Abstract: Based on the theory of symbiosis, this paper conducts a theoretical analysis of the economic and financial symbiosis and co-prosperity relationship, and measures the economic and financial symbiosis and co-prosperity. Panel data from China's provinces and regions from 1993 to 2017 is used to test the realization of economic and financial symbiosis and co-prosperity. The results show that China's economy and finance do have a symbiotic and co-prosperity relationship, but they are always in a positive asymmetric symbiosis state. The promotion of finance to the real economy is less than the contribution of the real economy to finance. Variables such as gradual economic reforms, financial reforms, financial macro-control policies, and government factors all affect economic and financial symbiosis and co-prosperity to varying degrees, and the impact of these variables on economic and financial symbiosis and co-prosperity has changed in different periods, which is an important force driving the evolution of the symbiosis system of economy and finance. In the new era, China should take Xi Jinping's thoughts on economic and financial symbiosis and co-prosperity as its fundamental guideline, further improve the level of economic and financial governance, straighten out the relationship between economy and finance, strengthen financial supply-side reforms, and promote the relationship of economic and financial symbiosis and co-prosperity to move forward to a symmetrical symbiosis model.
