Meanwhile, due to the activities of takeover taken by the companies in the different trade life circles adopting different takeover types, so their performances are different. Seeing about this relationship, you can effectively inspect the efficiency of the market for corporate control. Adopting298 stylebook data from the market for corporate control in China, and through empirical analyzing, it can see that because of the existing of the stock holding, the efficiency of the market for corporate control in China is not very high. The government tempts to adjust the industrial structure through merger and acquisition （M＆A）, but it urged the aim of state-owned economy forward strategic transfer difficult to come true. To solve the contradiction of ＂setting up of the stock holding＂ comes to no time to delay. ＇展开更多

China has had its pilot carbon emission trading markets in seven regions for more than 3 years. What affects carbon emission trading market in China is a big question. More attention is paid to how China promotes the carbon emission trading schemes in the whole country. This paper addresses concerns about the functioning of carbon emission trading schemes in seven pilot regions and takes the weekly data from November 25, 2013, to March 19, 2017. We employ a vector autoregressive model to study how coal price, oil price and stock index have affected the carbon price in China. The results indicate that carbon price is mainly affected by its own historical price; coal price and stock index have negative effects on carbon price, while oil price has a negative effect on carbon price during the first 3 weeks and then has a positive effect on carbon price. More regulatory attention and economic measures are needed to improve market efficiency, and the mechanisms of carbon emission trading schemes should be improved.展开更多

In this article, the main influencing factors and mechanism of individual participation in carbon trading market are studied by establishing multiple linear regression model. The study found that age,education level, length of account opening time, and risk attitude are the main factors influencing the participation of individual investors. Environmental awareness and environmental impact are less affected; information transparency and transaction risk also have an impact on the degree of individual investor participation; investment experience does not affect the participation of individual investors in the carbon trading market.展开更多
