We explore how a firm’s knowledge structure characteristics and market identity—as reflected in its position in the industry value chain and market status—influence knowledge-based alliance (KBA) formation. We propose that a firm’s propensity to form KBAs is affected by the congruence (or misalignment) between its knowledge structure characteristics (i.e., knowledge depth and scope) and the role it plays in the industry, as demanded by its position in the value chain. We further argue that while a firm’s market status can amplify the positive effect of the congruence, thereby enhancing a firm’s proclivity to form KBAs, being prominent can also hurt a firm when it faces a misalignment between its knowledge structure characteristics and externally induced expectations related to its value chain position. We validate our arguments using panel data on 1051 firm-year observations for 197 firms patenting in the global fuel cell industry for the period 1999–2009. By developing a richer understanding of the relationship between a firm’s knowledge-based resources and KBA formation, we answer the call for a better understanding of how and when firms can leverage their internal knowledge configurations to improve their proclivity to form alliances.  相似文献

The global process of strengthening and harmonization of intellectual property rights (IPRs) systems has been intensified in the last twenty five years by the signing of trade agreements (TAs) that include chapters with intellectual property (IP) provisions and other trade-related issues. This paper provides a first exploration of whether and how the signing of TAs with IP chapters influences bilateral trade flows for a balanced panel of 110 countries and the period 1995–2013. We address methodological issues related to the assessment of the effect of TAs on bilateral trade. We use matching econometrics to evaluate the treatment of TAs with and without IP chapters. In addition, we estimate the effects of TAs on bilateral trade in a more dynamic fashion using a panel data approach based on the gravity model. Also, we perform our analysis for trade in low- and high-IP intensive products. We found that both types of TAs increase bilateral trade but TAs with no IPRs chapters have a stronger positive effect on trade. However, if we include lags to consider that TAs with IP chapters might need a longer implementation time, the net expected increase on trade is similar for both types of TAs. We also found that the effects depend on the development level of countries and on the IP intensity of products. We found a clear positive effect for developed countries, but we do not observe important gains for developing countries in all sectors and to all destinations derived from TAs with IP chapters. This raises the question of whether trade gains can compensate the effort related with IP reforms.  相似文献

This paper explores the influence of innovation on the probability of survival of two hundred top British firms founded throughout the nineteenth and twentieth centuries. To this end, we have collected the firms’ significant innovations and classified them by Schumpeterian types, patented and non-patented and domestic and imported. The number of patents registered by the firms throughout their lifetime ?a rough measure of their incremental innovation activity– has also been recorded. In addition, twelve control variables ?five characteristics of the firms and seven of their business leaders– have been included. Both log-normal and gamma duration models have been used in the analysis. They have been estimated, firstly for the whole set of firms and, secondly, for the manufacturing and the service firms separately to control for industry differences. The results of the log-normal and gamma estimations are highly coincident, with some nuances. The significant innovations ?particularly new processes, non-patented and domestic ones– have been found to positively influence the probability of business survival. The number of patent applications seems to increase the survival probability of the manufacturing firms, but not of the service ones. Among the control variables, the firm’s size, its international dimension, and the age of the business leader at entry seem to be the most influential ones on business survival, although there are some differences between manufacturing and services. The main results are robust to the division of the sample by entry period.  相似文献

This paper analyses how knowledge-based practices adopted by innovation intermediaries enable them to generate value for themselves when collaborating with their clients. While the literature focuses on value creation for their client organisations, little is known about how innovation intermediaries create internal value even though this is essential for ensuring their long-term survival and sustaining their key facilitating role in the innovation system. This understudied issue is explored using empirical evidence from a sub-set of innovation intermediaries, Research and Technology Organisations (RTOs). The results indicate that by capitalising on existing knowledge vested in employees and collaborators as well as understanding and shaping the knowledge base of the innovation ecosystem, innovation intermediaries generate internal value from their involvement in collaborative innovation, which range from different financial to non-financial types of value. Implications for intermediaries, their collaborators and for policymakers are then discussed.  相似文献
