城市创新扩散效应比较研究——以上海、南京为例

Comparative Study of the Innovation Diffusion Effect in Cities --A Case of Shanghai and Nanjing

在采用Malmquist指数模型测算全要素生产率的基础上，利用改进的CH模型，对2003—2012年上海与南京两市的创新扩散效应进行对比研究。结果显示：上海作为我国典型的创新型城市，研究机构投入、研发人员、技术交易和外商直接投资都对其全要素生产率产生显著影响，而南京只有研发人员和技术交易额对全要素生产率产生显著影响，且外商直接投资均对两市全要素生产率产生反作用。最后，针对研究结果提出相关的政策建议。

Based on the Malmquist index model to calculate the TFP, and then use the improved CH model to study the innovation diffusion effect between 2002--2012 of Nanjing and Shanghai. The result shows： Shanghai as China＇s typical of innovative city, research institutions investment, R ＆ D personnel, technical turnover and foreign direct investment all have a significant impact on its TFP, but for Nanjing, only R ＆ D personnel and technical turnover have a significant impact on its TFE And foreign direct investment has a counterproductive to the TFP of both the two cities. Finally, the relevant policy recommendations are proposed.
