英文文献摘要：
Use of efficiency measures as a proxy for performance to test the market structure-conduct-performance (SCP) hypothesis is explored. Utilizing Battese and Coelli specification, we estimate stochastic frontier production function and SCP equations with output and efficiency measures as endogenous variables. An empirical application to U.S. trucking carries over the period 1994-2003 with emphasis on the agricultural commodity and refrigerated food products carriers is examined. Results reveal that the variables average haul, average load and market concentration significantly affected the efficiency of firms with 2-8 number of years within each firm.
本文探讨了利用效率指标作为绩效指标来检验市场结构-行为-绩效(SCP)假设。利用Battese和Coelli规范，我们估计了以产出和效率度量为内生变量的随机前沿生产函数和SCP方程。1994-2003年期间，以农业商品和冷藏食品运输为重点，对美国卡车运输的实证应用进行了研究。结果表明，平均运力、平均负荷和市场集中度对2-8年的企业效率有显著影响。
