本研究的主要目的是评估竞争因素是否会影响成本降低或TFP增长，即使所有权由公共部门保留。为了进行实证研究，我们选择了日本的包裹递送市场。1976年，邮政局垄断了包裹递送市场，私营大和公司的进入极大地影响了包裹递送市场，邮政局的份额开始下降，到1998年仅为14.9%。在这项研究中，我们估计的货物运输的总成本函数，通过使用一个汇集的数据集，和享乐规格的输出制定，以考虑输出特性。我们的结论是，竞争有助于私营公司的成本降低和TFP增长，而不是在邮政署的情况下。
The main purpose of this study is to evaluate whether the competition factor affects cost reduction or TFP growth, even when ownership is maintained by the public sector. For empirical investigation, we selected the parcel delivery market in Japan. Formerly monopolized by the Post Office, the parcel delivery market was dramatically affected by the entry of the privately owned Yamato in 1976, an event which saw the share of the Post Office begin its decline to only 14.9% by 1998. In this study, we estimate the total cost function of goods transported by using a pooled data set, and the hedonic specification of output is formulated in order to consider output characteristics. Our conclusion is that competition has contributed to cost reduction and TFP growth in the case of private companies but not in the case of the Post Office.
