本文基于DEA-Malmquist生产率指数法采用WIOD投入产出数据测算了2003-2011年中国细分行业部门的全要素生产率(TFP)及其分解变量,以及各行业部门的制造、服务离岸外包率及其前向、后向溢出效应变量。基于行业异质性的视角,考察了两种离岸外包对各行业TFP的直接与间接影响效应及其内在机制。研究表明:(1)制造离岸外包、服务离岸外包分别对非服务业部门TFP有显著负向、正向影响,对服务业部门TFP无显著影响。(2)制造离岸外包前向、后向溢出效应对非服务业部门TFP有显著负向影响,服务离岸外包前向溢出效应对非服务业部门TFP有显著正向影响;而服务业部门TFP不受离岸外包溢出效应的影响。(3)服务离岸外包通过正向影响非服务业部门纯技术进步和纯技术效率促进TFP提升;服务离岸外包对服务业部门纯技术效率有显著影响,而制造离岸外包对其分解变量无显著影响。
Based on the DEA-Malmquist productivity index method, we use WIOD input-output data to calculate the total factor productivity (TFP) and its decomposition variables of China’s subdivision sectors from 2003 to 2011, as well as the manufacturing and service outsourcing rates of various industries Its forward, backward overflow effect variable. Based on the perspective of industry heterogeneity, the direct and indirect effects of the two kinds of offshore outsourcing on TFP in various industries and their intrinsic mechanisms were investigated. The research shows that: (1) Offshore outsourcing and offshore service outsourcing have significant negative and positive impacts on TFP of non-service sectors respectively, while no significant impact on service sector TFP. (2) The forward and backward spillover effects of manufacturing offshore outsourcing have a significant negative impact on non-service sector TFP, and the forward spillover effect of offshore service outsourcing has a significant positive impact on TFP of non-service sectors; while the service sector TFP is not affected by the spillover effect of offshore outsourcing. (3) Offshore service outsourcing can promote TFP promotion by positively affecting pure technical progress and pure technical efficiency in the non-service sector; service offshore outsourcing has a significant impact on the purely technical efficiency of the service sector, while manufacturing offshore outsourcing has a significant impact on its decomposition variables No significant effect.
