技术研发难度、市场竞争强度对新兴产业企业进入数量的影响研究

通过分析技术研发难度、市场竞争强度对新兴技术商业化过程中企业进入数量的影响，提出了企业进入数量差异性的三个假说，收集86个成功实现商业化的新兴技术数据，采用企业进入数量作为被解释变量，利用OLS和负二项回归检验了技术研发难度、市场竞争强度对企业进入数量的影响。研究发现，技术研发难度和市场竞争强度均正向影响了新兴技术商业化初期的企业进入数量，市场竞争强度负向调节了技术研发难度对企业进入数量的边际影响，并且这些促进效应不随时代变迁而产生显著差异。这解释了为什么新兴技术商业化成功时企业进入数量存在显著差异，揭示了企业进入数量乃至初始市场结构的内生性。

Research on the Impact of Technology R & D Difficulty and Market Competition Intensity on the Number of Enterprises in Emerging Industries

Based on the analysis of the impact of technology R&D difficulty and market competition intensity on the number of enterprises entering the new technology commercialization process, the paper puts forward three hypotheses of the difference in the number of enterprises entering into the commercialization process. The data of 86 successful commercialization emerging technologies are collected. The number of enterprises entering the market is used as the explanatory variable. OLS and negative binomial regression are used to test the impact of technology R&D difficulty and market competition intensity on the number of enterprises entering. It is found that both the difficulty of technology R&D and the intensity of market competition have a positive impact on the number of enterprises entering the initial stage of commercialization of emerging technologies. The intensity of market competition negatively moderates the marginal impact of technology R & D difficulty on the number of enterprises entering, and these promotion effects do not have significant differences with the changes of the times. This explains why there is a significant difference in the number of enterprises entering the market when the commercialization of emerging technologies is successful, and reveals the endogenous nature of the number of enterprises entering and even the initial market structure
