基于TOPSIS法的新疆农业生产比较研究

Comparative study on agricultural production of Xinjiang based on TOPSIS method

采用TOPSIS法与信息熵定权结合的方法研究新疆各地市农业综合投入、综合产出及农业综合效率的地区差异。研究结果表明,南疆、北疆区一(乌鲁木齐市、克拉玛依市、吐鲁番地区和哈密地区)与北疆区二(北疆其他地市)存在明显的区域差异,大体上农业综合投入由低到高分别是北疆区二、南疆、北疆区一,农业综合产出由低到高分别是北疆区一、南疆、北疆区二;农业生产综合效率则是北疆区一低,南疆中等偏低,北疆区二高。差异产生的主要原因,一是农业投入与自然资源的丰缺程度有关,自然资源相对丰富的区域,农业投入相对低;二是投入高低受经济发展程度制约,经济相对发达的地区,农业投入相对高;农业生产综合效率高低则依赖于农业投入与产出的相对大小。为提高农业生产效率,在实践中应尽量利用自然资源,合理投入,实现高效、资源节约型的农业生产目标。

This paper analyzed the differences of agricultural inputs,agricultural outputs and comprehensive agricultural efficiency between cities in Xinjiang based on TOPSIS method and entropy method.The results indicated that there existed obvious regional differences in South Xinjiang and North Xinjiang 1（Urumqi,Karamay and Turpan and Hami） and North Xinjiang 2（the other city in northern areas of Xinjiang）.The differences of the efficiency of agricultural productions were determined by the abundance of natural resources and the degree of economic development and the relative size of agricultural input and output.More abundant natural resources meant less agricultural inputs and more developed areas input more.To improve the efficiency,we should try to make use of natural resources and invest reasonably in the production.So we would achieve our efficient,resources-saving agricultural production targets.
