Abstract:After the evaluation index of growth performance of grain family farm is theoretically screened based on the new concept of development,this paper screens the above index with the help of expert evaluation and discrimination analysis and constructs a system of evaluation index with a high score creditability and validity. Then,based on the sample of 453 grain family farms in five provinces of North China Plain,this paper studies the index system by using the analytic hierarchy process and fuzzy integrated evaluation. The result shows that although the growth performance of grain family farm is in the moderate upward level as a whole,there are still some differences of growth performance among individuals. Economic performance generally is good,but the innovation performance is relatively low. Therefore,it is necessary to guide the balanced development of family farm,make precise supporting strategies and establish the monitoring system of growth performance.
