传统产业、战略性新兴产业研发投入与补贴政策

R&D Investment and Subsidy Policies for Traditional and Strategic Emerging Industries

针对战略性新兴产业中研发投资市场失灵、政府补贴"退坡"问题,引入产业内补贴政策,将战略性新兴产业的发展分为4个阶段,研究不同阶段、不同补贴政策下传统企业和新进企业的最优研发投入策略。研究表明:在有政府补贴而无产业内补贴的情况下,政府补贴对传统企业和新进企业的研发投入具有"挤入效应";在既有政府补贴又有产业内补贴的情况下,新进企业的研发投入与政府补贴比例、产业内补贴比例和传统企业对战略性新兴产业的研发投入均正相关,同时行业内补贴的产生是有条件的;在无政府补贴而有产业内补贴的情况下,只有当补贴比例小于某一值时,产业内补贴才对传统企业和新进企业的战略性新兴产业研发投入具有"挤入效应";在无政府补贴也无产业内补贴的情况下,加大研发投入实现创新是企业的占优策略。

For strategic emerging industries, the intra-industry subsidies policy is introduced in view of the market failure in R&D investment and the decrease of government subsidies in, the development of strategic emerging industries is divided into four stages, then the optimal R&D investment strategy of traditional enterprises and newly-coming enterprises under different subsidy policies in different stages is studied. The results indicate that: the government subsidies have a "crowding-in effect" on R&D investment of traditional enterprises and newly-coming enterprises in the case with government subsidies and without intra-industry subsidies;in the case with gov-ernment and intra-industry subsidies, the R&D investment of newly-coming enterprises have a positive correlation with the proportion of government subsidies, the proportion of intra-industry subsidies and the R&D investment of traditional enterprises in the strategic emerging industries, in addition, the occurrence of intra-industry subsidies is conditional;in the case with intra-industry subsidies and without government subsidies, intra-industry subsidies can have a "crowding-in effect" on R&D investment of traditional enterprises and new enterprises in strategic emerging industries, only when the proportion of subsidies is lower than a certain value;and it is the dominant strategy for enterprises to increase R&D investment and realize innovation in the case without any subsidies.
