行业吸收能力差异如何影响中国OFDI的逆向技术溢出?

How Does Industrial Absorptive Capacity Influence China's OFDI Reverse Technology Spillovers?

采用DEA-Malmquist生产率指数法衡量各行业的TFP及其分解指数——技术进步变动(TC)和技术效率变动(EC),选取2004—2015年中国11个行业向14个代表性国家OFDI的面板数据,利用国际研发溢出模型检验贸易依存度、人力资本、研发投入和经济发展水平四个吸收能力指标对中国OFDI逆向技术溢出的影响,发现各个行业的吸收能力都在一定程度上促进了中国OFDI的逆向技术溢出。进一步地,以TFP作为被解释变量,利用Hansen门槛模型研究发现:超过门槛值之后,各个吸收能力对逆向技术溢出的影响更加显著,但一些行业目前依然没有超过门槛值。

DEA-Malmquist index is adopted to calculate the total factor productivity(TFP),which is further decomposed into technical efficiency change(EC)and technological progress change(TC).Selecting panel data of 11 Chinese industries OFDI in 14 representative countries from 2004 to 2015,this paper tests how the four absorptive capacity indicators,namely the trade dependence,human capital,R&D input and income level,affect the reverse technology spillovers by using the international R&D spillovers regression model.The results indicate that the absorptive capacity of all industries promotes the reverse technology spillover of China s OFDI to a certain extent.Furthermore,with TFP as the dependent variable,the Hansen threshold model is used to study the effect of absorptive capacity on Reverse Technology Spillover.It is found that the result is more significant when the absorptive capacity indicator exceeds the threshold level,and some of the industries are still below that threshold.
