贸易成本、本地关联与产业集群迁移

本文着重分析在劳动力成本上升和人民币升值的背景下,沿海产业集群迁移的影响因素、可能的迁移倾向和应对策略。由于产业集群的本地关联性和对国际市场的依赖程度不同,生产和贸易成本上升对这些集群区位再选择的影响也不同。由跨国公司主导的一些高技术产业加工贸易集群向沿海中小城市或低成本国家迁移的倾向会越来越明显;而数量众多的传统产业集群,随着出口增长率的下降和内需的提升,向中西部地区扩散或迁移的速度将会加快。东部沿海地区应积极扩散一些已丧失优势的劳动密集型产业,同时抓住世界服务业转移的机会实现产业升级;中西部地区要着力创造有利于承接沿海产业转移的软硬环境,尤其是降低物流成本和交易成本。开展区域合作,减少企业迁移的不确定性,是促进产业理性转移和区域协调发展不可忽视的环节。     

高新技术产业集群中的社会资本效应分析

高新技术产业集群中社会资本的效应很大,主要体现在以下几个方面：影响高新技术产业集群的位置、发展速度和信息交流,促进集群内经济主体的合作;从契约角度来看,可以有效解决高新技术企业技术创新网络中契约缺口问题;有助于高新技术产业集群由萌芽阶段向初级阶段发展,并保证产业群由初级阶段进化到高级阶段;有助于促进高新技术产业集群实现知识的转移、流动和创造;有助于促进高新技术产业集群内企业间的集体学习;有助于高新技术产业风险投资基地的建立;有助于提高高新技术产业集群内企业创新效率;使高新技术产业集群内技术创新扩散更加迅速;激励高新技术产业集群内人才创新;等等。     

基于模块化的银行卡产业价值创新研究：从价值链到价值群

以往关于模块化的应用研究主要集中于制造业,本文是模块化理论在金融服务业应用研究的一次尝试。本文认为,银行卡产业模块化的价值创新机理就在于实现了从价值链向价值群的价值创新系统转变。我国银行卡产业模块化价值创新应该从三个方面着手:一是在产品模块化创新层面,着重银行卡产品设计规则参与、产品创新和服务标准化;二是在企业模块化再造层面,着重银行卡业务组件模块化和组织管理模块化;三是在生产网络模块化层面,着重外包策略和网络联盟在实现模块价值创新中的重要作用。     

Managing innovation networks: Exploratory evidence from ICT, biotechnology and nanotechnology networks

This study examines the management of innovation networks which has enjoyed increased recognition in the marketing literature due to its growing prominence and relevance. By testing a causal model relating network factors to outcomes, the study contributes to theory development on managing innovation at the net level of analysis. Consequently, it contributes to the respective marketing literatures on new product development, open innovation, industrial marketing and its emerging network management sub-stream. It also offers a methodological contribution as respondents include key players from businesses, government agencies, research organizations and universities rather than from only one focal organization as studies in extant literature have predominantly done. Findings are based on 219 responses from Australian high technology networks, namely, information and communications technology and biotechnology/nanotechnology. The study offers valuable implications for marketing managers involved in new product development and innovation concerning strategies for managing their inter-organizational innovation initiatives effectively.     

试论产业集群租金与产业集群演进

本文提出了产业集群租金的概念,并将产业集群租金按源泉分为产业租金、地理租金和组织租金。本文认为,产业集群起因于生产要素对产业集群租金的追逐,租金的耗散导致产业集群的衰败。随着产业集群租金的主要来源由产业租金、地理租金向组织租金演变,产业集群从非正式产业集群向有组织的产业集群、创新型产业集群演进。     

Complex adaptive system mechanisms,adaptive management practices,and firm product innovativeness

As a fascinating concept, the mechanisms of complex adaptive system (CAS) attracted many researchers from a variety of disciplines. Nevertheless, how the mechanism‐related variables, such as strategic resonance, accreting nodes, pattern forming, and catalytic behavior of organization, impact the firm product innovativeness is rarely addressed empirically in the new product development (NPD) literature. Also, there exist limited studies on the antecedents of the mechanisms of CAS in the NPD literature. In this respect, we identified and operationalized the adaptive management practices, which involve bonding, nonlinear, and attractor behaviors of management, as antecedents of mechanisms and firm product innovativeness. By studying 235 firms, we found that (1) strategic resonance and accreting nodes are positively related to firm product innovativeness, (2) bonding, nonlinear, and attractor behaviors of management positively influence the mechanism variables, and (3) market and technology turbulence impact the adaptive management practices. We also found that mechanisms of CAS partially mediate the relationship between adaptive management practices and firm product innovativeness.     

