Abstract： The driving force of China’s economic development in the new era is gradually shifting from traditional production factor inputs and export-led growth to scientific and technological innovation-driven development, and technological innovation is increasingly becoming the main engine of China’s economic development. China needs to urgently address difficult issues such as the disconnect between science and technology and the economy, as well as prominent problems such as repeated resource allocation and scattered scientific research forces. Under the complex and volatile development environment, it is necessary to further optimize the spatial collaborative allocation of innovation chains and industrial chains and promote the rational and scientific layout of regional economies. This study analyzes the spatial pattern and development trend of the widening regional differences in China’s innovation chains and industrial chains from the perspective of spatial layout. It is found that there is a mismatch between China’s technological support capabilities and the layout of innovative industries in the national territory. The internal links of the innovation chain are not closely connected, and some industrial chain resources have long allocation distances and short chains. The western region has difficulties in fully integrating into the eastern industrial chain. In response to these characteristics and issues, the study proposes an overall layout strategy of “grasping both ends and releasing the middle”, striving to guide the overall optimization of national economic spatial development by promoting the spatial collaborative allocation of innovation chains and industrial chains.

Abstract： As the fundamental goal of ecological civilization construction in the new era of China, the building of a Beautiful China is an important measure to promote the study of Chinese man-land relationships to a higher level and a new stage of development. This study takes the construction of ecological civilization of Beautiful China as the orientation, and carries on the frame design to the geographical landscape. The geographical landscape takes the elements of geoscience as the research object and makes a series of reasonable outlook about man-land system according to the interaction mechanism of human-land relationship and the influence of important uncertain factors, aiming to establish and maintain the sustainability of regional development. The geographical landscape of ecological civilization construction needs to be designed by elements, stages and regions. One of the important purposes of geographical landscape design of ecological civilization construction is to achieve the spatial balance of regional development. Therefore, its design is an extension of the spatial equilibrium model of regional development. The construction paths of different regional geographic landscapes are different. Each region should design unique construction plan of geographical landscape according to the specific characteristics of its own comprehensive development state. The reference value of United Nations’ SDGs for the geographical landscape design of ecological civilization construction in China is not as good as the relevant index system of advanced countries and regions such as the European Union and the United States, while it is of much significance to select the appropriate benchmark for the scientific and rational design of China’s geographical landscape.

Abstract： Heavy polluting industries are the important sources of industrial pollutant. Understanding the spatial agglomeration characteristics, influencing factors, agglomeration mechanism and environmental effects of China’s heavy polluting industries can help identify potential pollution risk areas to cope with increasingly severe environmental pollution problems. Based on the industrial economic data from 1999 to 2021, the spatial distribution and agglomeration characteristics of heavy polluting industries are characterized. It is found that: (1) Shandong, Jiangsu, Zhejiang, and Guangdong are the regions with high output value of the development of heavy polluting industries in the past 20 years, while Xinjiang, Inner Mongolia, Shanxi, Shaanxi, Henan, and Sichuan are the potential areas for the agglomeration of heavy polluting industries in the future. (2) Production cost (factor endowment), environmental regulation, economic development level, market share, and industrial structure are the key factors affecting the development of heavy polluting industries, and there is an obvious “inverted U” relationship between labor cost and heavy polluting industries development. (3) There is regional heterogeneity in the development of heavy pollution industries. The eastern region has a significant effect of pollution shelter, while the central and western regions have a more obvious orientation to seek low labor costs and resource enrichment. (4) The agglomeration of heavy polluting industries significantly increases the emission of industrial pollutants, and there is an obvious inverted U relationship with environmental pollution, but environmental regulations have not played a role in reducing pollution and emission. On this basis, the countermeasures and policy suggestions are further put forward to deal with the agglomeration of heavy polluting industries and reduce the potential pollution risk, providing reference to achieve the goal of Beautiful China.

Abstract： Major productive force distribution is a strategic deployment related to the medium and long-term regional development pattern of China in the next 15—20 years. Unfortunately, after reform and opening up, its importance as an organic component of China’s institutional advantages has been ignored for a long time. The study reexamines main theories of productive force distribution and rethinks their applicability in the market economy. Moreover, the historical changes of China’s productive force distribution have also been reviewed. China’s productive force distribution has experienced a development process from equilibrium, decentralization, and concentration to coordination. Finally, facing new situations and major issues, a strategic plan has been conducted. Major productive force should be guided by the guarantee of national strategic security and support an independent, complete and competitive modern industrial system. Major productive force should form an overall pattern dominated by “strategic development zone + special types of zone”, based on innovative regional economic complex, in national scale. Build an open major productivity layout system with multi-agent participation, continuously strengthen the eastern coastal strategic competitiveness, the western border strategic opening capacity, and the central and western strategic security capabilities, and support China’s regional economic layout and the second centennial goal of achieving complementary advantages and high-quality development.
