An analysis of the overcapacity problem under the decentralized management system of container ports in Japan

Abstract

This article is concerned with an analytical summary of how the Japanese container ports have been taking place overcapacity problem in a systematic way. It focuses on institutional aspects of the overcapacity problem from the viewpoint of accounting cost and opportunity cost. The first issue arises due to the port authority's accounting system and insufficient disclosures of financial statements of port business to the port users and taxpayers. The second issue is inherently related to resource allocation between the state government and local governments through the budget system and income distribution programmes. Since a proper allocation of economic resources in the port sector as a whole will depend on investment decisions being taken within a coherent framework for ensuring that costs are passed on to port users, these issues are closely related to each other in reality. Although the budget system is completely controlled by the state government, the local governments have authoritative power over port planning, financing, and management, which is assured by the Ports and Harbours Law. The overcapacity problem appears to be an inevitable result.
