Analysis on the Sales Effectiveness of Pollution-Free Food in China

摘要

Based on the past research methods, the paper puts forward the Data Envelopment Analysis (DEA) method to assess whether a number of input variable and output variable of pollution-free food are relatively efficient or not. This method can be used not only for the assessing method of economic efficiency but also for social efficiency. The paper makes the each phase as input indexes, such as the number of pollution-free food enterprises, pollution-free food products, area of origin monitoring,physical volume,annual exports and per capita disposable income. Then the pollution-free food annual sales can be selected as output index. By studying the efficiency development of Chinese pollution-free food from the year 1996 to 2007, we conclude that the sales quality of Chinese pollution-free food is in effective state for most of the years.
