技术创新资源投入对高技术企业产品创新绩效影响的实证研究

Empirical Research on the Effects of Technological Innovation Resources Inputon the Product Innovation Performance of Chinese High-Tech Enterprises

以新产品产出作为测度我国高技术企业产品创新绩效的指标,以我国2003~2008年大中型高技术企业的面板数据为样本,应用广义矩方法对包括R＆D投入和非R＆D投入在内的技术创新资源投入对我国高技术企业产品创新绩效的影响进行了实证分析。结果显示：包括研发经费和科技人员在内的R＆D投入、非R＆D投入构成要素中的技术改造、技术引进、消化吸收对提升我国高技术企业产品创新绩效具有显著的直接正向影响。同时,研究发现技术引进、国内技术购买作为调节变量,显著提升了研发经费投入对高技术企业产品创新绩效的边际贡献;消化吸收作为调节变量,显著提升了技术引进和国内技术购买对高技术企业产品创新绩效的边际贡献。根据实证研究结论,为在开放式创新环境下提升我国高技术企业的产品创新绩效,本文进一步提出了针对性的对策建议。

With the panel data of Chinese large media sized high tech enterprises during the period from 2003 to 2008, this pa per empirically analyzed the effects of technological innovation resources input, including R＆D input and non R＆D input on the product innovation performance of Chinese high tech enterprises denoted by the new product output through using the method of general method of moments. The results show that R＆D input, including R＆D expenditure and scientists and technicians, and the several elements of non R＆D input, such as technology renovation, technology import, and adaptation ＆ assimilation have significant, direct and positive effects on the product innovation performance of Chinese high tech enterprises. Simultaneously, as the moderators, technology import and do mestic technology purchase significantly upgrade the marginal contribution of R＆D expenditure on the product innovation performance of Chi nese high tech enterprises, and as a moderator, adaptation ＆ assimilation significantly upgrades the marginal contribution of technology import and domestic technology purchase on the product innovation performance of Chinese high tech enterprises. According to the empir ical results, this paper put forward some valuable policy implications for Chinese high tech enterprises to boost their product innovation performance under the circumstance of open innovation.
