改革开放以来,内地经济技术和创新水平的提高离不开源自香港的知识溢出。本文以广东省为例,运用1990~2010年粤港两地经济社会数据,从知识溢出角度构建知识生产函数模型,实证分析了香港知识溢出对广东省创新能力的影响。结果显示,知识存量和R&D资本存量是区域创新能力提高的主要因素,香港直接投资会对广东省创新能力产生轻微的负面影响,但粤港两地交流则对创新能力的提升具有正面作用。同时,广东省人力资本和信息通畅度会影响香港知识溢出效果,市场竞争度的提升则会扩大香港直接投资知识溢出产生的负面效应。在实证研究的基础上,本文针对如何提升内地整体创新水平提出了若干政策建议。
Since the reform and opening up, the improvement of economic, technological and innovation level in the Mainland can not be separated from the knowledge spillover originating in Hong Kong. Taking Guangdong Province as an example, this paper uses the economic and social data of Guangdong and Hong Kong from 1990 to 2010 to build a model of knowledge production function from the perspective of knowledge spillover, and empirically analyzes the impact of knowledge spillover in Hong Kong on innovation capability of Guangdong Province. The results show that knowledge stock and R & D capital stock are the main factors for improving regional innovation capability. Hong Kong’s direct investment will have a slight negative impact on Guangdong’s innovation capability, but the exchange between Guangdong and Hong Kong plays a positive role in enhancing innovation capability. At the same time, the degree of human capital and information flow in Guangdong Province will affect Hong Kong’s knowledge spillover effect. The enhancement of market competitiveness will increase the negative effect of knowledge spillover in Hong Kong’s direct investment. On the basis of empirical research, this paper puts forward some policy suggestions on how to improve the overall innovation level in the Mainland.
