Evaluation of Sustainable Development of an Agricultural Economy Based on the DPSIR Model

With today's rapid economic growth, the role of agriculture in production and life has come to the forefront. Many problems in China's agricultural economy have seriously constrained the vitality of Chinese agriculture. Therefore, it is necessary to further strengthen the study of an agricultural economy, inject new impetus into an agricultural development, develop targeted solutions, and lay a solid foundation for the sustainable development of China's agricultural economy. Therefore, in this paper, based on the theory of sustainable development of an agricultural economy, this paper constructs a sustainable agricultural development index system in Jiangsu province from five aspects of the DPSIR model: driving force, pressure, state, impact and response and uses principal component analysis to make a comprehensive evaluation of the level of sustainable agricultural development in Jiangsu province from 2010 to 2016. The analysis results show that Jiangsu's agricultural economy is overall better and steadily improving, and it has made a huge leap in the seven-year period from 2010 to 2016, showing better sustainability. We found that the state subsystem exposed some social problems after analyzing the subsystem, and if relevant measures are not taken in time to solve the emerged problems, it will affect the other subsystems and the sustainability of the agricultural economy.
