普遍认为企业进行研发主要有三种目的,即开发新产品、提高生产技术以及提升产品质量,那么中国企业研发投入的主要目的为何?利用2005-2007年中国制造业企业数据,分别按照新产品比率、生产率以及价格—成本加成率衡量企业产品创新、生产技术以及产品质量,进行实证检验发现:(1)企业研发对于产品创新与技术增进可能具有显著的促进作用,而对于质量提升的促进作用难以确定;(2)在控制相同变量的标准化回归中发现研发对于产品创新的贡献最大,其次是技术增进,最后是质量提升。据此认为中国企业进行研发主要目的可能是产品创新,其次可能是增进技术,而研发对于提升产品质量的作用相对较小。
Generally speaking, the main purpose of R & D for Chinese enterprises is to develop new products, improve production technology and improve product quality. There are three main purposes for enterprises to carry out research and development: using the data of Chinese manufacturing enterprises from 2005 to 2007, Productivity and price-cost-plus rate measure enterprise product innovation, production technology and product quality, empirical test found that: (1) enterprise research and development for product innovation and technology promotion may have a significant role in promoting, and for the promotion of quality is difficult to promote (2) In the standardized regression of controlling the same variables, it is found that R & D contributes the most to product innovation, followed by technology improvement and finally quality improvement. Therefore, the main purpose of R & D for Chinese enterprises may be product innovation, followed by promotion of technology, while R & D plays a relatively small role in improving product quality.
