Does Climate Risk Affect Corporate Bond Yield? Take Shanghai as an Example

In this paper we collect data of corporate bonds and government bonds issued from 2005 to 2019 from CSMAR database. Firstly, we make a stepwise regression analysis and research on the impact of climate risk, selling back and cross-market transaction on corporate bond yield. The impact of climate risk on corporate bond yield is positive because if carbon dioxide emission is more, the earth will be warmer and sea levels will be higher, then companies will face more climate risks and corporate bond yields will increase. The impact from the selling back on corporate bond yield is negative because if the bond can be resold, the risk will be lower and the bond yield will decrease. The impact of cross-market transaction on corporate bond yields is positive because if corporate bonds cannot be traded, the liquidity of corporate bonds will be low, and the risk will increase, then corporate bond yield will increase. Secondly, logarithmic regression analysis of climate risk factors shows that the climate risk is still significant and the model fits well. Selling back, cross-market trading and other factors are significant, and the pattern is more significant. Compared with the original model, it can better explain corporate bond yield.
