摘　　要：在区分企业创新参与和创新水平的基础上,基于1998~2013年中国工业企业和授权专利的微观匹配数据,利用Heckman两阶段模型估计了企业规模和市场结构两类竞争因素对企业创新决策和创新产出的影响。研究发现:企业规模与市场结构对中国工业企业的创新决策和创新产出均有显著正向影响,且在外资企业、国有企业、出口企业和沿海企业中效果更明显,即大企业和一定程度的垄断可能更有利于创新的两个熊彼特假说在中国工业企业中均成立。研究结果显示,通过正常市场竞争产生的企业规模扩张和行业市场结构适度集中,不仅可以让更多中国企业参与创新竞赛以提高研发成功概率,还能通过提高企业创新产出冲破技术封锁和提高企业核心竞争力,实现企业创新参与和创新产出的双重提升。On the basis of distinguishing whether firms participate in innovation and innovation performance,based on the micro-matching data of Chinese industrial firms and authorized patents from 1998 to 2013,the Heckman two-stage model is used to estimate the impact of two competitive factors,firm size and market structure,on firm innovation decision and innovation output.Study found:firm size and market structure of China's industrial firms were significantly positive influence on decision making and innovation output,and the effect is more obvious in foreign-funded firms,state-owned firms,export firms and coastal,which means the two Schumpeter hypotheses that large firms and a certain degree of monopoly may be more conducive to innovation are both valid in Chinese industrial firms.The results indicated that the scale expansion of firms and the moderate concentration of industrial market structure generated by normal market competition can not only make more Chinese firms participate in innovation competition to improve the probability of R&D success,but also break through the technological blockade and improve the core competitiveness of firms by improving the innovation output of firms.
