Technical efficiency and farm size: a conditional analysis
研究了技术效率与农场规模的关系，通过控制变量分析农场异质性的影响，并利用西班牙奶牛场面板数据进行了实证检验。
Abstract The relationship between technical efficiency and size might be affected by farm heterogeneity. We analyse this relationship conditional on a set of control variables. These control variables are chosen using a production model where technical efficiency is introduced as a parameter. As a result, technical efficiency affects both the input demand and the output supply of a profit maximising producer. The empirical application explores these issues using panel data of dairy farms in Spain.
