高新技术产业是我国建设创新型国家的主力军,本文重点研究高新技术产业的生产效率问题。从Foster等(2008)的收入型全要素生产率函数出发,对Kasahara与Rodrigue(2008)生产函数进行扩展,搭建起较为完善的TFP理论框架,并基于国家统计局工业企业统计数据进行实证检验,发现:企业利润、人力资本、销售投入、中间产品对高新技术企业TFP发展具有显著的促进作用;我国研发投入带来的专利等技术产出很多,但实证结果中并未观察到研发投入对生产率的显著促进作用,银行贷款与政府补贴也存在类似情况,这说明我国政府过去所主导的研发投入模式与实际生产需要结合度不够高,相关科技体制与创新支持政策亟待调整。根据研究结论,并结合我国当前情况,给出具体的政策建议。
High-tech industries are the main force for building an innovation-oriented country in our country. This paper focuses on the production efficiency of high-tech industries. Based on Foster et al.’s (2008) income-based TFP, we extend the production function of Kasahara and Rodrigue (2008) to establish a relatively perfect TFP theoretical framework and conduct empirical tests based on the statistics of industrial enterprises of the National Bureau of Statistics. : Enterprise profits, human capital, sales inputs and intermediate products have a significant role in promoting the development of TFP in high-tech enterprises. There are many technologies such as patents brought by R & D in China. However, no empirical research shows that R & Which shows that there is a similar situation between bank loans and government subsidies. This shows that the combination of R & D investment mode led by our government and actual production needs is not high enough, and the relevant science and technology system and innovation supportive policies need to be adjusted urgently. According to the conclusion of the study, combined with the current situation in our country, give specific policy recommendations.
