The core context of the book is to observe and understand China's complex and diverse business ecology "on the spot". The author abandons the conventional path of starting from theory or macro data, insists on going deep into the front lines of production, circulation, and transactions, starting from the underlying logic, and exploring how business forms in different regions are formed. The book takes a large number of specific cities as examples (such as Guangzhou, Xi'an, Suzhou, Chongqing, Wuhan, Changsha, Yiwu, Zhengzhou, Hefei, Panzhihua, etc.) And analyzes in detail how their unique natural geography, climatic conditions, industrial structure, demographic characteristics, transportation patterns, living habits, etc. Are transmitted layer by layer to shape different local business models and retail formats. The author not only presents phenomena, but is also committed to refining transferable "micro-decision-making" capabilities and business inspirations, and sums up specific business strategies such as "win-win integration, cost accounting to calculate urban economic accounts, and elimination of off-season".
