以我国24个省际2003~2010年的面板数据作为样本,建立省际大中型工业企业创新产出影响因素的分析框架。结果表明:只有R&D投入对创新产出的影响始终具有明显的正效应;而外商直接投资与技术引进经费都是负相关,但存在区域差异;国内购买技术经费支出对创新产出没有影响。上述结果说明,虽然通过引进技术和外商直接投资可以有效克服一些技术瓶颈,并且可以提供技术赶超和经济赶超的契机,但是R&D投入才是提高我国企业技术创新能力的最关键因素和最直接途径。
Taking the panel data of 24 provinces in China from 2003 to 2010 as samples, this paper establishes the analytical framework of the influencing factors of the innovation output of large and medium-sized industrial enterprises in the province. The results show that only the impact of R & D investment on innovation output always has a significant positive effect; while the direct investment of foreign direct investment is negatively related to the funding of technology introduction, but there are regional differences; and the expenditure on technology purchased domestically has no effect on innovation output. The above results show that although the introduction of technology and foreign direct investment can effectively overcome some of the technical bottlenecks, and can provide technical catch-up and economic catch-up opportunities, but R & D investment is to improve China’s technological innovation capacity of the most critical factor and the most direct way.
