项目摘要

This study aims to analyze efficiency and productivity of the Japanese economy using new techniques to uncover why the Japanese economy stagnated so long during the 1990s. A standard method of total factor productivity is not adequate for this purpose because it assumes that no inefficiency exists. Most previous studies of efficiency analysis on the Japanese economy are also unsatisfactory because they focus on measurement of technical efficiency and ignore allocative efficiency. We measure allocative efficiency jointly with technical one so that the impacts of resource distortions on cost and productivity axe evaluated. Kumbhamar and Wang (2006), J. of Economet, 419-440, already estimate the translog distance function model incorporating both allocative and technical efficiencies. We extend this model by exploiting a conversion equation between input and output distance functions, which simplifies the nonlinear programming problem measuring the optimal levels of inputs. Based on this analytical framework, three empirical studies are conducted. Firstly regional macro economy is analyzed with a panel data on 47 social prefectural account. The result shows that allocative inefficiency of the Japanese economy started to improve accompanied by rapid labor adjustment since Heisei financial crisis 1997. Secondly, the transmission-dist: elution electricity is examined with a panel on nine Japanese electric utilities. This study shows that the cost efficiency was continuously improved during the late 1990s that coincide with the startup of the regulatory reform. Thirdly solid waste management activity is analyzed to evaluate productivity and efficiency of the public sector. The results show that our efficiency analysis is promising as a benchmarking tool for public sector

这项研究旨在使用新技术来分析日本经济的效率和生产力，以发现为什么日本经济在1990年代这么长的时间停滞不前。总体因素生产率的标准方法对于此目的不足，因为它假定不存在效率低下。先前对日本经济效率分析的大多数研究也不令人满意，因为它们专注于测量技术效率并忽略了分配效率。我们与技术共同衡量分配效率，以使资源扭曲对评估成本和生产力轴的影响。 Kumbhamar and Wang（2006），J. of Conance，419-440，已经估计了纳入分配和技术效率的Translog距离函数模型。我们通过利用输入和输出距离功能之间的转换方程来扩展此模型，这简化了测量最佳输入级别的非线性编程问题。基于此分析框架，进行了三项经验研究。首先，通过47个社会县帐户的小组数据对区域宏观经济进行了分析。结果表明，自1997年海塞金融危机以来，日本经济的分配效率低下开始伴随着迅速的劳动调整。其次，通过九个日本电力公用事业的面板检查了传输量：洗脱电力。这项研究表明，在1990年代后期，成本效率与监管改革的创业相吻合。第三，分析了固体废物管理活动，以评估公共部门的生产力和效率。结果表明，我们的效率分析作为公共部门的基准工具有希望
