本文采用WIOD和中国工业企业数据库数据,首次利用衡量生产分割程度的生产阶段数方法,考察了刻画全球价值链分工程度的生产分割对中国1998-2011年工业企业全要素生产率的影响,在经验研究层面研究了分工细化促进生产率提升的观点。研究发现:(1)生产分割显著促进了企业生产率,整体和国内生产分割对企业生产率有“倒U型”效应,而国际生产分割对企业生产率效应呈“U型”。(2)企业的特征影响生产分割对生产率的效应。整体和国内生产分割对民营和国有企业的效应显著为正,对外资企业影响不显著。国际生产分割对民营和外资企业效应显著为正,而对国有企业不显著。(3)生产分割对东部地区企业生产率的效应强于中西部地区,整体上对省级以下管辖企业的效应显著强于省级和中央管辖企业。
This paper uses WIOD and Chinese industrial database data to first measure the number of production stages that measure the degree of production segmentation, and examines the impact of the production segmentation that characterizes the global value chain sub-engineering on the total factor productivity of industrial enterprises in China from 1998 to 2011. At the level, we study the concept of division of labor to promote productivity improvement. The study found that: (1) The production segmentation significantly promoted the enterprise productivity, and the overall and domestic production segmentation had an “invert U-shaped” effect on the productivity of the enterprise, while the international production segmentation had a “U-shaped” effect on the productivity of the enterprise. (2) The characteristics of the company influence the effect of production segmentation on productivity. The effect of the overall and domestic production division on private and state-owned enterprises is significantly positive, and the impact on foreign-funded enterprises is not significant. The effect of international production division on private and foreign-funded enterprises is significantly positive, but not significant on state-owned enterprises. (3) The effect of production segmentation on the productivity of enterprises in the eastern region was stronger than that in the central and western regions. The effect of the production division on enterprises under the provincial level was significantly stronger than that of the provincial and central enterprises.