The evolution of firm networks: from emergence to early growth of the firm

This paper addresses whether cohesive networks of socially embedded ties or sparse networks rich in structural holes are more conducive to the success of new firms. We propose that the networks of emerging firms evolve in order to adapt to the firm's changing resource needs and resource challenges. As firms emerge, their networks consist primarily of socially embedded ties drawn from dense, cohesive sets of connections. We label these networks identity based. As firms move into the early growth stage, their networks evolve toward more ties based on a calculation of economic costs and benefits. This shift from identity-based to more calculative networks is manifested in the evolution of the firm networks: (1) from primarily socially embedded ties to a balance of embedded and arm's-length relations; (2) from networks that emphasize cohesion to those that exploit structural holes; and (3) from a more path-dependent to a more intentionally managed network. Thus, this paper suggests that both cohesive and sparse networks are conducive to firm performance when they are aligned with and address firms' evolving resource challenges.

Knowledge,firm boundaries,and innovation: Mitigating the incumbent's curse during radical technological change

We explore the relationship between a firm's organization and its ability to face a radical technological change. We suggest that, during such a change, the presence of both in‐house upstream knowledge and downstream market linkages, within a firm's boundary, has its advantages. We test our predictions in the context of the robotics industry where manufacturers of mechanically controlled “brawny” robots, which were valued mainly for their payload capacity, faced the advent of electrically controlled “brainy” robots that emphasized accuracy and repeatability. We find that “preadapted” firms—the ones with prior relevant technological knowledge and with access to internal users of “brainy” robots—were the innovation leaders in the emerging new technology but were laggards in the old technology.

Alliance networks and firm performance: The impact of repeated partnerships

A phenomenon that has become the focus of recent research on interorganizational alliance network growth is that firms often enter into repeated relationships with prior partners. The implications of this tendency on corporate performance, however, are not well understood. From transaction cost and network perspectives, I test competing hypotheses on a large sample of multinational corporations. My results indicate clearly that firms not only often do enter into repeated equity‐based partnerships but also that those with a greater propensity to do so experience inferior economic performance. Further, statistical tests indicate that the negative effect of repeated partnerships on performance is particularly strong in environments of greater technological uncertainty.

Designing alliance networks: the influence of network position,environmental change,and strategy on firm performance

Alliance networks are strategic decisions involving trade‐offs between two stylized structural design choices: prominent and entrepreneurial. Prominent alliance networks emphasize benefits arising out of multiple access and affiliation to other prominent firms in the network. An entrepreneurial position, on the other hand, emphasizes brokerage and diversity benefits arising out of access to nonredundant and diverse information. We demonstrate that the performance benefits of each type of alliance network are contingent on environmental change and strategy, and are thus time dependent. Following an environmental change event in the steel industry, alliance networks that were more entrepreneurial performed better, while those that were more prominent suffered performance decline. However, when the change was radical, both types of alliance networks were negatively related to performance. We suggest that following a radical change, industry alliance networks may not have the requisite information necessary for quick and effective strategic responses. Firms pursuing an analyzer strategy performed better when emphasizing a prominent, and to a lesser extent, entrepreneurial alliance network. However, firms that develop an alliance network high on both prominent and entrepreneurial structural positions had lower relative performance. Our results indicate the need for managers to assess their alliance portfolio over time and redesign it based on environmental and strategic contingencies.

