Comprehensive Analysis Of The Development Of County Economy In Shandong Province

County economy is the cornerstone of our national economy,its economic activities involve the production,processing,circulation,consumption and other links of raw materials,as well as the primary industry,the second industry,the third industry of various departments.In 2002,the report of the 16th National Congress of the Communist Party of China formally put forward the "county economy" for the first time,after which"developing and strengthening the county economy" became the strategic goal of China's economic development.Shandong Province is the economic province of our country,but also the agricultural province,its economic development has the characteristics of "east work and west agriculture",its county economy can be regarded as the epitome of our county economy.So,this paper chooses Shandong Province as the research object.This paper mainly analyzes the development of county area in Shandong Province through factor analysis and systematic cluster analysis in multivariate statistical analysis.Considering the three aspects of reference,actual statistics and effect of factor analysis,this paper finally constructs a comprehensive evaluation system containing 24 indexes of 5 categories,and extracts 5 common factors by factor analysis,which are named economic scale factor,living standard factor,economic development speed factor,foreign trade change factor,industrial structure factor and get the corresponding factor score.In the application of factor analysis method,after getting each factor score,it usually takes the variance contribution rate as the weight to carry on the weighted calculation to get the comprehensive score,this score is often influenced by the first factor,the second factor and other principal factors,which to some extent masks the information of other factors.In order to get more comprehensive and detailed analysis,the five factor scores are systematically clustered in this paper,and the results are analyzed in combination with three-dimensional data map and administrative region partition map.The main conclusions are as follows:economic scale and residents'living standards,the province's county areas are quite different,Eastern Shandong Peninsula region has greater advantages,Northern Shandong region has relatively backward economy,and there are "strong city strong county "," strong city weak county "," weak city strong county "," weak city weak county ";In terms of economic development speed,the gap between the whole province is relatively small,and the development speed gradually decreases from Southwest Shandong to east Shandong Peninsula.There are "fast development cities" and "slow development cities";In terms of the degree of economic openness,some areas such as Boxing County and Guangrao County are heavily dependent on foreign trade,most of the region's economy is relatively closed,and a few areas such as Rushan City and Qu Fu City are seriously closed;n terms of industrial structure,the proportion of tertiary industry in the junction of Western Shandong Province is relatively low,and it tends to increase and then decrease towards the east peninsula.The development of county area is complicated,involving many fields and many specialties.There are still some shortcomings in the construction of indicators,research methods and so on.We hope that the follow-up can improve the research direction continuously,and expect that the research results of this paper can be helpful to the research of other specialties and fields.
