| Literatures about agricultural production efficiency are reviewed. Concept of DEA Method, as well as the definition methods of effective DEA and scale efficiency increase is introduced. According to the relevant statistical data in the years 1997-2007 in Chongqing Municipality, efficiency of agricultural economy is calculated from the year 1997 to 2007 by DEA method and the scale efficiency is also analyzed by taking the total output of agriculture, forestry, animal husbandry and fishery industry as the output index. And the input index includes total workforce in agriculture, forestry, animal husbandry and fishery, the total sown area of crops, the total power of agricultural machinery, chemical fertilizer application, the draft animal, and the effective... |

| Recently, several studies compared the performance of conventional and organic farms. Most studies concentrated on technical efficiency. In this paper we add to this literature by also comparing the scale efficiency of conventional and organic milk farms in Austria during the period 1997-2002. To do so we utilize a bilateral production frontier that includes both production technologies and Green’s (1995a,b) true fixed effects model to account for firm specific time-invariant heterogeneity and technical inefficiency. We find both groups of farms to be on average equally technical efficient (when compared to their production frontier), but conventional farms being on average considerably more scale efficient. However, while scale efficiency remained... |

| This study employed data envelopment analysis (DEA) to evaluate the comparative efficiency performance of selected commercial banks, rural financial institutions and microfinance institutions in China. The first pairwise comparison indicated that commercial banks achieved higher level of overall technical efficiency, pure technical efficiency and scale efficiency than rural financial institutions (including RCCs) through the study period (2004-2007). Overall technical inefficiency seems to be more attributed to scale inefficiency rather than pure technical inefficiency for both commercial banks and rural financial institutions. The second pairwise comparison indicated that RCCs and CFPA are the most efficient institutions with efficiency scores of 1... |
