The Time-space Disparities And Autocorrelation Analysis Of Regional Economic Radiation In Northeast Sichuan Economic Zone

In 2016,Sichuan province issued the five economic zone's development plan for the first time.The plan including Chengdu Plain Economic Zone,South Sichuan Economic Zone,Northeast Sichuan Economic Zone,Panxi Economic Zone and Northwest Sichuan Economic Zone.The plan affirmed the economic development of the Northeast Economic Zone in recent years and put forward the aspects of infrastructure construction and industrial development of the Northeast Economic Zone.The development of Northeast Sichuan Economic Zone coincides with the construction of Chengdu Chongqing city agglomeration,The Belt and Road construction,the poverty alleviation planning of Qinba mountain and other aspects of opportunity,also meets with weak infrastructure,industrial transformation and upgrading,a single regional cooperation and other challenges.In the ten years of the concept of "Northeast Sichuan Economic Zone",this paper carries out the analysis of the economic development of the county economy in the Northeast of Sichuan province.The purpose is to provide the basis and suggestion for the optimization of county economic radiation in Northeast Sichuan economic zone.Based on the summary of previous studies,by selecting 12 representative economic radiation index,principal component analysis using SPSS,combined with the economic radiation model improved the calculated economic radiation intensity value of each county,analyze the differences between the ten years county northeast Sichuan Economic Zone economic radiation time.And using OpenGeoda and Arcgis related technologies,the paper makes a correlation analysis of the county economic radiation in the Northeast Sichuan Economic Zone with the Moran index and the LISA index as the representative.It can be concluded that the radiation of county economy in the Northeast Sichuan Economic Zone has a slow growth in time,and in the space,the distribution pattern of economic radiation field intensity has the conclusion of spatial agglomeration.At the end of this paper summarizes the method and theory,and presents a new prospect for the future research of the Northeast Sichuan Economic Zone.
