Empirical quantitative analysis on risk level of vegetable industry in China

ObjectiveThe yield risk,price risk and earning risk of whole vegetable industry and typical varieties of vegetable were estimated in order to provide reference for government administration and the main body of vegetable pro-duction and management to make decisions on cultivation and management.MethodMobile coefficient of variation was selected as risk measurement index. The historical production and price data of vegetables in different varieties and plan-ting patterns of vegetable industry in China over the past years were used to conduct empirical quantitative analysis on the risk level of vegetable industry.ResultThe earning risk and price risk of vegetable industry were higher than yield risk. There were significant differences in the risk level among different varieties of vegetable. According to the categories of plating pattern,the risk level of facility vegetable was greatly lower than that of open-field vegetable.SuggestionBased on the risk level measurement results of vegetable industry,the varieties and patterns of vegetable planting should be ratio-nally redistributed in order to make sure that the incomes of the main body of vegetable production and management steadily increase,and the market structure keeps balance,and realize the effective supply for vegetable market.
