摘要：We analyse the impacts of the CAP reforms on the technical efficiency of the crop farms. We use an output distance function and an inefficiency effects model which incorporates the influences of exogenous variables on farm efficiency. We formulate policy variables (e.g. the CAP subsidies) and producer characteristics as explanatory variables in the inefficiency effects model. We use the 1995- 2004 FADN data to estimate the production frontiers of the crop farms in Germany, Netherlands and Sweden, to derive their technical efficiency, and to determine the effects of the explanatory variables. The study shows that the 10-year average technical efficiency of crop farms is 59% in Germany, 75% in Netherlands, and 70% in Sweden. The average annual technical efficiency change is 0.1%, 0.7% and 2.7% respectively for Germany, Netherlands and Sweden.
