Simulation research on overall coordinated development in intra-county economic system

Based on Solow Economic Growth Model, considering various factors affecting the overall economic coordinated development of Jiangyin, dynamic evolution model can reflect the actual conditions of Jiangyin City. The simulation results indicate that Jiangyin still can obtain better development in economy in the next 40 years: output, knowledge, capital and input will increase greatly. The growth of population will get restricted due to resources and environment and meanwhile consumption of natural resources will rise. These indicate that if Jiangyin wants to keep the sustainable development of economy, it has to adjust the industrial structure, reduce the proportion of the second industry which depends more on resources, ecological and environment, speed up the development of modern service industry, and rely on the growth of knowledge for economic growth, which is the access to sustainable development of Jiangyin´s intra-county economic system.
