【摘要】:本文運(yùn)用DEA-Malmquist指數(shù)方法,測(cè)算了2008~2014年間31家中國(guó)石油企業(yè)全要素生產(chǎn)率,分析其時(shí)序演變及差異情況,并分別考察了全部石油企業(yè)、國(guó)有石油企業(yè)、民營(yíng)石油企業(yè)全要素生產(chǎn)率的收斂性。結(jié)果表明:12008~2014年,石油企業(yè)全要素生產(chǎn)率年平均下降3.3%,其中技術(shù)進(jìn)步平均下降5.1%,成為石油企業(yè)全要素生產(chǎn)率增長(zhǎng)的主要制約因素。2全部、國(guó)有及民營(yíng)石油企業(yè)全要素生產(chǎn)率趨勢(shì)變化基本一致,均呈現(xiàn)"M"型,民營(yíng)石油企業(yè)全要素生產(chǎn)率年均下降速度高于國(guó)有石油企業(yè)6%,高于平均水平3.3%,主要原因是民營(yíng)石油企業(yè)技術(shù)進(jìn)步下降幅度大,高于國(guó)有石油企業(yè)9.6%。3通過σ收斂檢驗(yàn)發(fā)現(xiàn),全部、國(guó)有及民營(yíng)石油企業(yè)間全要素生產(chǎn)率呈現(xiàn)發(fā)散——收斂——穩(wěn)定的態(tài)勢(shì),又通過條件β收斂檢驗(yàn)印證石油企業(yè)間全要素生產(chǎn)率正不斷趨近各自的穩(wěn)態(tài),意味著石油企業(yè)的穩(wěn)態(tài)增長(zhǎng)水平不同,企業(yè)間全要素生產(chǎn)率的差距會(huì)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.
