摘要
应用基于DEA的非参数Malmquist指数法,对1991—2004年中国18个地级以上煤炭类矿业城市的全要素生产率进行了测算,描述了全要素生产率的变动趋势并对其内在结构进行了分解;并以1998年为时序断点,分析了在煤炭城市发展的两个阶段中,全要素生产率变化的具体原因.结果表明:1991年以来,煤炭类矿业城市的全要素生产率年平均增长率为-0.8%,导致增长率降低的主要原因在于技术退化,而且这种退化呈现加速的趋势;1991—1997年间,效率改善导致大部分煤炭城市全要素生产率有所增长,而1998—2004年间,技术退步导致大部分煤炭城市的全要素生产率下降;开采历史较长的煤炭城市,14 a间无论是全要素生产率还是其分解成分,均大大落后于其它煤炭城市;1997—1998年间煤炭行业的"限产压库"政策,制约了煤炭城市的发展.
Based on the non-parametric DEA Malmquist index method, the total factor productivity of 18 prefectural level coal cities in China during 1991--2004 was calculated, and its variation and internal structure were analyzed. Taking the year 1998 as sequential breakpoint, we discussed the variation reasons for the total factor productivity of mine cities in two phases. The main results show that the average increasing rate of total factor productivity is --0.8% since 1991, technology regression is the prime cause of the falling tendency, and the regression is showing a tendency to deterioration during the 14 years. During 1991--1997, efficiency improvement leads the improvement of total factor productivity of most coal cities, and during 1998--2004, technology regression leads its decreasing. The traditional coal cities which have a long exploitative history have lagged behind other coal cities in not only total factor productivity but also its elements for 14 years. The policy that restricting coal enterprises＇ production and cutting down coal inventory has put a restraint on the development of all the coal cities during 1997--1998.
