Agglomeration Degree And Influencing Factors Analysis Of Vegetable Specialized Villages In Beijing Suburb

The development of agricultural industry agglomeration is an important measure to realize agricultural modernization and an important starting point to promote rural revitalization.Vegetable village is an important carrier to realize specialized production of vegetable industry and plays an important role in promoting the development of vegetable industry agglomeration.In recent years,the vegetable industry,as a characteristic industry in Beijing,has continuously adjusted its industrial structure,gradually showing a good trend of continuous optimization of agricultural industrial layout,continuous promotion of agricultural specialized production and large-scale operation.The construction of vegetable specialized villages and towns has also achieved certain results and has initially formed a prototype of agglomeration.The study takes Beijing vegetable village as the research object,selects the relevant data of Beijing vegetable village and vegetable industry from 2012 to 2018,uses the location quotient index method to measure the agglomeration degree of Beijing vegetable village from two dimensions of time and space,and draws a conclusion that there is agglomeration phenomenon in Beijing vegetable village,but there is instability and fluctuation.Shunyi District,Tongzhou District and Pinggu District have a high overall agglomeration degree and maintain a stable agglomeration state.Using the method of concentration index calculation,the concentration degree is calculated from the total output value of professional villages and the number of employed farmers in leading industries.Generally speaking,the concentration areas are mainly concentrated in Shunyi District and Fangshan District.In order to better promote the agglomeration development of Beijing vegetable specialized villages,the study selects variables in combination with GEM model,and analyzes the influencing factors of agglomeration of Beijing vegetable specialized villages by constructing a common panel data regression model.According to the results,the agglomeration of vegetable specialized villages is mainly affected by the factors of large-scale operation,human capital,facility level,branding level and economic development level.The study suggests improving infrastructure construction,increasing scientific research investment,and creating a regional brand effect.Cultivate new business entities,promote industrial integration and development,give full play to the radiation and driving role of demonstration villages,and actively promote the construction of vegetable specialized villages,production bases and demonstration parks.
