【摘要】：電力行業(yè)是國民經(jīng)濟的支柱性行業(yè),隨著國民經(jīng)濟的高速發(fā)展,用電負荷的規(guī)模也在一步步的擴大。為了保障電能供應,電網(wǎng)公司需要不斷加大電網(wǎng)建設(shè)。電網(wǎng)公司投資建設(shè)的項目在微觀層面會對周邊居民和企業(yè)的生產(chǎn)生活產(chǎn)生影響,在宏觀層面則對整個地區(qū)的經(jīng)濟發(fā)展有著深遠的影響。電網(wǎng)大規(guī)模建設(shè)在有效改善電網(wǎng)運行條件的同時,也因為建設(shè)融資來帶的財務壓力以及電網(wǎng)設(shè)備利用率低的原因?qū)е碌耐顿Y效益低等問題,給電網(wǎng)公司管理經(jīng)營帶來巨大壓力。在新的環(huán)境下,需要進一步完善電網(wǎng)投資評價體系,對電網(wǎng)建設(shè)投資進行多角度評價,多方面衡量電網(wǎng)投資建設(shè),從而為電網(wǎng)公司的投資管理工作提供更好的參考�；诖�,本文在研究電網(wǎng)投資效益理論以及電網(wǎng)企業(yè)現(xiàn)行投資評價存在的問題的基礎(chǔ)上,并結(jié)合前人的部分研究成果,首先提出了四層級較為全方位的的電網(wǎng)建設(shè)投資與評價標準體系。并引入灰色聚類三角函數(shù)進行電網(wǎng)建設(shè)綜合評價,以更好的對處于不同發(fā)展階段的各指標值進行歸類與綜合評分。首先,本文介紹了投資效益的內(nèi)涵,并分析了電網(wǎng)企業(yè)投資評價及投資管理現(xiàn)狀及其存在的問題。其次,從SMART原則出發(fā),在綜合考慮投資、收益、資產(chǎn)等三種因素的基礎(chǔ)上,構(gòu)建了包含主網(wǎng)投資評價、配網(wǎng)分公司投資評價、分專業(yè)投資評價和分電壓等級投資評價等多級電網(wǎng)投資評價標準體系,共計56個關(guān)鍵指標。第三,采用相關(guān)性分析法對關(guān)鍵指標進行約簡,再根據(jù)指標自身特性對其進行歸一化處理。在綜合考慮了不同類型的主客觀賦權(quán)方法后,本文選取德爾菲法、變異系數(shù)法以及熵權(quán)法等三種方法進行線性組合賦權(quán),以盡量保證評分的合理性。最后,本文選取某省級電網(wǎng)公司近兩年的數(shù)據(jù)進行模型的實證分析,最終分別給出不同地市的主網(wǎng)架、配網(wǎng)、分專業(yè)電網(wǎng)及分電壓等級電網(wǎng)投資評價綜合評分。在此基礎(chǔ)上,通過各地區(qū)分公司的實際情況驗證模型的合理性,并針對最終評分給出具體的公司投資策略,以期為該公司的電網(wǎng)建設(shè)提供支持與借鑒。論文的研究成果省級電網(wǎng)公司的電網(wǎng)建設(shè)投資評價與投資管理提供較為全面的參考,有利于推動電網(wǎng)的快速、優(yōu)質(zhì)發(fā)展,有利于加快電網(wǎng)投資、提升資產(chǎn)質(zhì)量,打破電網(wǎng)瓶頸對社會經(jīng)濟發(fā)展的阻礙,為社會經(jīng)濟發(fā)展提供堅實的電力保障。
[Abstract]:Power industry is the pillar industry of national economy. With the rapid development of national economy, the scale of power load is expanding step by step. In order to ensure the power supply, grid companies need to increase the power grid construction. The investment and construction projects of power grid companies will have an impact on the production and life of the surrounding residents and enterprises at the micro level, and on the macro level on the economic development of the whole region. The large-scale construction of power grid not only effectively improves the operating conditions of the power grid, but also brings great pressure to the management and management of the power grid company because of the financial pressure brought about by the construction financing and the low investment efficiency caused by the low utilization of the power network equipment. In the new environment, it is necessary to further improve the evaluation system of grid investment, to evaluate the investment in power grid construction from various angles, and to measure the investment and construction of power grid in many ways, thus providing a better reference for the investment management work of power grid companies. Based on this, this paper studies the theory of grid investment benefit and the problems existing in the current investment evaluation of power grid enterprises, combined with some previous research results. Firstly, a four-level and all-round investment and evaluation standard system for power grid construction is put forward. The grey clustering trigonometric function is introduced to the comprehensive evaluation of power network construction to better classify and evaluate the index values in different stages of development. Firstly, this paper introduces the connotation of investment benefit, and analyzes the present situation and existing problems of investment evaluation and investment management of power grid enterprises. Secondly, on the basis of smart principle and considering three factors: investment, income and assets, the paper constructs the investment evaluation of the main network and the investment evaluation of the branch company of distribution network. There are 56 key indexes in multi-level grid investment evaluation standard system, such as professional investment evaluation and sub-voltage grade investment evaluation. Thirdly, the key indexes are reduced by correlation analysis and normalized according to their own characteristics. After considering different types of subjective and objective weighting methods, this paper selects Delphi method, coefficient of variation method and entropy weight method to carry out linear combination weighting, in order to ensure the rationality of the score as much as possible. Finally, this paper selects the data of a provincial power grid company in the past two years for empirical analysis, and finally gives the comprehensive evaluation scores of the main grid, distribution network, specialized grid and voltage grade grid investment evaluation of different cities. On this basis, the rationality of the model is verified by the actual situation of each regional branch, and the specific investment strategy of the company is given according to the final score, in order to provide support and reference for the power grid construction of the company. The research results of this paper provide a more comprehensive reference for the investment evaluation and investment management of power grid construction in provincial power grid companies, which is conducive to promoting the rapid and high-quality development of the power grid, speeding up the investment in the power grid, and improving the quality of assets. Breaking the bottleneck of power grid hinders the development of social economy and provides a solid power guarantee for social and economic development.
