The Study on the 3E system coordination evaluation: Evidence from China

Since the introduction of economic reforms in 1978, China has become the world's fastest-growing major economy. But rapid economic development accelerates the process of urbanization, meanwhile resources and environment problems appear. Now, China has given energy and environment high priority in its economic stimulus package, drawing on goals set for the 12th Five Year Plan. The overall approach to environmental protection should continue to be improved during the next few years of recovery period. All of these goals are based on the development of energy, economy and environment (3E). Under this background, implementing the scientific concept of development, and promoting harmonious development among energy, economy and environment is the only choice for achieving sustainable development. The thesis studies the relationship among energy, economy and environment, and then combining the requirements of harmonious development of 3E system, proposes the concept of the coordinative development of 3E system. It is hoped to analyze the 3E coordination situation of 30 provinces of China to promote the sustainable development of 3E system. For this purpose, basing on the study of relevant indicator systems, following the criteria to select assessment indicator based on the system function and efficiency, the text builds 3E coordination degree indicator system framework including 33 specific indicators. In the next, it establishes a coordination evaluation model for 3E system based on the method of Canonical Correlation analysis and Coupling Coefficient Model in physics and estimates 3E coordination degree of 30 provinces in China, dividing them into three different categories: moderate disorder, mild disorder and barely coordination. Based on above results, the thesis finds a new way to promote the coordinative development of 3E system.
