The tradeoff between firm size and diversity in the pursuit of technological progress

Conclusion Our analysis lends support to both sides of the debate concerning the optimal firm size for achieving technical advance. It provides a basis for why industries composed of many small firms will tend to exhibit greater diversity in the approaches to innovation pursued, and why greater diversity will contribute to more rapid technological change. It also provides a basis for why industries populated by larger firms will achieve a more rapid rate of technical advance on the approaches to innovation that are pursued. These arguments together suggest that a tradeoff exists between the appropriability advantage of large size and the advantages of diversity that accrue from numerous small firms. Our analysis has been more appreciative than rigorous and, indeed, often explicity speculative. While we attempted to raise important questions, our framework requires more structuring before we can be confident about any of our conclusions. Even in its inchoate form, however, our analysis demonstrates that much needs to be done before the current debate about firm size can seriously inform policy. If we accept the plausibility of our basic framework, it focuses attention on a range of issues and questions. The fundamental premise of our analysis is that firm capabilities and perceptions differ within industries. This premise is not, however, widely reflected in analyses of industry behavior and performance, which typically take some representative firm as their starting point. Indeed, the analytic utility of our particular premise deserves scrutiny. Are differences in firm capabilities and perceptions as critical to explaining the industry patterns in innovative activity and performance as we suggest? Do these differences persist? Is our abstract characterization of these differences and their effects on innovative activity up to the task of providing a basis for policy?These intraindustry differences in capabilities and perceptions underpin the hypothesized relationship in our framework between the number of firms within an industry and the number of distinct technological activities pursued by the industry as a whole. Surely this hypothesis should be tested. To establish the relationship between numbers of firms and technological diversity, we also made two important assumptions, which themselves should be examined. First, we assumed that firms independently decide upon which approaches to innovation to pursue.This assumption precludes the clustering of firms around innovative activities due to imitation, a phenomenon highlighted by Nelson (1981) and Scott (1991). To the degree that innovative activities yield relatively fast, public results, the assumption may be suspect. While our evidence indirectly suggests that such clustering may not be critical for explaining innovative activity in a wide range of industries, more research would be helpful. Second, we assumed that the number of approaches to innovation pursued by firms is independent of their size, implying large and small firms will tend to pursue the same number of approaches. This assumption probably does not apply to the smallest firms within an industry, particularly to the extent that such firms are often not full line manufacturing firms. Does it apply, however, to the medium to large firms that account for the preponderance of R&D and economic activity inthe manufacturing sector? While our evidence again provides indirect support for this claim, more empirical and theoretical research is indicated.We also made other claims and assumptions that deserve further attention. For example, we argued that greater technological diversity stimulates technical advance and provides gross increments to social welfare. Assuming it exists, the mechanism linking diversity and technical advance has never been examined empirically and is not obvious. Our assumption that expected firm growth due to innovation is increamental played an important role in permitting usto hypothesize an appropriability advantage of large size. Again, both the assumption and its alleged effect on innovative activity are worth examining. Finally, we also need to test whether the relationship between R&D and firm size within industries depends upon appropriability conditions, particularly upon the extent to which firms can sell their innovations or grow rapidly due to innovation. In conclusion, this litany of reasonable but unsubstantiated assumptions and arguments should make clear that this paper is only a modest beginning of a daunting research agenda.

Learning Orientation and Performance Satisfaction as Predictors of Small Firm Innovation: The Moderating Role of Gender

Research on innovation in the context of small entrepreneurial firms is limited. Limited available studies on innovation in small firms are devoted mostly to firms operating in knowledge-intensive or technology industries and ignore the vast majority of small firms operating in traditional and less knowledge-intensive sectors of the economy. The rapid pace of technological change and the intensifying environmental turbulence in our economy influence all firms, including the majority of small firms that are perishing at a faster rate. Innovation is a key competitive tool for survival in a turbulent environment. Thus, it is important to understand factors influencing innovation in small firms. In this paper, we explore how learning orientation, a small-firm owner’s satisfaction with firm performance, and the firm owner’s gender influence innovation in small firms. We test the proposed model on a sample of small firms located in the United States of America.     

Product Innovation and Small Business Growth: A Comparison of the Strategies of German,U.K. and Irish Companies

Innovation in small firms is important both because of its direct contribution to the competitiveness of those companies but also because of the potential for the small firm sector to act as the initiator, catalyst and medium for wider technical change. In this paper data from the Product Development Survey, a new international survey of firms' product innovation activity and strategy, is used to examine the relationship between product innovation and growth in German, Irish and U.K. small firms. In each country the output of innovative small firms was found to grow significantly faster than that of non-innovators. In Germany, output growth was achieved by a product innovation strategy which sharply increased productivity but reduced employment. U.K. and Irish small firms adopted a more balanced approach with increases in both employment and productivity associated with innovative behaviour. Comparison of the organisation of product innovation indicated that German small firms adopted a less market-oriented, less risky, and more formally organised approach than their U.K. and Irish counterparts. The revealed characteristics of U.K. and Irish small firms suggested that they may be the most effective initiators and catalysts for wider technological change. The larger proportion of German small firms which were innovating, however, suggested that the German small firm sector may be the more effective technology transfer medium.     

