【摘要】:電力產(chǎn)業(yè)是國民經(jīng)濟和社會發(fā)展的重要基礎產(chǎn)業(yè),是保證我國社會主義現(xiàn)代化建設順利進行的基礎。在改革開放之前的計劃經(jīng)濟時期,我國電力行業(yè)屬于國家控制下的高度壟斷行業(yè),電廠數(shù)量較少,發(fā)電效率低下,電力能源匱乏,電力產(chǎn)業(yè)的發(fā)展速度跟不上經(jīng)濟發(fā)展的需求,社會對電力能源的需求無法得到滿足。改革開放三十多年來,我國對電力行業(yè)進行了一系列的改革,打破了一家辦電的壟斷格局,擴大了市場主體,讓更多企業(yè)參與到辦電中來,電力體制改革取得了明顯進展,加快了我國電力產(chǎn)業(yè)的發(fā)展速度。在這種情況下,研究電力行業(yè)(主要為發(fā)電企業(yè)),對發(fā)電企業(yè)進行績效分析,發(fā)電企業(yè)的經(jīng)營績效問題,對發(fā)電企業(yè)進一步提高效率有著重要的借鑒作用及意義。 本文首先回顧了國內(nèi)外企業(yè)績效評價理論的研究情況及對發(fā)電企業(yè)績效評價的現(xiàn)狀,敘述了我國電力產(chǎn)業(yè)發(fā)展與改革歷程,闡述我國電力行業(yè)存在的問題并利用SCP模型分析了我國電力行業(yè)現(xiàn)狀。本文采用數(shù)據(jù)包絡分析(DEA)方法對我國上市發(fā)電企業(yè)績效進行分析,結果顯示在樣本年份,我國上市發(fā)電企業(yè)整體效率有所提升,整體水平較好,但企業(yè)之間差異仍較為明顯。在此基礎上,再運用Tobit模型,對企業(yè)績效的影響因素作回歸分析,結果顯示我國上市發(fā)電企業(yè)績效與資產(chǎn)收益率呈現(xiàn)顯著正相關性。 根據(jù)本文實證分析的結論,結合我國電力行業(yè)的情況,給出相應的政策建議:繼續(xù)放寬對民間資本進入電力行業(yè)的限制;加強對電力企業(yè)經(jīng)營管理層的監(jiān)管力度,提高企業(yè)決策機構的運行效率;減少政府對電力行業(yè)的干預,鼓勵企業(yè)間兼并重組,,提高公司質(zhì)量,以此來促進企業(yè)績效的提升。
[Abstract]:Electric power industry is an important basic industry for the development of national economy and society. In the planned economy period before the reform and opening up, the electric power industry in our country belongs to the highly monopolized industry under the control of the state. The number of power plants is relatively small, the efficiency of power generation is low, the power energy is scarce, and the development speed of the electric power industry cannot keep up with the demand of economic development. Society's demand for electricity cannot be met. Over the past 30 years of reform and opening up, China has carried out a series of reforms in the electric power industry, breaking the monopoly pattern of a power company, expanding the main body of the market, and allowing more enterprises to participate in the operation of electricity. The reform of the electric power system has made remarkable progress. Speed up the development of China's electric power industry. In this case, the study of power industry (mainly power generation enterprises), the performance analysis of power generation enterprises, power generation enterprises operating performance issues, power generation enterprises to further improve efficiency has an important role and significance. This paper first reviews the research situation of performance evaluation theory of domestic and foreign enterprises and the current situation of performance evaluation of power generation enterprises, and describes the development and reform process of power industry in China. This paper expounds the problems existing in China's electric power industry and analyzes the present situation of China's electric power industry by using SCP model. In this paper, data Envelopment Analysis (DEA) is used to analyze the performance of listed power generation enterprises in China. The results show that in the sample year, the overall efficiency of listed power generation enterprises in China has been improved and the overall level is better, but the differences between enterprises are still obvious. On this basis, using Tobit model, regression analysis is made on the influencing factors of enterprise performance. The results show that there is a significant positive correlation between the performance of listed power generation enterprises and the return on assets in China. According to the conclusion of the empirical analysis in this paper, combined with the situation of the electric power industry in China, the corresponding policy suggestions are put forward: continue to relax the restrictions on private capital entering the electric power industry, strengthen the supervision and control of the management of the electric power enterprises, In order to improve the performance of enterprises, it is necessary to improve the operational efficiency of decision-making organizations, reduce government intervention in the power industry, encourage mergers and reorganization among enterprises, and improve the quality of companies.
