Vigorously developing green industries is an important support for achieving the goal of "double carbon". Since the beginning of this year, China's green investment has performed brilliantly. According to wind data, as of August 8, the total issuance of green bonds in China has reached 1.03 trillion yuan, an increase of about 53% compared with 669.5 billion yuan in the same period last year. A number of green projects have been launched this year, and the support of policies and capital has made green investment more active. Green investment shows a diversified trend. Wang Dongwei, chairman of Zhongtai Capital Investment Management Co., Ltd., told the reporter of Securities Daily that the green projects represented by new energy have large investment scale and long return period, and their sustainable development requires the opening of various financing channels. In order to encourage the market to increase investment and financing for green industries, the policy side continued to make efforts. In December last year, the Ministry of industry and information technology issued the "14th five year plan" for industrial green development, which clearly stated that it would increase fiscal, tax and financial support, promote the improvement of the green financial standard system and information disclosure mechanism to support industrial green development, support the listing financing and refinancing of green enterprises, and reduce financing costs. Since the beginning of this year, Sichuan, Guangdong and other places have successively issued documents to strengthen the support and service for green enterprises to go public, and guide various eligible green enterprises to go public for financing and refinancing. Wang Peng, a researcher of the Beijing Academy of Social Sciences and a researcher of the intelligent social governance research center of Renmin University of China, told the Securities Daily that equity investment in green projects is a hot field in recent years. On the one hand, green projects are subsidized by preferential policies; On the other hand, participating enterprises can realize their own transformation through green projects. The capital market will not only provide green industrial enterprises with preferential listing channels and convenient channels for refinancing, but also guide traditional enterprises to actively carry out green operations and help the formation of a green low-carbon circular development economic system in China. For example, in early 2022, Haiyin acquired Shenhui smart energy, transforming the company from power and thermal production and supply to distributed photovoltaic construction, smart energy city construction and other businesses, and further expanding the new energy business layout. In May, energy saving wind power announced that it planned to purchase 100% of the equity of tenghuang company by paying cash and undertaking debt. Tenghuang company is the main operator of the 50000 kW tenghuang wind power project in Julu County. Energy saving wind power said that it would expand its wind power business through acquisitions and mergers. Another big area is green bonds. Data show that by the end of June this year, the exchange market had issued nearly 500 green bonds, with a scale of 505 billion yuan. Zhang Cuixia, chief investment adviser of Jufeng investment, told the Securities Daily that with the support of the regulatory authorities, the amount of listed financing and refinancing of enterprises in the green energy, ecological protection and environmental governance industries is huge. The exchange has also established a "green channel", designed a unified logo for green bonds, and promoted the issuance of green corporate bonds. The types of relevant green stock indexes and green bond indexes continue to be rich. Wang Peng said: "green investment shows a diversified trend. According to different project needs, it can adapt to the financial support projects or explore new innovation models. The policy also supports innovation attempts in this area and constantly optimizes the market environment." Unified green standard, strong willingness to invest capital
