Climate change has been a concern for governments and green groups around the world in recent years. This paper uses Dynamic Conditional Correlation with Mixed Data Sampling (DCC-MIDAS) model to analyze the four Standard & Poor's Indices representing green finance, green technology, clean energy and environmental responsibility, respectively. The four daily data series from July 31, 2014 to October 12, 2021 are respectively intercepted to study their long term and short term nexus. Results show that, in spite of the impact of the external macro events, the four variables have a strong positive correlation in most of the time in the selected sample range, and this nexus is stable and sustainable, which can resist certain external interference. Based on the conclusions, this paper tries to provide suggestions for policy makers so as to explore new ways to develop green finance, fund for green technology research and clean energy development, and reach the goal of reducing meteorological disasters and achieving green development.Climate change has been a concern for governments and green groups around the world in recent years.
