利用随机前沿超越对数生产函数对我国区域要素规模效率的时变趋势、地域差异进行研究,并通过非效率函数对其宏观影响因素的效应进行了分析。总体看来,考虑影响因素后的效率估计值更为准确:1986—2005年的时变效率在外部环境因素变革的冲击下虽出现了波动情况,但总体上均呈现上升趋势;东部与中西部的效率变化趋势一致,但进入1990年代后东部的平均效率增长速度明显要快于中西部,且效率的东西部推移逐步扩大;另一方面,东西部区域内部的差异均呈现收敛趋势,且东部比中西部区域要显著的多。城市化、工业化、专业化、创新活动、人口素质等因素在不同地域不同发展时期对于效率均体现出不同的影响效应,因而,针对不同地区、发展阶段特征和区域特质其区域政策和发展模式的选择也要有所侧重。
By using the stochastic frontier logarithm production function, this paper studies the time-varying trend and regional difference of regional factor scale efficiency in our country and analyzes the effect of its macro factors by non-efficiency function. In general, the efficiency estimates after considering the influencing factors are more accurate: the time-varying efficiency in 1986-2005 fluctuated under the impact of changes in the external environment, but all showed an upward trend; in the eastern and central and western regions The average efficiency of the eastern part of China increased significantly faster than that of the central and western parts of the country after the 1990s and the efficiency of the east and west parts gradually expanded. On the other hand, the differences in the eastern and western regions showed a trend of convergence, and the east part More significant than the Midwest. Urbanization, industrialization, specialization, innovative activities, population quality and other factors have different effects on efficiency in different development stages of different regions. Therefore, according to the regional policies and development models for different regions, stages of development and regional characteristics The choice should also be focused.
