外商直接投资对长三角高技术产业创新能力影响的实证研究

Empirical Analysis on the Effects of FDI on Self-Innovations Ability of Hi-tech Industry in Yangtze River Delta Area

选取我国长三角地区高技术产业20个行业2003—2012年的面板数据，构建计量模型，采用GMM方法分析FDI技术溢出与长三角及其两省一市高技术产业技术创新能力之间的关系。研究表明：外资企业的研发活动对长三角各地区高技术产业自主创新能力产生正的溢出效应，但没有研发经费投入力度的影响大；FDI对上海市内资企业自主创新能力的影响最大，其次是江苏省，浙江省最低；当地企业应该提高外商直接投资质量，合理控制投资力度。

This paper uses panel data of 20 hi-tech industries in Yangtze River Delta Area from 2003 to 2012. Based an econometric model, this paper employs GMM to estimate the relationship between technological spillovers from foreign invested enterprises and the innovative capacity of domestic high-tech industries in Yangtze River Delta Area. Then, according to the numerical analysis, the conclusions include that foreign invested enterprises＇ R＆D activities play a significant role in innovative capacity of local enterprises in Yangtze River Delta Area, that the absorptive capacity of domestic enterprises on the foreign advanced technique may be a pre-condition for Self-innovation, that the largest effect of FDI on self-innovations ability of hi-tech enterprises is in Shanghai City, followed by the Jiangsu province and Zhejiang province, then it is essential for the local enterprises to raise the quality of foreign direct investments reasonably controlled.
