Study On Analysis Method Of County Agricultural Technical Efficiency Based On GIS

Technical efficiency has long been a hot issue of regional economic research. Under thebackground of agricultural production facing natural resources constraints problem, how to make fulluse of limited resources, to improve the level of agricultural technical efficiency, and to ensure modernagricultural economy undergoing steady, fast and healthy growth, which has been a crucial issue inagriculture economic development. According to previous studies, we found that the Chineseagricultural technical efficiency has been in a downward trend in recent years, and the regionalagricultural technical efficiency differences were conspicuous, which has impeded the development ofagricultural economy. Therefore, based on the relevant theories and technologies about regionaleconomy, agricultural technical efficiency and geographic information system, proceeding from themicroscopic perspective of the county, taking agricultural technical efficiency as study object,combining the traditional agricultural technical efficiency evaluation methods and GIS-basedexploratory spatial data analysis techniques, this thesis conducted dynamic analyzing methods studies ofagricultural technical efficiency. On this basis, we took Hebei Province as an emipirical study,systematically evaluated the agricultural technical efficiency of140counties in Hebei Province from2001to2010, analyzed the dynamic agricultural technical efficiency evolution trend and differencesamong the counties, in addition, it also analyzed the main influencing factors which affected the countyagricultural technical efficiency, and put forward the countermeasures and suggestions to improve theagricultural technical efficiency. The main research work in this thesis are as follows:(1) The thesis firstly investigated the overseas research status of agricultural technical efficiency,analyzed the range, contents and methods of related studies. Aiming at the existed problems in domesticagricultural technical efficiency research situation, the thesis proposed that researchers shouldstrengthen the study on agricultural technical efficiency spatial analysis methods.(2) In view of the evolution economic geography, to build the theoretical framework of countyagricultural technical efficiency analysis, which laid the theoretical foundation for studying theagricultural technical efficiency. Taking county agricultural economy as a complicated system, the thesisintegrated agricultural location economy theory, county economy theory, spatial agglomeration theory,agricultural technical efficiency theory, evolution economic geography theory, and geographicinformation systems techniques and other knowledges of multi-disciplinary fields to syntheticallyanlayze the agricultural technical efficiency. The empirical results showed that the theoretical ideas canmore comprehensively and thoroughly analyze the essence of county agricultural technical efficiencyfrom dual dimensions of time and space.(3) The thesis proposed the method of combining stochastic frontier production function modelbased on the translog function with efficiency influcing factor analysis model to synchronously studythe county agricultural technical efficiency, the empirical analysis results showed that this model has apreferable fitting. (4) For the first time，the thesis put forward that the method combining the exploratory spatial dataanalysis method based on GIS technology with traditional agricultural technical efficiency model todynamiclly analyze county agricultural technical efficiency, which focus on analyzing the evolutiontrends and spatial distribution in the economic activity. The empirical results showed that thedynamic agricultural technical efficiency time and space analysis methods not only analyzes thetemporal evolutionary trends of county agricultural technical efficiency but also mines differences andspatial distribution features of agricultural technical efficiency among different counties. Andfurthermore, the study conducted from the county-level microcosmic perspective, which is in favour ofgrasp the within-province regional agricultural economic disparities, and tremendously enhancesauthenticity and practicality of samples.(5) According to the above theories and methods, the thesis conducted empirical analysis of theagricultural technical efficiency of140counties in Hebei province. The results found that there existedagricultural technical efficiency loss in counties from2001to2010, and the overall level of agriculturaltechnical efficiency is lower. The research described temporal and spatial evolution rule of countyagriculture technical efficiency in Hebei, and further analyzed the factors affecting the agriculturetechnical efficiency and spatial interaction mechanism among them, and finally some countermeasuresand suggestions to improve the county agriculture technical efficiency of Hebei are proposed. It is notedthat the methods has strong versatility, and can carry out other provinces and even national scaleresearch of agriculture technical efficiency, which will provide effiective decision-making support forresolving the problem of the unbalanced development of regional economy.
