我国新能源细分行业股票投资价值研究--基于熵权TOPSIS方法

Study on the Stock Investment Value of New Energy Industry Subdivisions in China Based on Entropy Weight TOPSIS

收集整理新能源行业个股并进行领域细分,选取衡量公司基本面的8方面26个指标,运用熵权TOPSIS方法综合评价各细分行业的股票投资价值,得出锂电与太阳能行业更具理论投资价值,节能照明与风能行业理论投资价值偏低,但在实际交易中锂电与核能行业的投资价值未被重视。最后从中长线投资角度表明太阳能与核能行业更具长期投资潜力。

This paper appraises the status of operation of listed companies in new energy industry subdivi- sions by analyzing the investment value of stocks. It can not only induct capital into efficient enterprises, but also provide references for the policy formulation on the strategic development of new energy industrry. It collects and subdivides stocks of this field, selects 26 indices in 8 aspects, and uses the methodology of en- tropy weight TOPSIS to evaluate the stock investment value of different subdivisions. It concludes that subdi- visions of lithium battery and solar energy are of more theoretical investment value. The comparison with ac- tual trading conditions shows that the investment value of subdivisions of lithium battery and nuclear energy has been neglected. The long-term analysis of policy orientation shows that subdivisions of solar energy and nuclear energy have a long-term investment potential.