Small and Medium Enterprises in Thailand: Recent Trends

This paper reviews the evolution of small and medium firms in Thailand in recent years. It shows that such firms did not preserve their share of total employment during the period 1987–96; indeed, their share fell from 60% to 52% over this period. Much of this decline was felt in the category of very small firms (with less than 10 workers). This aspect is explored further by looking at small firm employment shares in three sub-periods of varying overall economic growth rates. It is found that when overall economic growth is high, the share of small firms tends to contract possibly because many small firms become medium in size and others disband because their owners can find more remunerative employment in larger firms. In slower growth periods, the employment share of small firms appears to rise probably because larger firms may be taking in less new workers or even laying off workers. The paper also calculates productivity measures (technical efficiency and total factor productivity) and shows that different measures give different rankings by size of firm.     

The Exploration of Technological Diversity and Geographic Localization in Innovation: Start-Up Firms in the Semiconductor Industry

This paper examines the innovative ability of small firms in the semiconductor industry regarding their exploration of technological diversity and their integration within local knowledge networks. Through the analysis of patent data, we compare the innovative activity of start-up firms and larger firms. We find that small firms explore new technological areas by innovating in less crowded areas. The analysis of patent citation data reveals that small firms are tied into regional knowledge networks to a greater extent than large firms. These findings point to the role of entrepreneurial firms in the exploration of new technological spaces and in the diffusion of their accumulated knowledge through local small firm networks.     

Characterising Euro Area Multinationals

This study uses firm‐level data on a large sample of European manufacturing firms to investigate the links between opening up foreign affiliates and firms’ productivity. The analysis is guided by recent theoretical models of international trade with firm heterogeneity. The paper finds that while only a small share of euro area firms locate affiliates abroad, these firms account for over‐proportionally large shares of output, employment and profits in their home countries. They have higher survival rates and their productivity growth is also higher. The strongest contribution is by productivity growth of existing firms with a multinational status rather than entry into the multinational status. Finally, there are performance premia for multinationals with a large number of affiliates abroad relative to those with a small number.

Specialization versus diversity in Canadian technological development

In the new era of liberalized North American trade one of Canada's goals is export-led growth in technology intensive activities. Macro-economic data show that technology intensive specializations are developing but their international success is limited. One reason is that business spends less on R&D in Canada than in most OECD countries. Problems associated with macro data have prompted the use of survey-derived data listing the high-technology products of firms in order to define technological clusters. Most of the firms comprising each cluster are small: the distribution of large producers and R&D labs and the structure of clusters are discussed. Aggregate and micro data are used to establish the localization of technology intensive industry, especially in the Toronto metropolitan region. This is the largest concentration of technology intensive firms and the importance of services as markets and as sources of technology intensive products is established. The conclusion weighs the importance of specialization versus diversity, small firm entrepreneurship versus the importance of large firms, and metropolitan attraction for high-tech firms vs. the chances of medium-sized urban centres.     

Prior Knowledge and New Product and Service Introductions by Entrepreneurial Firms: The Mediating Role of Technological Innovation

Most research on new product and service development by entrepreneurial firms takes an individual‐level, prelaunch perspective or firm‐level postlaunch perspective. Our study examines two components of the new product and service introduction process: how entrepreneurs' prior knowledge underpins (1) firm technological innovation prior to the introduction of new products and services (prelaunch) and (2) postlaunch viability of those new products and services. Our findings, based on a series of analyses of data from 158 entrepreneurial firms, show that formal technological innovation fully mediates the relation between prior knowledge and the introduction of viable new products and services.     

Firm size,age, industrial networking,and growth: a case of the Korean manufacturing industry

This paper investigates the roles of firm size, age, and industrial networking in determining firm growth. Analyses using the 2-year panel data of 7,889 Korean manufacturing firms between 1994 and 2003 confirm that firm size and age have significant negative effects on firm growth and significant positive impacts on firm survival. R&D and export activities are found to facilitate both firm growth and survival. The primary focus of this study is to examine the effects of industrial networking, such as subcontracting and clustering, on firm growth. The results show that subcontracting does not yield any positive effect for firm growth, but encumbers survival, which may be accounted for by the high subcontracting intensity among small firms. Clustering, on the other hand, is found to promote firm growth and survival. There is, however, little evidence that such a positive effect of clustering is derived from network externalities through cooperation and competition among firms in a cluster per se.     

Small business survival and sample selection bias

Analyses of small business and the factors affecting their survival are fairly common in the research literature. The level of research interest may stem from the fact that in the US, only about half of all new small businesses survive after 4 years (Headd 2003). However, research attempting to understand the phenomenon that employs data using only information from and about surviving firms may lead to erroneous conclusions regarding the factors that influence firm survival and failure. In this paper, we provide evidence that omitted information about the firms that disappear from the research data over time leads to biased coefficient estimates. Comparing the Heckman two-step estimation approach of switching regression models to a semi-parametric Cox hazard model, the Accelerated Failure Time (AFT) model, we conclude that the Cox ATF approach is the most appropriate model for firm survival analysis.     

