Moderating Role of Board Social Capital

Innovation is an essential and yet puzzling part of family firms’ strategic focus. While family firms are generally characterized as conservative regarding their research and development (R&D) activities, researchers have recently argued that family firms can still achieve innovation-based competitive advantages. Seeking to understand the link between family influence and the outcomes of innovation, we suggest that it is necessary not only to observe the depth of family involvement, but also to differentiate between technological inventions and market innovations. We further posit that the board members’ social capital constitutes an important contingency for this link. We, therefore, investigate the relationship between family involvement and two different outcomes: the number of the firm’s inventions and the market relevance of innovations. Our analysis of S&P 500 firms comprises 1.85 million patents and manual evaluations of 1774 product announcements. The results of our estimations suggest that family involvement is negatively related to the number of inventions and positively related to the market relevance of innovations. They further show that internal and external board social capital moderate the relationship between family involvement and the number of inventions. This study adds to the discussion about family firm innovation by using socioemotional wealth to explain heterogeneity in innovation patterns and revealing that relational resources derived from board social capital are crucial boundary conditions for families’ influence on technological inventions. Taken together, it works toward a more holistic view of innovation in family-influenced firms.     

How public policy can stimulate the capabilities of firms to innovate in a traditional industry through academic engagement: the case of the Swedish food industry

This paper shows how public policy can stimulate innovation in low- and medium-technology industries, by connecting firms and universities through collaborative scientific research. A conceptual framework proposes that collaborative research between universities and firms may result in tangible innovative outcomes, such as new or improved products or processes, and intangible outcomes that strengthen firms’ internal capabilities and thereby indirectly increase their innovativeness. Findings are presented from a case study of a Swedish public policy stimulating the development of firm capabilities for innovation, through collaborative research projects connecting universities and firms in the food industry between 1998 and 2006. In line with the conceptual framework, the analysis distinguishes between (i) direct outcomes, such as new products; and (ii) indirect outcomes in the form of the development of firms’ capabilities to innovate. Based on this analysis, the initial conceptual framework is expanded to indicate how policy can stimulate the development of firms’ capabilities.     

Network location and learning: the influence of network resources and firm capabilities on alliance formation

This paper presents a dynamic, firm‐level study of the role of network resources in determining alliance formation. Such resources inhere not so much within the firm but reside in the interfirm networks in which firms are placed. Data from extensive fieldwork show that by influencing the extent to which firms have access to information about potential partners, such resources are an important catalyst for new alliances, especially because alliances entail considerable hazards. This study also assesses the importance of firms’ capabilities with alliance formation and material resources as determinants of their alliance decisions. I test this dynamic framework and its hypotheses about the role of time‐varying network resources and firm capabilities with comprehensive longitudinal multi‐industry data on the formation of strategic alliances by a panel of firms between 1970 and 1989. The results confirm field observations that accumulated network resources arising from firm participation in the network of accumulated prior alliances are influential in firms’ decisions to enter into new alliances. This study highlights the importance of network resources that firms derive from their embeddedness in networks for explaining their strategic behavior. Copyright © 1999 John Wiley & Sons, Ltd.     

When do strategic alliances inhibit innovation by firms? Evidence from patent pools in the global optical disc industry

Research and development (R&D) consortia are specialized strategic alliances that shape the direction and scope of firm innovation activities. Little research exists on the performance consequences of participating in R&D consortia. We study the effect of patent pools, a unique form of R&D consortia, on firm performance in innovation. While prior research on alliances generally implies that patent pools enhance firm innovation, our study finds the opposite. Analyzing data on systemic innovation in the global optical disc industry, we find that patent pool formation substantially and significantly decreases both the quantity and quality of patents subsequently generated by licensors and licensees relative to the patenting activity of nonparticipants. Our empirical findings suggest that patent pools actually inhibit, rather than enhance, systemic innovation by participating firms. Copyright © 2011 John Wiley & Sons, Ltd.     

Does international research and development increase patent output? An analysis of Japanese pharmaceutical firms

Internationalizing research and development is often advocated as a strategy for fostering the development of technological capabilities. Although firms conduct international R&D to tap into knowledge bases that reside in foreign countries, we argue that in order to benefit from international R&D investments firms must already possess research capabilities in underlying or complementary technologies. We examine the international R&D expansion activities, research capabilities, and patent output of 65 Japanese pharmaceutical firms from 1980 to 1991. We find that firms benefit from international R&D only when they possess existing research capabilities in the underlying technologies. In addition to refining our understanding of when international R&D enhances firm innovation, our results integrate asset‐seeking and asset‐based theories of foreign direct investment. Internationalizing R&D to tap into foreign knowledge bases is consistent with asset‐seeking theories of foreign direct investment, while the contingent nature by which firms benefit from international R&D is consistent with asset‐based theories of foreign direct investment and the notion of absorptive capacity.

