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。
Based on WIOD and the Chinese industrial enterprises database,we investigate the effect of production fragmentation on the TFP of industrial enterprises in China from 1998 to 2011,testing the view that labor division can promote productivity. The main findings are as follows. Firstly,production segmentation significantly promotes the TFP. The overall and domestic production fragmentation have an inverted U effect,while the international production segmentation owns U-shape effect. Secondly,the characteristics of enterprises matter. The effect of the overall and the domestic production fragmentation on private enterprises and state-owned enterprises is obviously positive,while insignificant to foreign enterprises.Thirdly,the effect of production segmentation on the productivity of eastern enterprises is stronger than that of the central and western enterprises,and the effect is stronger for enterprises administrated by prefectural or below levels than for central or provincial enterprises.