Innovation's Second Step

Innovative companies often place their emphasis on invention, research, and new product development, even as they neglect the process of bringing products to the marketplace in a way that is advantageous over the long term. Small to medium‐sized businesses that are scaling up are particularly vulnerable to entering into unfavorable distribution arrangements with large mass‐market retailers. Often, managers assume their firm will automatically benefit from a technological or creative breakthrough. Rather than focusing solely on new innovations and viewing distribution as an afterthought, we suggest that innovative firms make channel management a priority as their products are discovered and they attempt to reach more customers. In this article, strategies are offered as paths managers should consider as they use their innovations to scale up from small or medium‐sized firms into large companies. Steps for implementation as well as concurrent risks are also presented. © 2014 Wiley Periodicals, Inc.     

What do firms know? What do they produce? A new look at the relationship between patenting profiles and patterns of product diversification

In this work, we analyze the relationship between the patterns of firm diversification, if any, across product lines and across bodies of innovative knowledge, proxied by the patent classes where the firm is present. Putting it more emphatically, we investigate the relationship between “what a firm does” and “what a firm knows.” Using a newly developed dataset matching information on patents and products at the firm level, we provide evidence concerning firms’ technological and product scope, their relationships, the size-scaling and coherence properties of diversification itself. Our analysis shows that typically firms are much more diversified in terms of products than in terms of technologies, with their main products more related to the exploitation of their innovative knowledge. The scaling properties show that the number of products and technologies increases log-linearly with firm size. And the directions of diversification themselves display coherence between neighboring activities also at relatively high degrees of diversification. These findings are well in tune with a capability-based theory of the firm.     

Organizational innovation as an enabler of technological innovation capabilities and firm performance

This study assesses the relationship between organizational innovation and technological innovation capabilities, and analyzes their effect on firm performance using a resource-based view theoretical framework. The article presents empirical evidence from a survey of 144 Spanish industrial firms and modeling of a system of structural equations using partial least squares. The results confirm that organizational innovation favors the development of technological innovation capabilities and that both organizational innovation and technological capabilities for products and processes can lead to superior firm performance.     

Firm strategies in expanding and diversifying exports

This paper provides novel empirical evidence on the patterns and dynamics of exports by Irish firms over the past two decades from a highly detailed data set of export records at the firm‐product‐destination level. We identify patterns of export concentration and specialisation and how these evolved over time. Firms’ strategies for export growth along product and destination markets mixes are then examined and the contributions of intensive (average sales) and extensive (number of products or markets) margins to overall exports and to export growth are calculated. We find that most exporting firms are quite small, selling a few products to a small number of destinations while export values are dominated by a relatively small group of highly globalised large firms selling many products to many destinations. Continuing exporters frequently introduce new products, drop products and enter and exit markets. Export growth in the case of Irish‐owned exporters appears largely driven by the extensive margin of product and destination changes. However, the opposite pattern holds for foreign‐owned firms with growth mainly coming from the intensive margin.     

Does rising import competition harm local firm productivity in less advanced economies? Evidence from the Vietnam's manufacturing sector

This paper examines whether rising import penetration has an effect on the productivity of domestic firms. The study uses data on a 10-year unbalanced panel of firms in the manufacturing sector in Vietnam from 2000 to 2009. Panel and instrumental variable methods are used to control firm heterogeneity and endogeneity of import penetration. We find statistically significant and negative effects of import competition on local firms’ productivity, but the effect in terms of magnitude is economically small. Further investigation shows no clear evidence of variations in the effects by firm size and technological level. However, we find that rising import penetration is associated with the likelihood of firm death.

Firm growth during infancy

In this paper, we study the post-entry patterns of survival and growth of firms established in Portuguese manufacturing in 1983. Our data suggest the existence of a highly turbulent economy, with a very large number of small firms being created, but a great proportion of new firms disappearing in the first years subsequent to their birth. Survivors, however, grow quite fast and we found that small firms grow faster than their larger counterparts. Moreover, we found that the growth decision of firms is affected by a firm specific component, which is also correlated with firm size. These two effects are oppositely signed and, therefore, estimates that fail to take this firm specific effect into account are likely to be strongly biased towards zero.     

Why Small Firms Export: Another Look

This article examines what factors motivate small firms to export. Specifically, this study looks at firms with 200 or fewer employees, dividing the sample into two groups: firms with 25 or fewer employees and firms with more than 25 employees. The results suggest that firms with 25 or fewer employees export for two main reasons: the firm has a unique product, and it has a technological advantage over competitors. Firms with more than 25 employees export for the above two reasons, plus two additional reasons: to achieve economies of scale and to avoid losing out on foreign opportunities. Due to the limitations of the size and scope of this research, future research should include additional SIC categories as well as firms outside California.
