摘　　要：山西煤炭工业在全国煤炭工业中占有重要地位,文中应用基于DEA的非参数Malmquist指数法,对2001～2008年中国27省区煤炭工业的全要素生产率进行了测算,并将其分解为技术进步指数和技术效率指数,重点研究了山西煤炭工业的全要素生产率的变动趋势及原因,结果表明:山西煤炭工业的全要素生产率平均增长了5.7%,主要原因在于技术效率水平的提高,而技术进步水平有所下降;进一步分解,在技术效率的提高中,基本上是规模效率在起作用,而纯技术效率没有得到改善。接着对山西煤炭工业的技术进步、纯技术效率、规模效率作了详尽的分析,最后给出提高全要素生产率的建议。Shanxi coal industry provides a significant component for China coal industry.Based on the non-parametric DEA Malmquist index method,the total factor productivity of coal industry in 27 provinces in China during 2001—2008 is calculated and is decomposed of technological progress index and technology efficiency index.we study mostly the tendency to the total factor productivity of Shanxi coal industry and the variation reasons.The main results show that the average increasing rate of total factor productivity of Shanxi coal industry is 5.7%,technology efficiency progress contributes most to the improvement of total factor productivity,the lever of technological progress decreases,furthermore scale efficiency progress is the prime cause of improvement of technology efficiency,the level of pure technology efficiency doesn＇t change.Then we analyze particularly technological progress,pure technology efficiency and scale efficiency of Shanxi coal industry.Finally according to these conclusions,the paper gives some recommendations on improving total factor productivity.
