A Method of Economic System Efficiency Measurement: Taking the Chinese Farmland System Efficiency as an Example

It is very important to measure the efficiency of economic system. For lack of efficient means, we have made little progress in this aspect. On the basis of historical fact measurement model, together with the method of the counter-historical fact, this article carries on the measurement and the comparative analysis on the farmland system efficiency since 1949, and discovers the big difference among the efficiency in implementing the three farmland systems. This method may provide the reference for the research on other system efficiency.
