Research On The Development Of Underdeveloped County Industry Based On Multi-source Data

The county economy is an important part of the national economy,and the high quality development of the county economy is related to the healthy development of the whole national economy.Because the underdeveloped counties are restricted by resource conditions,comprehensive transportation,talent structure,information circulation and so on for a long time in the process of developing economy,the gap between them and developed counties continues to expand.However,the development of county industry is also the main force to promote the progress of county economy and society,the scientific nature of county industrial connection and layout is directly related to the quality of county economic development.The advent of the Internet information age has made multi-source data applications become possible.Therefore,the research of underdeveloped county industry based on multi-source data can enhance the scientific content of research,and also provide a general analysis and research framework for promoting the development of industry in underdeveloped areas.From the perspective of geography,this paper discussed the dynamic mechanism and optimization path of industrial development in underdeveloped county.And,based on the statistical data,questionnaire data,POI data and website information data of Chenxi county in Hunan province,the analysis methods such as GIS spatial analysis,mathematicalstatistics analysis and social network analysis are mainly used to study the industrial spatial layout and industrial correlation degree in Chenxi county industry development,clear Chenxi county industry development problems,and put forward optimization suggestions.The findings are as follows:(1)The dynamic mechanism of industrial development in underdeveloped counties is mainly composed of endogenous power,exogenous power,environmental power and associated power.By exploring the power layer and factor layer of the development of the underdeveloped county industry,the development path of the underdeveloped county industry based on the 5D analysis framework of increasing density,shortening distance,reducing division,reducing damage and making difference is finally constructed.(2)In terms of industry-in-industry linkages,The resource-based heavy industry has a strong pull on the industry of Chenxi county,while the high-tech industry has a low contribution to the economy.From the perspective of industry external investment,innovation organizations and potential market linkages networks,the investment flow in the province mainly comes from Changsha and Huaihua city,the type of investment industry still tends to be traditional and low-end,and the flow of investment outside the province mainly comes from Guangdong,Jiangxi and Zhejiang province.The core channel of the innovation organizationnetwork outside the industry is the connection between the local enterprises,and the innovation network of the government,industry,education and research is in the state of weak association.The potential market network development of characteristic industries in Chenxi county should focus on the expansion of the market in various cities and neighboring provinces in Hunan province,and improve the scale and specialized planting level of characteristic industries.(3)From the point of view of industrial spatial layout,the spatial pattern of leading agriculture and large-scale industrial enterprises in Chenxi county presents the characteristics of "western intensive east sparse,along the road distribution" and "overall dispersion,park agglomeration" respectively.The distribution of trade and service industry forms the spatial pattern characteristic of "one core,two axes and many poles ",and the spatial distribution of industry is obviously influenced by traffic directionality.The comprehensive development potential of each township is measured by entropy method,which is mainly divided into five types: high potential area,higher potential area,median potential area,lower potential area and low potential area.Different potential areas,township functions and industrial layout optimization measures are different.(4)Based on the problems existing in the analysis of industrial spatial layout and industrial relevance in Chenxi county,the paper putsforward the optimal path and countermeasures of response from the aspects of focusing on agricultural zoning,emphasizing industrial agglomeration,commercial and trade polarization-balanced development,promoting cultural characteristics,reducing regional division and reducing environmental damage.The next step is to focus on the quantitative analysis of the dynamic mechanism of industrial development in underdeveloped counties,pay attention to the interaction between underdeveloped counties and external elements from the perspective of flow space,explore the characteristics of industrial development in underdeveloped counties with different regional types,and construct a comprehensive,scientific and applicable theory system of industrial development in underdeveloped counties.