Patent management in entrepreneurial SMEs: a literature review and an empirical study of innovation appropriation,patent propensity,and motives

Managers make a number of strategic choices when trying to capture returns from innovation investments, including what appropriation strategy to use and whether or not to patent, strategic choices that depend among other things on firm size. Previous literature, being reviewed in this paper, shows that the patent propensity is lower in small and medium‐sized enterprises (SMEs) than in large firms and that patenting as means for appropriation is of less importance among SMEs. Chief executive officers (CEOs) and/or research and development (R&D) managers of 26 entrepreneurial SMEs have been interviewed to explain these differences and to provide insight on how patenting is used in SMEs. The patent competence was low among the studied SMEs, and internal patent resources were found to be important for effective and efficient use of the patent system, for application as well as monitoring and enforcement. While of limited perceived importance for protecting inventions in entrepreneurial SMEs, patents were used to attract customers and venture capital, which is of utmost importance for the survival and growth of these firms. Thus, patenting has an important role to play even in firms where the protective function of patents is secondary.     

The adoption of radical manufacturing technologies and firm survival

The emergence of dramatically innovative, or radical, new manufacturing technologies can force pivotal and life‐threatening decisions for industry competitors. These technologies can represent a huge cost for adopting firms, but may also offer the chance to achieve competitive advantage through superior manufacturing. While prior research has considered a range of production process decisions (e.g., JIT, mass customization) and outcomes for end‐product technologies, little attention has been given to adoption decisions relative to core manufacturing technologies. This study examines an industry's adoption of major manufacturing technologies over several decades and demonstrates that two groups of contingencies related to adoption (e.g., timing and cumulative effects) have a significant impact on firm performance. Based on a sample of over 1,000 firms, the results provide insights into the effects of adoption timing and ‘manufacturing technology bundles’ on firm survival. We also find that adoption of manufacturing technologies prior to the inflection point of the estimated Bass diffusion curve for each technology leads to significant reduction in firm mortality. Thus, we are able to demonstrate the ability of the Bass model to predict the survival outcomes of firms facing manufacturing technology adoption decisions. The strategic implications of these pivotal decisions are considered. Copyright © 2008 John Wiley & Sons, Ltd.     

An inquiry on dimensions of external technology search and their influence on technological innovations: evidence from Chinese firms

A central part of technological innovation for industrial firms involves search for new external knowledge. A well‐established stream of literature on firms' external knowledge search has demonstrated that firms investing in broader search may have a great ability to innovate. In this paper, we explore the influences of technology search on firms' technological innovation performance along three distinctive dimensions: technical, geographic, and temporal dimensions, using a unique panel data set containing information on Chinese firms that were active in technology in‐licensing and patenting during the period 2000–2009. Our findings reveal that Chinese firms' technological innovation performances are related to external technology search in quite different ways from the ones suggested in the extant literature using evidence from developed countries. We find that Chinese firms searching ‘locally’ along the technical dimension have better technological innovation performance than those searching ‘distantly’. However, when a Chinese firm in‐license relatively old (mature) technologies or those from geographically nearby areas, it will be less bounded to searching familiar technical knowledge.     

Application and performance impact of stage–gate systems – the role services in the firm’s business focus

Although service innovation is important, knowledge of new product and service development, including the positive effect of stage‐and‐gate‐type systems, has been derived almost exclusively from studies in the manufacturing sector. In the present paper, we address two important questions: How do differences in the firm’s business focus, which describes whether a firm puts more emphasis on products or services in its business activities, influence the usage of such formal innovation processes? Is stage‐and‐gate‐type systems’ impact on innovation program performance contingent on the firm’s business focus? Unlike previous studies, we not only differentiate service and manufacturing by industry classification codes but also apply a continuous measure to take into account the blurring of boundaries between the manufacturing and service businesses. Based on a comprehensive discussion of service‐specific characteristics and their implications for innovation management and using a cross‐industry, multi‐informant sample of innovation programs from 272 firms with 1,985 informants, we find empirical support for firms with a stronger focus on the service business being less likely to use stage‐and‐gate‐type systems. Furthermore, the use of stage‐and‐gate‐type systems fosters innovation program performance, and this effect becomes stronger as the business focus shifts toward services. This result implies that service‐based firms can benefit from stage‐and‐gate‐type systems to a greater extent than product‐based firms. Our research also demonstrates the gap between the desired level of innovation process formalization and its current usage in practice, especially for firms with a dominating service business.     

How do dynamic capabilities transform external technologies into firms’ renewed technological resources? – A mediation model

How externally acquired resources may become valuable, rare, hard-to-imitate, and non-substitute resource bundles through the development of dynamic capabilities? This study proposes and tests a mediation model of how firms’ internal technological diversification and R&D, as two distinctive microfoundations of dynamic technological capabilities, mediate the relationship between external technology breadth and firms’ technological innovation performance, based on the resource-based view and dynamic capability view. Using a sample of listed Chinese licensee firms, we find that firms must broadly explore external technologies to ignite the dynamism in internal technological diversity and in-house R&D, which play their crucial roles differently to transform and reconfigure firms’ technological resources.
