摘要
本文运用DEA-BCC模型,对四川省21个地市州的人力、资本、能源和产出四个投入产出变量的生产松弛变量进行估算,考察四川各地区生产是否处于生产有效前沿面上。利用SBM方向性距离函数测算出各个决策单元的生产无效率值,进而构建并分解Luenberger全要素生产率(TFP)指标,对四川省2006年至2012年间经济增长效率变化趋势与因素进行分析。结果表明:(1)在研究期内,成都、自贡、攀枝花等五个地区始终处于生产有效前沿面上;(2)四川省经济发展整体上以成都为中心,愈向周边扩散,生产无效率逐渐严重,而资本和产出是无效率的主要来源;(3)全要素生产率的分解结果显示四川省整体生产绩效的提高主要来源于技术进步而非效率改善;(4)经济增长效率变化的要素分解表明,资本和产出是推动经济增长效率提高的主要因素。
The paper has used DEA - BCC models to estimate output slack variables of four input - output vari- ables consisting of human, capital and energy and productivity among 21 counties in Sichuan province and de- cide whether regional production in Sichuan has been placed on the efficient frontier. Then the paper has used SBM directional distance function to calculate the value of production inefficiencies of each decision unit, then build and decompose Luenberger total factor productivity （TFP） indicators to analyze economic growth efficiency trend and factors from 2006 to 2012 in Sichuan province. Results have shown the following four points. Firstly, within research period, five areas including Chengdu, Zigong, and Panzhihua have always taken the position of production effective frontier. Secondly, Chengdu is the economic center of Sichuan province, further around diffusion means less production efficiency, in which capital and output are the main source. Thirdly, decom- position results of full elements productivity have displayed that the improvement of overaU production perfor- mance in Sichuan province is main derived fi＇om technology progress rather than efficiency improvement. Fourthly, dements decomposition of economic growth and efficiency change have shown that capital and output are the main factors driving economic growth efficiency.
