Spatiotemporal Evolution Characteristics and Influencing Factors of China’s Automobile Market since Joining the WTO

引用

Journal of Geographic Information System 2022年第5期14卷 410-429页

作者： Xibo Wu peiying Lyu Changqiang Lai Guangzhou Academy of Social Sciences Guangzhou China Guangzhou Urban Strategy Institute Guangzhou China

Since joining the WTO, China’s automobile market has shown a rapid development trend, and the automobile market is becoming more and more important to China’s economic recovery and high-quality development. The automobile manufacturing industry is one of the pillar industries of China, but facing downward pressure since 2018. The paper studies spatiotemporal evolution characteristics and influencing factors of automobile market since WTO Accession using methods including ESDA, DTW cluster analysis and Spatial panel Dubin model. The result shows that: 1) China’s automobile sales have grown rapidly and three development stages have occurred since WTO Accession;2) Four types of China’s automobile markets have significant spatial differentiation, while the same pattern present spatial agglomeration characteristics;3) The crucial reasons for spatial separation of production and sales in China’s automobile market include implementation of purchase restrictions in more and more cities, gradual consolidation of spatial pattern of automobile production, and the fact that some automobile production areas are far away from consumer market;4) The provincial spatial weighted average centers of automobile sales are mainly distributed in southeast Henan, and show a trend of moving to the southwest;5) The estimated coefficients of factors such as GDP, financial added value, the proportion of highway, the volume of highway freight, and implementation of automobile consumption incentive policies are all significantly positive, and some factors have positive spatial spillover effects. Existing research on the automobile market lacks analysis based on long-time series data. This study uses long-time series data to provide a certain reference for future research in related directions.

The Coastal Zone Loess of the Liaodong Peninsula, Liaoning Province

引用

Acta Geologica Sinica(English Edition) 1992年第3期66卷 311-324页

作者： Li peiying Cheng Zhenbo Lu Houyuan Liu Guohai First Institute of Oceanography, SOA, Qingdao, Shandong Liaoning Teachers University, Dalian, Liaoning Liu Linqun First Institute of Oceanography SOA Qingdao Shandong China

This Paper discusses the origin of the Coastal Zone Loess on the Liaodong Peninsula, Liaoning *** loess is composed mainly of proximal materials transported by low-altitude air flow and less commonly ofinland distal materials carried by high-altitude air flow. The main provenance is the Liaodong Bay. When thesea level declined during glacial period, the bottoms of the Liaodong Bay and Bohai Sea emerged, wheredesertization occurred. As a result, submarine sediments were transported by strong northwesterly winds to theeastern coastal zone of the peninsula and deposited there. These materials mixed with the windblown dust car-ried by atmospheric circulation from the interior of the continent, forming the loess.
