摘　　要：本文采用生产率理论中的DEA-M指数方法分析了抽样调查企业1022户2000—2004年的数据,测度结果发现,样本期间企业的生产率增长处于下降态势,对生产率的分解则发现,这主要是由技术进步率的停滞不前造成的。通过对于生产率变量的面板数据的回归,本文发现,生产率增长很大程度上依靠外部市场需求来拉动,同时,资金来源依赖于国有银行的企业,其效率增长率显著高于其他企业。这个检验证实了在市场需求高速增长的条件下,企业生产率增长与外部融资支持的密切正相关,反之,没有融资支持的企业则得不到足够的发展和创新的空间,生产率增长会趋于减缓。Based on the panel data of enterprises survey in 2000-2004, we used the methods of DEA and Malmquist index to measure and decompose productivity of 1022 sample firms. We found the growth rate of productivity is decreased during the period, and it mainly caused by the stagnation of technical progress. We also found the firms productivity depend on push power of market demands very much, and it largely depend on the funds from State Banks. Our regression results confirmed the productivity of enterprises is very significant positive correlation to support by external raised funds. Otherwise, non - state enterprises, which have no enough supports by the banks or other securities in market, could not get enough room to promote productivity more rapidly than state finns. Therefore the growth rate of productivity would tend to be decreased.
