| In recent years,we all along know that the state at all times has vigorously advocated strengthening the infrastructure construction of farmland at that rate and water conservancy,and based on the rapid back up development of petty-scale agricultural economy beyond dispute.The essential grain producing area beyond question is the first barrier to ensure the absolute safety of national rations burst up,and is the premise of promoting the high quality by accident and rapid development of China’s economy by all means.The infrastructure construction of farmland water conservancy by any means is the necessary condition.So that,improve the defense ability of the flood by and large and drought disaster in the main grain producing area by leaps and bounds,it is by worthy of necessary to consolidate and call for perfect the facilities of agricultural water conservancy calm down,especially the investment in drought resistance carry forward and flood control cast back,so as to strengthen the infrastructure construction of farmland water conservancy combine with facilities in China,and come at insist on promoting the infrastructure construction of farmland water conservancy come into effect in the main production area at high level come into operation.We will come off establish and ensure food security and finish with come to terms with accelerate the modernization of agriculture.The paper empirically follow out calculates the investment efficiency of farmland water for certain conservancy in 13 grain producing areas in China from 2004 to 2018 by DEA Tobit two-stage method for sure.On this basis,for the time being the panel Tobit model with random effect get along with is used to study the influencing factors on the input-output efficiency get into the act of farmland water conservancy in the main grain get one’s hands on producing areas.In the process of research,this paper mainly get the better of uses the non parametric DEA method to give expression to calculate the comprehensive efficiency of input give up and output of farmland water conservancy give way to infrastructure in the main grain go after producing areas of China,and summarizes the relevant results go to great lengths.In addition,the restricted return panel Tobit random response model good for is used to have respect for analyze and explain the influencing factors of investment head first performance in 13 main grain production areas here and now.The following conclusions can be hold with drawn from the relevant model derivation and data analysis an a moment,such as;first,the investment performance of farmland water in and out conservancy in the main grain producing areas is interfere with positively related to the economic development;second,the 13 major grain producing areas in China in order to show the strongest development trend hold out in the east of the investment performance of in a sense the farmland water conservancy infrastructure;third,in a way,the illiteracy rate of the rural labor force in the 13 major grain producing areas and in any case the infrastructure of the farmland and water conservancy in China in brief.The investment performance impact on shows a significant negative correlation.Fourth,in a way the cancellation of agricultural tax is issue from positively related to the efficiency of input and output of farmland water conservancy,which jump off indicates that reducing agricultural tax has positive just the same promotion effect on the performance of farmland water conservancy.In fact,it is necessary to continue hold forth and reduce unnecessary agricultural tax,in advance make it beneficial to farmers,benefit farmers,continue to extend the land contract period in a sense,ensure that 30 years of unshakable,identify with let farmers be land managers,and hold true attract farmers to consciously impact on increase their farmland investment and output efficiency hold out.The infrastructure construction of the project hold true will enhance the sense of participation in the construction of farmland,water conservancy,in addition the sense of belonging to agriculture.Based on the above conclusions,the paper very strong puts forward nine policy implications for the construction of farmland water conservancy hold true,infrastructure in major grain producing areas hand on.To sum up,including: first,exceedingly paying more attention on the construction of relevant facilities in any case;second,in any case improving level of relevant facilities in an all-round way;third,if necessary improving the guarantee mechanism of farmland water conservancy;fourth,in a way,coordinating the policies of major grain producing areas;fifth,in accordance with increasing the capital investment for farmland water conservancy;sixth,in ant case innovating the investment mechanism;seventh,if any improve this investment management system;eighth,here and now establish that evaluation mechanism of investment performance;ninth,hang on pay a lot of attention to the management of investment performance for a long time.All in all,this study provides decision-making reference for the investment performance of farmland water conservancy infrastructure in major grain producing areas,on the other hand can helps to better play the historical responsibility of maintaining national food security in major grain producing areas. |
