Research on Development Evaluation of Low-Carbon Real Estate in Hangzhou City Based on DPSIR Model

At present, climate change characterized by global warming has become a crisis and challenge faced by the international community. Based on the reflection on the traditional real estate development model, energy-saving, environmental protection and green low-carbon real estate has attracted increasing attention. Based on the DPSIR model framework, this study constructs the evaluation index system of low-carbon real estate development, and uses the entropy right method to quantitatively evaluate the development level of low-carbon real estate in Hangzhou. The results show that in the process of low-carbon real estate development level in Hangzhou, the pressure and status showed a steady increase, respectively from 0.0515 and 0.0216 in 2017 to 0.1 852 and 0.2158 in 2021. The two subsystems of driving force and response decreased slightly in individual years, showing an overall increasing trend. The influence subsystem declined for two consecutive years in 2018 and 2019, and the downward trend in 2020 was contained and began to grow. The system comprehensive evaluation index increased from 0.2568 in 2017 to 0.9455 in 2021. The research shows that the development level of low-carbon real estate in Hangzhou has been rising continuously in recent five years and the development level is excellent in 2020 and 2021. From the rising trend of the system evaluation index, the low-carbon real estate will continue to develop in Hangzhou in the future and has a huge space for growth.
