This paper summarizes the Economic Thought on Socialism with Chinese Characteristics for a New Era（ETSCCNE）from the Report of the 19th National Congress of the Communist Party of China. It holds that the thought belongs to the category of official economics. The direction of China’s economic construction is pointed out by the ETSCCNE. The academic research on the socialist economy with Chinese characteristics is the basic source of the ETSCCNE. However, we need a comprehensive economic theory to provide guidance for the socialist economic construction. That requires the innovation and perfection of the Socialist Economic Theory with Chinese Characteristics for a New Era（SETCCNE）. Therefore, it is necessary to manage the dialectical relationship between academic economics and official economics. Overall, the two are dialectically unified, that is to say the theoretical debates and theoretical innovation of the academic circles are the basic sources of the ETSCCNE. The academic research provides the realistic basis, theoretical sources and countermeasures and suggestions for the refinement of the official theory. Officials make choices, abstraction&refinement on the basis of academic researches and specify the research position and value orientation for academics. On the path of perfecting and developing the SETCCNE, we should adhere to the basic principle of benign interaction between official guidance and academic innovation, that is, the academic research should uphold the correct orientation of values and adhere to the people-centered philosophy, and then the academia should emancipate the mind, seek truth from facts and make innovation actively, so as to provide rich sources of ideas for the SETCCNE. In the direction of the innovation of the Socialist Economic Theory with Chinese characteristics, attention should be paid to whether it is compatible with the basic stratagem of the socialist economic construction with Chinese characteristics in the new era. The concrete criterions include, whether it holds the people-centered philosophy, whether it is beneficial for the realization of the goal that " on the basis of building a well-off society in an all-round way, we should build a prosperous and strong modern and powerful socialist democracy with harmony and beauty in two steps by the middle of this century”. The main task of developing and perfecting the SETCCNE is to give guidance to promote the productive forces and institutional innovation, and concentrate on resolving the new contradictions and problems in the construction of a modern economic system, thus fulfilling the requirements of " stronger confidence of path, theory, system and culture of socialism with Chinese characteristics”, and " neither taking the old rigid closed road, nor taking the evil way of changing the banner and flag”. All subordination can truly achieve a stronger China from a richer China and provide theoretical basis and strategies for building socialism with Chinese characteristics.
