5、 energy companies in the short term.Because,when dealing with environmental policies,companies have to pay extra money on them,and the corporate earnings are reduced(Yanying Chen,2009).Samiah(2013)has the idea that environmental control policies will increase company cost.nHypothesis 1:Environmental

7、Beijing HypothesisHypothesisnIn China,traditional energy industries are mainly thermal power generation,coal and oil&gas,they also play important parts in listed energy companies.Coal companies can adjust the selling price according to the market.However,companies of thermal power generation and oil

8、&gas are limited.nHypothesis 2:In the short term,environmental Hypothesis 2:In the short term,environmental policies has a greater negative impact on the stock policies has a greater negative impact on the stock prices of the electric industry and the oil industry prices of the electric industry and
