基于DEA方法的种业经济效益评价研究——以张掖市玉米种业为例

种业的高效发展对于保障我国农业可持续发展和粮食安全具有极其重要的作用。张掖是我国最大的玉米制种基地,其玉米种业发展对于中国玉米种业具有一定的代表性。以张掖玉米种业作为研究对象,通过构建评价指标体系,以DEA方法为手段,用Matlab软件进行数学计算,对张掖市2005-2014年玉米种业经济效益进行定量分析和评价。结果显示,张掖市玉米种业经济效益逐步达到最优,水平良好;种业规模效益处于递增或不变状态,具有很大发展潜力;制种资本投入和制种农户人均纯收入对种业经济效益影响较大。同时,为进一步发展张掖市玉米种业,提出相关建议,以期为中国玉米种业发展提供借鉴。

Studies on Economic Benefits Evaluation of Seed Industry based on DEA Model ——A Case Study of Zhangye Corn Seed Industry

High efficient development of seed industry is vital for ensuring the sustainable agriculture development and grain security in China. Zhangye is the largest corn seed production base in China. Its corn seed industry development has certain representativeness in Chinese corn industry. Taking Zhangye corn seed industry as research object, through constructing evaluation index system and adopting DEA as method, this paper did mathmetical caculation with Matlab software to analyze and appraise the economic benefit of Zhangye corn seed industry from 2005-2014. The results indicated that Zhangye corn seed industry had gradually achieved the best economic benefit; the scale benefit of corn seed industry was in the state of increasing or constant with great development potential. The capital investment of seed industry and net per capita income of seed producing farm households would exert greater influence on the economic benefits of corn seed industry. In order to further develop Zhangye corn seed industry, the paper put forward some suggestions, hoping to provide references for the development of corn seed industry in China.
