In 2011, Ian Morris, a famous American historian, put forward that geography is the third force which determines the destiny of a nation's history in his book “How Long Will the West Dominate: Looking at the Future of the World from the Perspective of Historical Development Patterns”. The "geography" here is not based on the perspective of physical geography, but on economic geography. The 2009 world Development Report also points out that some places develop well because they all follow the three typical characteristics and connotations of regional economic integration and promote the change of geographical structure. The first is to increase density, the second is to shorten distance, and the third is to reduce fragmentation.The current reality of China's economy lies in the new normal pace characterized by "medium-high speed, superior structure, new power and multiple challenges", which makes it impossible to overcome the two obstacles of reducing overcapacity and break the "Hu Huanyong Line paradox". On the one hand, China has been embedding in the global value chain through processing and manufacturing links for a long time. As a result, in the special period of "three-phase superposition", China's economic growth lacks internal impetus and its industrial system is confronted with the dilemma of low-end development and overcapacity. On the other hand, excess production capacity has not been translated into actual welfare benefits for less-developed regions, and the unbalanced distribution of production capacity on both sides of the "Hu Huanyong Line" remains a difficult problem for China's economic geography.
