Multi index comprehensive evaluation of sustainable development level of agricultural economy under the economic new normal

Aiming at the problems of low coupling degree of evaluation indicators and insufficient coordination degree of evaluation results in the existing evaluation methods of economic development level, this paper proposes a new evaluation method of sustainable development level of agricultural economy based on the research background of the new normal of economy. Firstly, construct an evaluation index system. Then, construct a judgement matrix for sustainable development of agricultural economy and calculate the weight of indicators; finally, the Data envelopment analysis (DEA) method is used to fuse the preset evaluation indicators and build a comprehensive evaluation model to achieve a multi indicator comprehensive evaluation of the sustainable development level of agricultural economy under the economic new normal. The experimental results show that the highest coupling degree of evaluation data for this method can reach 0.70, and the coordination degree of evaluation results is close to 1.0, indicating that this method effectively achieves the design expectations.
