Abstract:Faced with the global economic downturn and the continuous spread of COVID-19 epidemic, the uncertainty and instability of the international political and economic situation has increased. Based on theoretical logic and historical experience, it is not only the irreversible trend but also the inherent requirement of Chinas sustainable development of economy to build a new domestic and international dual cycle development pattern with domestic cycle as the main body, emphasizing linkage cycle, active cycle and dynamic cycle. In essence, the key to the formation of the new pattern lies in building a dual cycle endogenous power and fostering new advantages in international cooperation and competition. Specifically, it is to rely on the national strategy, take advantage of Chinas super large-scale market, multi-level consumer market and unified large market, to create a dual cycle endogenous market power. This need coordinated work which includes independent innovation as the core, and manufacturing service as the competitive new advantages, and the digital economy as a new opportunity to create a dual cycle industry support role. Moreover, it is important to improve the business environment, foster a dual cycle corporate dominant position, and form a high-level dynamic balance with higher quality supply and more dynamic domestic demand.

Abstract:By constructing the evaluation index system for the scientific and technological achievements transformation,this paper uses the minimum distance to the strong frontier method (mSBM) to measure the scientific and technological achievements transformation performance in China from 1998 to 2016. On the basis of analyzing the spatial correlation of scientific and technological achievements transformation performance,combined with the supply-side structural reform background,we use the spatial panel data model to empirically examine the influencing factors of the scientific and technological achievements transformation performance. The results show that Chinas scientific and technological achievements transformation performance shows obvious inter-provincial differences. Most of the eastern coastal provinces have relatively high scientific and technological achievements transformation performance,while the scientific and technological achievements transformation performance in the inland provinces of the central and western regions is not satisfactory. In terms of regions,the scientific and technological achievements transformation performance in the eastern region is the highest,followed by the central region and the lowest in the west region. After incorporating the spatial effect,scientific and technological achievements transformation performance not only shows spatial dependence in the global space,but also shows spatial heterogeneity in local space. The scientific and technological achievements transformation performance in most provinces is located in the spatial agglomeration area. A small number of provinces are in a spatially separated area. The results of spatial econometric model show that industrial structure,financial structure,human capital structure,economic development level,foreign direct investment effectively promote the scientific and technological achievements transformation performance,while property rights structure and government intervention have inhibited it.
