本文使用固定贝叶斯前沿模型和随机贝叶斯前沿模型对日本蒸汽发电企业的成本效率进行了分析和比较。我们表明，在对能源公司的业绩进行建模时，考虑异质性是至关重要的。模型估计的结果还表明，限制二氧化碳排放可以导致总成本的下降。这项研究最后讨论了被分析的能源公司之间的效率差异，并阐述了结果的管理和政策含义。
This study analyses and compares the cost efficiency of Japanese steam power generation companies using the fixed and random Bayesian frontier models. We show that it is essential to account for heterogeneity in modelling the performance of energy companies. Results from the model estimation also indicate that restricting CO2emissions can lead to a decrease in total cost. The study finally discusses the efficiency variations between the energy companies under analysis, and elaborates on the managerial and policy implications of the results.
