According to the index system of\""four forces\""，this paper selects 15 economic variables such as industrial policy and labor cost.To test the quality of the data used in this paper，we observe the basic characteristics of each variable and eliminate the impact of the abnormal data on subsequent analysis.Table 3 reports the descriptive statistical re-sults of the main variables.There is obvious incompatibility among the indexes，and direct calculation will lead to the distortion of the evaluation results.Therefore，the necessary data processing willfollow.First，the inverse index is converted into positive index by reciprocal method，and then the averaging method is used.Although there is a lot of literature using the normalization method，the average value of each index after normalization is 0，and the standard deviation is 1，so it is difficult to compare the variation degree among the indexes.The averaging method not only retains the difference of the degree of variation of indexes，but also contains the information of the difference of the degree of influence of indexes，and the dimensionless processing is performed on the indexes.The original data mainly come from China Statistical Yearbook，China Rural Statistical Yearbook，China Agricultural Statistical Yearbook，China Science and Technology Statistical Yearbook，International Statistical Yearbook，China Foreign Trade Statistical Yearbook，Hunan Province Statistical Yearbook，Hunan Science and Technology Statistical Yearbook，and Wind database from 2001 to 2014.For partial default data，the mean value is used instead.
