开放经济条件下,一国或地区的自主创新能力受自身研发投入、外部技术溢出、市场需求等多重因素影响。笔者在理论分析国际技术扩散和内生需求因素对自主创新影响的基础上,运用1993年~2008年环渤海地区面板数据进行实证检验,结果表明当地自主创新能力的提升主要依靠自身研发投入和市场需求,而人力资源约束、收入差距及FDI挤出效应制约了自主创新能力的全面提升。
In open economy,the independent innovation capability of a country or area is influenced by many factors such as RD input,exterior technology spillover,market demand,etc.On the basis of the theoretical analysis of the impact of international technical diffusion and endogenous demand on independent innovation,the authors make an empirical study with the 1993-2008 panel data from the area around Bohai.The results show that the improvement of independent innovation ability around Bohai economic circle mainly depends on RD input and market demand,but the human capital,income gap and foreign direct investment restrict the allround improvement of independent innovation ability.
