摘要
当前我国光伏产业发展势头迅猛,但是不少企业依然存在成本高、收入少的财务问题。光伏发电市场的财务效率更将直接影响整个光伏产业的兴衰。对此以光伏发电上市公司为研究对象,建立了财务效率DEA-聚类分析模型,运用了DEA方法对其2015-2017年的财务投入和产出指标进行了效率分析和改进,并根据财务效率值对其进行聚类分析,最后做出综合性财务评价,以期对我国光伏发电上市公司的财务效率的提升给予借鉴作用。实证结果显示我国光伏发电上市公司的财务效率非有效,综合效率未达到有效,前沿的上市公司受规模效率的影响程度更大,公司的生产规模并未处于最优的位置。
At present, China′ s photovoltaic industry has a rapid development tendency, but manycompanies still have financial problems with high costs and low income. The benefits of the photovoltaicpower generation market will directly affect the rise and fall of the entire photovoltaic industry. For thispurpose, a photovoltaic power generation listed company was selected as the research object, and a financialefficiency DEA-clustering analysis model was established. The DEA method is used to analyze and improvethe financial input and output indicators for 2015 - 2017, the corporation are clustered according to thefinancial efficiency values. And finally a comprehensive financial evaluation was made in order to providereference for the improvement of the financial efficiency of China′ s photovoltaic power generation listedcompanies. The empirical results show that companies whose integrated efficiency has not reached aneffective frontier are mainly affected by the scale efficiency, their production scale is not in the optimalposition.
