Post-evaluation of well-facilitied capital farmland construction based on entropy weight method and improved TOPSIS model

Abstract: In the context of a large-scale well-facilitied capital farmland construction, scientifically evaluating its effect and influence of post-implementation will be of great significance. We chose Jiangjin District(YQ-I), Tongliang District(YQ-II), and Liangping County(YQ-III), three demonstration counties of well-facilitied capital farmland construction from Chongqing Municipality as study areas, which were characterized by obvious gradient difference of agricultural industrialization.We also chose typical land consolidation projects as survey samples from each county. Taking economy and society effect as the core, and by the aid of entropy weight method and improved TOPSIS model, we built the post-evaluation index system and evaluated economy and society effect of three sample areas. In the evaluating index system, number of the new operators(C1), scale of land circulation(C2), area of scale management(C3), changes of peasants' annual farm income per person(C4), and changes of per area output(C5) were used as indicators of economy effect. Income of peasants' participation in the project(C6), number of peasants' participation in the project(C7), degree of peasants' satisfaction for the project implementation(C8), degree of peasants' participation late in the project(C9), and degree of nursing measures' implementation late in the project(C10) were used as indicators of society effect. The results showed that the index weight order of economy effect was C3(0.3984)>C2(0.2706)> C1(0.1798)>C5(0.1337)>C4(0.0175), and the index weight order of society effect was C9(0.4006)>C6(0.3999)>C8(0.0995)>C10(0.0919)> C7(0.0081). Through the classification of index weight importance, C3, C9, and C6 were classified as importance with the large variation and strong impact; C4, C8, C10, and C7 were classified as edge with the small variation and weak impact; the rest, as less importance with moderate impact. Evaluation results of the three study sample areas had an obvious relationship with the process of agricultural industrialization, order of the comprehensive effect was YQ-I(rapid advance)> YQ-II(accelerated advance)> YQ-III(relatively slow advance), and the effect level was good, medium, and poor respectively. And in single effect, there were disequilibrium features between economy effect and society effect, which included disequilibrium of index classification, effect classification, and the study sample area inside. However, accompanied by speeding up agricultural industrialization process, the gap between economy effect and society effect was closing from 22.25 times of YQ-III to 1.21 times of YQ-II, 0.77 times of YQ-I. Based on analysis of evaluation results, we considered that, in addition to following the generalized target, content and technical requirements, giving play to the supporting role of well-facilitied capital farmland construction in mountain and hilly area, should also definitely aim at practical demand of regional agricultural development. Among the three studied areas, experience of YQ-I was worth learning, and its specific practice consisted of three steps. First step was to discover regional advantages of agricultural resources and industry.Second step was to combine well-facilitied capital farmland construction with land circulation, agricultural industrialization and scale management.The third step was to transform farming plots, constructed supporting agricultural infrastructure according to demands of different agricultural industries and moderate scale management. By means of the three steps, YQ-I answeredthe needed-facilitied capital farmland construction on how to improve agricultural production conditions, and how to construct agricultural infrastructure, especially realized benign interaction between farmland construction and agricultural industrialization. However, problem of YQ-II still needed to rethink. The key was to pay more attention to new agricultural operators' role in well-facilitied capital farmland construction, and built a mechanism from point-based nursing experiences and succeeded practice to surface-based popularization and application. Lessons of YQ-III should be remembered. Well-facilitied capital farmland construction cannot be divorced from agricultural industrialization, and removed from agricultural structure adjustment, land circulation, moderate scale management, and new operators' development. In conclusion, under the guide of agricultural industrialization mountain and hilly area can be able to effectively utilize the supporting role of well-facilitied capital farmland construction, and realized better successor-nursing by means of new operators. Meanwhile, the evaluation method based on entropy weight method and improved TOPSIS model can be also effectively used to evaluate economy and society effect of well-facilitied capital farmland construction.
