| 内容提要 | 本文基于Francois（1990）模型并将之拓展至全球价值链分工情景，从理论上探讨生产性服务的增长机制与生产率效应，然后采用WIOD跨国投入-产出数据进行经验检验。研究发现，随着产出规模的扩张，价值链分工趋于深化、生产性服务就业比重趋于上升，而随着生产性服务就业比重的提高，最终产品/行业的全要素生产率趋于上升。但这因生产性服务活动所含劳动力要素的来源不同而存在差异：本国产出规模的扩张较大程度地提高生产性服务活动中源自本土的就业比重，而本国全要素生产率的上升则主要与生产性服务活动中源自国外的就业比重正相关。由此得到的政策启示是，在全球价值链分工背景下，推动本国市场开放与竞争，有助于扩大市场和产出规模、深化专业化分工，从而促进生产性服务增长以及经济效率提升。 |
| Abstract | This paper builds on Francois (1990) model to characterize the growth mechanism and productivity effect of producer services in the context of the global value chains. To test the idea, we conduct empirical regressions by using the WIOD transnational input-output datasets. The results show that, with the expansion of output, the GVC division of labor deepens and the labor input share for the activities of producer services increases, and with the rise of the labor input share for producer services, the total factor productivity (TFP) of final products/sectors tends to improve. But this differs with the source countries where the labor embodied in producer services comes from. That is, the expansion of domestic outputs will to a larger extent lead to the increase in the domestically originated producer services’ labor share, but the TFP of domestic final products/sectors is mainly positively correlated with the foreign-sourced producer services’ labor share. The policy implication is that, under the global value chains, making domestic markets more open and more competitive will help expand market and output scale, deepen specialization and division of labor, thus to promote the growth of producer services and economic efficiency. |
