This work uses international economics and space economics theory to study the regional economic integration of China's border areas with the increasing integration of China's border areas, and to realize the theory and countermeasures of economic development across border areas. As China's economy pivots towards neighboring developing countries in Southeast Asia, new economic rhythms come into being; this book seeks to explore the practicalities thereof, in a text that will interest economic researchers, researchers of China's economy, and scholars of international relations.
