【摘要】：本文运用DEA-Malmquist指数方法,测算了2008~2014年间31家中国石油企业全要素生产率,分析其时序演变及差异情况,并分别考察了全部石油企业、国有石油企业、民营石油企业全要素生产率的收敛性。结果表明:12008~2014年,石油企业全要素生产率年平均下降3.3%,其中技术进步平均下降5.1%,成为石油企业全要素生产率增长的主要制约因素。2全部、国有及民营石油企业全要素生产率趋势变化基本一致,均呈现"M"型,民营石油企业全要素生产率年均下降速度高于国有石油企业6%,高于平均水平3.3%,主要原因是民营石油企业技术进步下降幅度大,高于国有石油企业9.6%。3通过σ收敛检验发现,全部、国有及民营石油企业间全要素生产率呈现发散——收敛——稳定的态势,又通过条件β收敛检验印证石油企业间全要素生产率正不断趋近各自的稳态,意味着石油企业的稳态增长水平不同,企业间全要素生产率的差距会持久存在。
[Abstract]:In this paper, the total factor productivity (TFP) of 31 Chinese petroleum enterprises from 2008 to 2014 was measured by using DEA-Malmquist index method, and the time series evolution and difference were analyzed, and all petroleum enterprises and state-owned oil enterprises were investigated respectively. The convergence of total factor productivity of private petroleum enterprises. The results show that the total factor productivity of petroleum enterprises decreases by 3.3a year from 1: 2008 to 2014, and the technological progress decreases by 5.1, which is the main factor of restricting the growth of total factor productivity of petroleum enterprises. The trend of total factor productivity (TFP) in state-owned and private oil enterprises is basically the same, both of which are of "M" type. The average annual rate of decline in total factor productivity of private oil enterprises is 6 higher than that of state-owned oil enterprises and 3.3% higher than the average level. The main reason is that the technical progress of private oil enterprises has declined greatly, which is higher than that of state-owned oil enterprises 9.6.3. Through 蟽 convergence test, it is found that all, The total factor productivity (TFP) between state-owned and private oil enterprises presents the trend of divergence, convergence and stability, and the conditional 尾 convergence test is used to prove that the TFP among oil enterprises is approaching their steady state. This means that the difference of total factor productivity between oil enterprises will persist.
