Research on the Measurement of High-Quality Economic Development in the Chengdu-Chongqing Economic Circle

With the profound understanding of the "Outline of the 14th Five-Year Plan (2021-2025) for National Economic and Social Development and Vision 2035 of the People’s Republic of China" and the "Outline of the Construction of Chengdu-Chongqing economic circle", the writers believe that in order to promote the high-quality economic development of the economic circle, it is paramount to correctly handle six major relationships. According to the connotation of high-quality economic development, a high-quality economic development system has been built, and the entropy method is used to empower the indicators. The writers introduce the principle of synergy into the study of the high-quality economic development of the economic circle. And the spatial evolution of high-quality economy (each dimension) of Chengdu-Chongqing economic circle is studied from two aspects: the synergistic development of high-quality economy from various dimensions, and the grade differences of high-quality economy from various dimensions, using modified urban gravity model and coefficient of grade differences. The results show that the degree of synergistic development of the high-quality economy from various dimensions of the Chengdu-Chongqing economic circle is relatively low, and there are large grade differences within the economic circle and inner city of Chongqing.
