本文基于世界投入产出表数据库和2005-2010年服务业行业面板数据,采用系统广义矩估计法对我国四种服务外包的全要素生产率效应及其影响机制进行了实证研究。研究结果表明:(1)离岸发包与在岸接包对服务业全要素生产率存在显著负向影响,在岸发包与离岸接包对服务业全要素生产率存在正向影响。(2)离岸发包与在岸接包对服务业全要素生产率的抑制作用来源于对服务业纯技术进步和技术效率的显著负向影响。(3)在岸发包与离岸接包对服务业全要素生产率的促进作用主要通过显著正向影响服务业纯技术进步实现。研究认为,中国未来应努力提高服务业整体规模和水平,加强服务业与制造业产业融合,推动服务业全要素生产率的提升。
Abstract
This empirical research studies the impact of four different service outsourcing in China on its total factor productivity (TFP) and further explores the impact mechanism, by using systematical generalized method of moments (GMM) based on both the WIOD and the panel data of service sector in China (2005-2010). The statistical results suggested that: (1) the TFP of service sector is negatively related with offshore outsourcing and domestic contracting while positively influenced by domestic outsourcing and offshore outsourcing; (2) offshore outsourcing and domestic contracting negatively influence the TFP through significantly impeding technique and efficiency enhancements; and (3) domestic outsourcing and offshore contracting enhance the TFP of service sector due to their positive effects on achieving technical improvements. Therefore, this research suggests that China should make more effort to improve the whole industry scale and developing ability of service sector, and reinforce the integration of service and manufacturing sectors, in order to enhance the TFP in service industry.