Knowledge Spillovers,Mergers and Public Policy in Economic Clusters

This paper investigates how market concentration affects research activity in an economic cluster. The firms in the cluster play a two-stage game. In the first stage the firms choose whether or not to engage in costly research that generates technological improvements that spill over to the other firms in the cluster. The more firms engaged in research the richer or more profitable is the pool of knowledge that spills over. In the second stage after the knowledge spillovers have occurred, firms compete in quantities. We solve for the symmetric mixed strategy equilibrium to the first stage of the game, and find that too low a degree of concentration in the cluster will destroy firms' incentives to undertake research and so the cluster risks stagnation. We explore whether a merger can stimulate research activity by increasing concentration in the cluster. Finally, we consider a public policy response to stagnation and analyze whether a direct public subsidy to stimulate research is preferable to a self-financing arrangement.     

Appropriability,preemption, and firm performance

The impact of strategies used to appropriate innovation rents on firm performance is analyzed using a sample of U.S. public manufacturing firms. Stronger appropriability at the firm level, achieved through patent protection or the ownership of specialized complementary assets, leads to superior economic performance, as measured by the stock market valuation of a firm's R& D assets. Among commonly used ‘nonconventional’ patent strategies, preemptive patenting allows incumbents to strengthen their market power. Consistent with theory, such effect is higher for incumbents with higher ex ante market power and facing a higher threat of entry, and lower when R& D competition is characterized by the discovery of drastic innovations.

Pipes,pools, and filters: How collaboration networks affect innovative performance

Research summary : Innovation requires inventors to have both new knowledge and the ability to combine and configure knowledge (i.e., combinatory knowledge), and such knowledge may flow through networks. We argue that both combinatory knowledge and new knowledge are accessed through collaboration networks, but that inventors' abilities to access such knowledge depends on its location in the network. Combinatory knowledge transfers from direct contacts, but not easily from indirect contacts. In contrast, new knowledge transfers from both direct and indirect contacts, but is far more likely to be new and useful when it comes from indirect contacts. Exploring knowledge flows in 69,476 patents and 89,930 unique inventors reveals evidence that combinatory knowledge from direct contacts and new knowledge from indirect contacts significantly affects innovative performance. Managerial summary : Inventors often combine ideas to create innovations. To do this, they need ideas to combine and they need the ability to combine those ideas. Inventors can get ideas to combine as well as the ability to combine ideas through prior co‐workers. Prior co‐workers can share ideas that may be relevant for the inventor's project and can tell the inventor about other things that other people are working on, especially people the inventor may not know. This can help inventors easily learn about ideas from friends‐of‐friends. The ability to combine ideas, however, is much harder to pass on. Prior co‐workers must carefully work with the inventor to teach him or her the complex processes of combining ideas. This means that it is very hard to learn how to combine knowledge from a friend‐of‐a‐friend, but it may be possible to learn from prior co‐workers. We explore this phenomenon in the social relationships of software inventors. Copyright © 2015 John Wiley & Sons, Ltd.     

A multilevel framework of firm boundaries: firm characteristics,dyadic differences,and network attributes

Extending prior firm boundary research that tends to focus on economic explanations and rely on atomistic assumptions, we propose a multilevel framework by bridging the resource‐based view and the social network perspective, with their respective emphases on the importance of firms' internal resource endowments and external resource opportunities. Specifically, we argue that firms' boundary choices can be better understood by considering the tension between the need for external resources and the need for risk controls, affected by internal and external resource factors at three important levels: firm characteristics, dyadic differences, and network attributes. We also explore firms' boundary choices under two conditions: whether to initiate external relationships (non‐partnering vs. partnering) and whether to pursue either alliances or acquisitions if external relationships are needed. Our analyses of the United States computer industry over a nine‐year span largely support our theoretical framework and demonstrate the importance of unique factors at and across individual, dyadic, and network levels in understanding firms' boundary choices.

企业规模、规模经济与产业集群

企业规模问题一直存在着截然相反的观点和主张,造成冲突的原因在于“企业规模”是一个各取所需的含混的概念。具有经济学意义的企业规模应该从两个相互正交的维度上———企业的横向规模和纵向规模———来度量。规模经济来自于横向规模的扩张,而纵向规模的扩张可能会带来规模不经济。产业集群是观察企业横向、纵向规模一个好的样本。区分企业规模的不同性质,将会使与规模经济相关的理论研究出现明晰的路径。
