技术引进与自主创新：替代或互补

The relationship between indigenous innovation and technology imports:substitution or complementarity

通过对替代互补关系的数理刻画,研究了我国工业企业技术引进与自主创新的替代互补关系。结果表明,总体而言,我国工业企业自主创新与技术引进之间具有较弱的互补关系;科技人才是影响自主创新与技术引进的重要因素。进一步从企业规模、所有制类型及技术水平三个层次来考察可以发现,在大中型工业企业、高技术工业企业以及国有控股工业企业中二者的互补关系较强,而在低技术工业企业中二者则显现出替代关系。研究结论对当前我国工业技术创新战略的正确定位具有一定启发意义。

This paper analyzes the relationship between indigenous innovation and technology imports based on the new analysis framework and the theory of Simultaneous Equation Model with Chinese industry level data. Generally speaking, the results show that the relationship in industries is complementarity, the scientist and technologist is the key factor that affects the indigenous innovation and technology imports. The complementarity relationship is very strength in large and medium-size industrial enterprises, high-tech industrial enterprises and state-owned industrial enterprises and enterprises whose controlling stake was owned by the state, but the relationship is substitution in low-tech industrial enterprises according to the enterprise size, system of ownership and technical competency. The results also give some hints to determine the appropriate strategy of technology development.
