Reducing the number of variables in the model, as far as it is possible to eliminate the defect of insufficient sample size, thereby improving the model fitting. Then introduce the logistic model, and analysis the results of regression.The fifth part is pointed out the problem and put forward some suggestions.This research methods:questionnaire, logic analysis, econometric analysis.The innovative points in this paper:the data is getting in the way of field visits and online questionnaire, it can response to the local people's real intention rather than getting from the data acquisition, the data will be more representative.
