本文从产品内分工的视角构建中国工业产业技术进步的计量模型,以2002-2012年中国27个工业行业面板数据为样本,实证研究我国参与全球生产网络对劳动生产率的影响。结果表明:产品内国际分工对技术进步促进作用因行业异质性而存在差异,各行业之间形成不同的技术进步方向和路径选择,中低端技术产业“进口中间产品—深加工—出口中间产品”对中低端技术产业的劳动生产率促进作用的较为突出,而高端技术产业的“进口中间产品—深加工—出口最终产品”方向对劳动生产率提高更明显。实证进一步揭示出我国应将仅对R&D投入数额本身的关注同时转移到对R&D内容的重视上,建立起从研发内容到研发投入的逻辑,制定适合自身发展特点的产业政策,提高R&D投入的使用效率,从而充分发挥产品内分工的促进作用,提高我国在全球生产网络中的嵌入层级,拉升国际分工地位,推动产业升级。
This essay constructs the econometric model of technological progress in China’s industrial industry from the perspective of intra-product division of labor. Taking the panel data of 27 industrial sectors in China from 2002 to 2012 as samples, this paper empirically studies the impact of China’s participation in global production networks on labor productivity. The results show that: the role of international division of labor within the product to promote technological progress varies due to the heterogeneity of the industry, and different directions and pathways of technological progress are formed among various industries. The middle and low-end technology industries include “intermediate products for import-deep processing-intermediate exports Product ”plays a more prominent role in boosting labor productivity in middle and low-end technology industries, while labor productivity is more pronounced in the high-end technology industries in the direction of“ imported intermediate products - deep processing - export of final products. ” The empirical study further reveals that our country should shift its focus on the R & D investment only to the R & D content at the same time, establish the logic of R & D investment, formulate industrial policies suitable for its own development and increase the use of R & D investment Efficiency, so as to give full play to the role of product division of labor to promote China’s global production network to enhance the embedded level, raise the status of the international division of labor, and promote industrial upgrading.
