双向直接投资驱动产业动能转换机制研究--基于技术创新的中介效应

Analysis and Empirical Test of Two-way Direct Investment Driven Industrial Kinetic Energy : Based on Mediating Effect of Technological Innovation

采用倾向得分匹配联合渐进双重差分、两阶段最小二乘法以及多解释变量的单一中介效应检验方法,研究双向直接投资联动驱动产业新旧动能转换问题,得出以下结论:双向直接投资驱动产业新旧动能转换联动效应强度高于外商直接投资与对外直接投资个体效应;双向直接投资驱动产业新旧动能转换存在区域差异,东部沿海、北部沿海至西北地区驱动作用强度依次减弱;技术创新承担双向直接投资、外商直接投资、对外直接投资与产业新旧动能转换的中介。

The article uses the CEE statistical database,Zephyr and PWT9.0 databases,and adopts propensity score matching combined with progressive double difference,drawing the following conclusions:the strength of the linkage effect of two-way FDI driving the transformation of industries.The strength of the linkage effect for driving transfor-mation of new and old industrial kinetic energy is higher than the individual effects of foreign direct investment and outward direct investment.
