Abstract: The coordinated development of population, resources and environment is of great significance to promote the overall high-quality development of the region. This study taked Jiangsu province as an example, then used the entropy method to measure the level of coordinated development of population, resources and environment, and further analyzed the effect of coordinated development of population, resources and environment on economic development through impulse response. The results show that the level of coordinated development of population, resources and environment in Jiangsu province is good, but there is still a gap with the highly coordinated development stage; Compared with promoting the development of a single system, promoting the overall coordinated development of population, resources and environment has a longer-term impact on economic growth. Correspondingly, some suggestions are put forward to promote the coordinated development of population, resources and environment,such as the establishment of innovative research platform of population, resources and environment, the improvement of comprehensive utilization level and utilization efficiency of resources, and the development of new energy.

Key words: population, resources and environment, coordinated development, entropy method, impulse response
