  The creation of a new development paradigm that focuses on domestic cycle and features positive interplay between domestic and international engagements is a major strategic task concerning China's high-quality development, which falls on the shouders of national scientific and technological (S&T) power. Firstly, the paper presents a profound understanding of the importance of strengthening national S&T power to support the creation of new development pattern. Secondly, from the perspective of coordinated development and safety concern, the paper puts forward the overall approach and fundamental rules for the national S&T power to accelerate the creation. In the end, the paper elaborates on the major pathways in terms of safety, development and openness. Specifically, the institutional and systematic support should be strengthened and safety foundations for the new development paradigm should be solidified at first; secondly, the guiding role of innovations should be enhanced so that both the incentive and efficiency of the dual cycle system can be improved; thirdly, the level of opening up should be improved by aligning it with the nation's major regional development strategies.

  The central region connects the east to the west, the south to the north, and plays an important role in the coordinated development of regions across China. This paper first analyzes the characteristics of the central region in terms of national coordinated development from the national level, and then explains the situation that the coordinated development of the central region faces the "four no" problems, such as uncoordinated development between the north and the south, mismatching of economic agglomeration and population agglomeration, underdevelopment of special types of regions, and imperfect coordinated development mechanism. Finally, to tackle the "four no" problems, combined with the characteristics of coordinated development, this paper puts forward some policy suggestions from four aspects: constructing the spatial pattern of regional coordinated development, deepening the reform of the registered residence system in megacities, improving the development policy system for special types of regions, and improving the mechanism for coordinated regional development.

  Association standardization is a major innovation in China's standardization mechanism reform and the policy system is becoming increasingly mature. The development path of association standardization has undergone the exploring development - promoting part of development-comprehensive development phases, thus rapidly responding to market and scientific and technological innovation needs, and promoting application and diffusion of new technologies and new models. At the same time, the association standardization also has its deep-seated development problems. Based on the present situation of China’s association standardization, this paper introduces some lessons from the US, Japan and other foreign standardized mechanisms. Then suggestions are put forward to association standardization governance mechanism: (1) play the role of industry management departments and China Association for Science and Technology in improving social organization and association standardization governance; (2) strengthen the government's guiding role based on the whole life cycle of association standard formulation, implementation and internationalization; (3) cultivate standardization talents and jointly develop standards to comprehensively improve association standard quality.
