市场化改革既通过产权结构影响R&D投入,又通过影响市场化水平、新产品需求和筹资环境等市场环境对R&D投入产生影响。本文利用中国高技术产业1995—2010年的面板数据,运用动态面板的GMM方法实证考察了市场化改革对R&D投入的影响,得到以下主要结论:市场化水平的提高和新产品需求的增长对高技术产业R&D投入增长具有显著的正向影响,且人世后的正向影响更大;筹资环境的改善有利于促进高技术产业R&D投入的增长。国有产权过于集中不利于高技术产业R&D资本投入的增长,但却导致了过多的R&D人力投入。市场势力与R&D投入存在的非线性倒U型关系;企业规模对R&D资本投入的影响并不确定,但促进了R&D人力投入增长。
Market - oriented reforms affect R&D input through the ownership structure and the market environment which includes level of marketization and demand for new products and funding environment. This article selects the panel data of China' s high - tcch in- dustries during the period of 1995 to 2010, and using GMM method make an empirical analysis of the market- oriented reforms influ- ence on the R&D input. The result shows that improvement of level of marketization and growth of demand for new products have signif- icant positive impact on R&D input. Moreover the impact is more significantly after joining WTO. The improved funding environment promotes the growth of high - tech industry R&D input. Too concentrated state - owned property is against the growth of R&D capital investment, but it leads to too much R&D manpower input. Market power has a non - linear inverted U - shaped relationship with R&D capital investment and R&D manpower input. The influence of firm size on R&D capital investment is uncertain, but it has significant positive impact on the growth of R&D manpower input.
