This paper takes agricultural production in China and its regions as the research object.Currently,China’s agriculture is in an important period of development,but there are many shortcomings in industrial structure and economic development.China has long taken plantation as the leading industry,but the per capita income is not high due to the low economic benefits brought by plantation.Therefore,adjusting the structure of agricultural industry is the key to promote the development of China’s agricultural economy,and is one of the important tasks of the government.In the structure of China’s economy,the adjustment and optimization of the agricultural industry structure assumes an important task.Agricultural production is a complex system influenced by many factors,including climate,geographical environment,land,labor force,market demand,technical conditions,policy bias and other factors.The impact of these factors on agricultural production will eventually be reflected in the gross value of agricultural industries,so the complexity of multi-factor analysis can be reduced by analyzing the gross value of four industries:agriculture,forestry,animal husbandry,and fishery.The purpose of this paper is to study the relative importance of each industry in the agricultural industrial structure based on the analysis objectives of multiple regions and multiple indicators,to establish importance evaluation indicators,to provide objective data,to improve the problem of too much subjective data in the hierarchical analysis method,and to select regions with a higher degree of optimization of the agricultural industrial structure by using the hierarchical analysis method(AHP).Through this method,scientific basis and decision support can be provided for the optimization of agricultural industrial structure.After years of development,China’s agricultural information construction has achieved remarkable results.Agricultural information resources on major websites have been flourishing.In this paper,we obtain data on China’s agricultural industry and screen and process the information therein.Through studying and analyzing the characteristics of the data and the information of agricultural industry structure contained in them,it is found that the index of total agricultural industry output value can better express the characteristics of optimization of agricultural industry structure in each region.Then,this paper analyzes the gross agricultural output value index,gross forestry output value index,gross livestock output value index,and gross fishery output value index in China,and translates them into the relative importance of each industry in the optimization of agricultural industry structure.Then,using the AHP model,the relative importance of each industry in the production of agricultural industry structure in China is calculated and analyzed.Meanwhile,this paper takes Chongqing as an example,analyzes its agricultural industry structure characteristics,and predicts the changes in the degree of optimization of agricultural industry structure after the support to different industries.It is finally concluded that China needs to reduce the scale of agricultural cultivation accordingly in the future,while expanding the scale of forestry and animal husbandry.At the same time,it is also necessary to strengthen the support for fisheries to improve its slow development,so as to optimize the agricultural industry structure.This will accelerate the pace of adjustment of China’s agricultural industry structure,accelerate the rate of farmers’ income and narrow the gap between the various regions of agriculture. |
