Problems And Optimization Of The Indicators System Of Green Bond Third Party Assessment Method

In recent years,economic growth and economic development have been accompanied by large-scale resource consumption,and the level of resource consumption brought about by economic growth and economic development has gone far beyond the normal range that the natural ecological environment can bear.The development of green industry should not only have strategic planning,but also be supported by financial industry.The emergence and development of green bonds play a very important role in promoting the protection of natural ecological environment and stable economic development,and the third party assessment and certification of green bonds,as an important link in the green bonds issuance process,has also been increasingly concerned by the relevant institutions and financial markets.Green bonds can increase the credibility of the issuers 'green bonds through third-party evaluation and certification,and get more investors' attention and trust.However,green bonds third party evaluation certification rapid growth,but also faced some problems.For example,the evaluation index weight determination is too subjective,certification index system selection differences are large.Therefore,the urgent task for green bonds is how to improve and optimize the problems existing in the third party certification and evaluation system of green bonds,based on China's National conditions,and guided by China's economic development,and driven by China's environmental protection.This is not only the driving force behind the development of green finance in the 13 th Five-Year Plan,but also crucial to the long-term development of green finance in China.This paper mainly analyzes the determination of the index weight of the third party evaluation and certification system in China,and takes the representative green bond assessment and certification method A method as an example,and uses the combination of the variation coefficient method and the entropy method to determine the index weight.Moreover,it can make up for the deficiency of the single assignment method and the weakness of the single assignment method when theentropy method or the variation coefficient method alone is used,so that the two kinds of objective enfranchisement laws can make up for each other's defects and realize the complementary advantage,which better reflects the effectiveness of the green bond third party's evaluation certification index system and makes the final index system more scientific and objective.It provides some reference information for the third party evaluation system of green bond and related policies.
