生产性服务进口会抑制中国制造业自主创新吗

Will Import of Producer Service Restrain China's Innovation Capability

基于知识生产函数模型,运用2006—2011年23个制造业面板数据,测算生产性服务进口对制造业的技术溢出效应,并检验影响技术溢出吸收能力的主要因素。研究发现:生产性服务进口并没有抑制国内制造业自主创新;在创新要素投入效率方面,人力资本投入显著提高了创新产出和技术溢出吸收能力,而研发资本投入却不利于本国创新产出和技术溢出吸收能力;细分行业后发现,高技术行业通过生产性服务进口获得的直接技术溢出效应最强,其创新人力资本促进技术溢出吸收能力也明显强于中、低技术行业。

Based on know ledge production function,w ith the yearly panel data of 23 manufacturing sectors,this paper estimates the spillover effect from the import of producer service and the factors w hich decides the absorb capability are detected. The paper finds that import of producer service w ill promote the innovation capability through direct and indirect effects. Spillover effect w ill directly improve the innovation capability and in order to enhance the absorb ability,the increasing input of innovation human capital w ill indirectly promote the innovation capability. In addition,high- tech manufacturing sector w ill have more intensive spillover effect. Increasing innovation human capital input and improving innovation physical capital effectiveness w ill be important strategic choice serving the ＂innovation- driven＂strategy.
