Mainstream economics is short of spatial dimensions for a long time because of its shortage of suitable technical tools, the emergence of D-S model and the foundation of new trade theory lay the technical basis for new economic geography which only focuses on macro heterogeneity but which lacks of microscopic heterogeneity, however, ‘new’ new trade theory provides microscopic theory basis for the producing of ‘new’ new economic geography. Based on the microscopic heterogeneity, ‘new’ economic geography promotes the perfection and development of the theoretical system of new economic geography whose theoretical model is mainly based on three analytic frameworks such as D-S monopoly competition analytic framework, OTT analytic framework and BEKJ analytic framework. Chinese scholars should actively use brand-new research vision and methods of ‘new’ new economic geography, and deeply study the intrinsic mechanism and optimal path of the spatial pattern of Chinese economic activities by combining China’s reality from simplicity to application and from imitation to innovation and breakthrough.
