【摘要】：為了更好的滿足社會日益增長的電力需求，一直以來電網(wǎng)建設(shè)受到了電網(wǎng)企業(yè)的高度重視，科學(xué)高效地開展電網(wǎng)建設(shè)項目投資也是學(xué)術(shù)界一直研究的課題。從資源合理配置的角度出發(fā)，為達(dá)到電網(wǎng)建設(shè)項目的經(jīng)濟合理性、避免因過度投資帶來能源浪費的發(fā)生，對電網(wǎng)建設(shè)項目進(jìn)行科學(xué)合理的投資效率評價是十分必要的，，而科學(xué)的評價方法的選擇尤為重要，這不僅能使各大電網(wǎng)企業(yè)的經(jīng)濟效率、社會效率等有效的相結(jié)合，還能夠為電網(wǎng)工程建設(shè)項目提供可靠的依據(jù)。 電網(wǎng)建設(shè)項目投資效率的高低將直接影響是否投資該項目的決策，要想科學(xué)合理地做出投資效率的評價，科學(xué)的評價方法至關(guān)重要。首先，闡述了投資效率評價的理論基礎(chǔ)，對投資效率的概念進(jìn)行了界定；其次分析了目前常用的效率評價方法的優(yōu)缺點，針對電網(wǎng)建設(shè)項目的特點，選取了DEA投資效率評價方法，并在信息權(quán)重“熵權(quán)法”上引入“區(qū)分度”的概念，來篩選電網(wǎng)建設(shè)項目輸入輸出指標(biāo)，并編寫了“熵權(quán)區(qū)分度”算法的軟件程序，形成了一套可以單獨運行的小型計算軟件。最后，根據(jù)電網(wǎng)建設(shè)項目的特點并利用DEA評價方法對山東某地區(qū)20座新建變電站項目進(jìn)行投資效率評價結(jié)果進(jìn)行分析比較，實證分析中引入“理想決策單元”的概念對各決策單元進(jìn)行了排序，從而驗證該評價方法的可行性和有效性。
[Abstract]:In order to better meet the growing power demand of society, power grid construction has been attached great importance to by power grid enterprises, and scientific and efficient investment in power grid construction projects has been a research topic in academic circles. From the point of view of rational allocation of resources, in order to achieve the economic rationality of power grid construction projects and avoid the occurrence of energy waste caused by excessive investment, it is very necessary to evaluate the investment efficiency of power grid construction projects scientifically and reasonably. The choice of scientific evaluation methods is particularly important, which can not only combine the economic efficiency and social efficiency of major power grid enterprises, but also provide reliable basis for power grid engineering construction projects. The investment efficiency of power grid construction project will directly affect the decision of whether to invest in the project. In order to evaluate the investment efficiency scientifically and reasonably, scientific evaluation method is very important. First of all, it expounds the theoretical basis of investment efficiency evaluation, and defines the concept of investment efficiency. Secondly, the advantages and disadvantages of the commonly used efficiency evaluation methods are analyzed. According to the characteristics of power grid construction projects, the DEA investment efficiency evaluation method is selected, and the concept of "differentiation" is introduced into the information weight entropy weight method. The input and output indexes of power grid construction project are screened, and the software program of entropy weight discrimination algorithm is compiled, and a set of small computing software which can run alone is formed. Finally, according to the characteristics of power grid construction projects and using DEA evaluation method, the investment efficiency evaluation results of 20 newly built substations in a certain area of Shandong Province are analyzed and compared. In the empirical analysis, the concept of "ideal decision making unit" is introduced to sort each decision making unit, so as to verify the feasibility and effectiveness of the evaluation method.
