笔者在产出函数中以劳动生产率为因变量,引入人力资本、产业结构、城镇化水平为自变量对劳动生产率影响因素展开分析,选取全国286个地级市的数据面板为样本,使用FE、RE、Tw-FE、LSDV、FGLS等方法研究发现:从时间上看,人均资本存量对劳动生产率提升作用最大,但提升效果趋于稳定;人力资本投入、城镇化水平的提升效果处于增长的趋势中且人力资本投入的提升最具潜力;劳动力要素投入则显出规模不经济。从空间上看,人力资本投入、人均资本存量在中西部对劳动生产率的提升作用高于东部;城镇化水平的提升效果东部高于中西部;工业化程度在东部显出消极影响,中西部则呈现积极影响;而劳动力要素投入在东部和中部呈现规模不经济,西部则相反。综合来看,近阶段人力资本投入对于中国劳动生产率提升作用最为显著,我国要实现经济长期持续增长应注重人力资本的增值与纵深发展。This article introduces human capital investment, industrial structure, urbanization level, capital per worker and labor inputs in total output function to investigate how they influence labor productivity. Research methods as FE, RE, Tw-FE, LSDV, FGLS were used. Selecting the panel data of 286 prefecture-level cities, this article finds human capital investment, industrial structure, urbanization level and capital per worker have a significant effect on the promotion of labor productivity. In general, capital per worker has the biggest promoting effect on labor productivity, but the influence becomes stable. Human capital investment and urbanization level also improve labor productivity increasingly, besides, the human capital investment is the most potential core driving force. However, there is diseconomies of scale in labor inputs. From the perspective of space, the promotion force of human capital investment and capital per worker in the middle and west to enhance the labor productivity is higher than the east. In the east, the enhancing effect of urbanization is higher than the middle and west. Industrialization shows the negative impact on labor productivity in the east, but the situation is opposite in the middle and west. Furthermore, labor factor input is showing diseconomies in the east and middle, but in the west the situation is opposite. In general, the recent human capital investment has the most remarkable effect on the promotion of labor productivity in China, the increment and development of which should be highly valued to achieve long-term sustainable economic growth.
