针对我国要素禀赋非均衡分布的客观现实,基于适宜性技术选择理论,本文利用1996—2014年省际面板数据构建区域异质性随机前沿生产函数,从供给侧视角探讨并解读三大区域资本积累动态效率差异及其成因。结果显示:尽管区域经济运行效率变化轨迹显著不同,但前沿技术选择与要素禀赋结构适配是资本积累动态效率的源泉。其中,东部因“适用技术”选择惰性致使前沿技术变迁滞后于要素禀赋结构演化而历经资本积累由动态无效到有效的过程;中部虽然选择了与其要素禀赋结构相对匹配的适宜技术且资本积累始终处于动态有效区间,却受制于高质要素供给上的“天花板效应”约束、各级人力资本技术吸收能力尚未达到溢出门槛,致使资本边际生产率持续下倾;西部前沿技术选择背离其非技能劳动比较优势而未能实现对总体要素的有效配置,资本积累动态效率提升缓慢并长期处于无效率运行状态。
According to the objective reality of unbalanced distribution of factor endowments in China and based on the theory of adaptive technology selection, this paper constructs the regional heterogeneity stochastic frontier production function using the provincial panel data from 1996 to 2014, discusses and interprets the capital accumulation in the three regions from the perspective of supply side Dynamic efficiency differences and their causes. The results show that although the trajectories of regional economic efficiency are significantly different, the combination of cutting-edge technology and factor endowment structure is the source of dynamic accumulation of capital. Among them, the eastern part chose the ineffective and effective process of capital accumulation due to laggard technological change of the leading edge due to the inert choice of “applicable technology” in the eastern part of the country. However, although the middle part chose the appropriate technology which is relatively compatible with its factor endowment structure and the capital accumulation Is always in the dynamic range, but is subject to the “ceiling effect ” constraint on the supply of high-quality elements. The absorptive capacity of human capital at all levels has not yet reached the threshold of spillover, causing the marginal productivity of capital to continue declining. The western frontier technology choice has deviated from its non- The comparative advantage of skills and labor but failed to realize the effective allocation of the overall elements, the dynamic efficiency of capital accumulation slowed down and remained inefficient for a long time.
