First, I want to make it clear the source of competitiveness of Japanese main container ports. Second, I will specify the course of suitable container port policy in Japan. In general, there are three sources of competitiveness of container ports, that is, industrial agglomeration and volume of cargoes as the result of it, supply chain networks, especially, networks of shipping lines and stevedoring system in container port. Now, Japanese main container ports have lost the first source of competitiveness of container ports, namely, volume of cargoes and networks of shipping lines of these ports are weakening. The result clearly show that Japanese main container ports can not depend to increase container cargoes throughput on only efficient stevedoring system in port as the third source of competitiveness of container port. Therefore, Japanese government should, at first, support to strengthen supply chain networks as short-term policy and secondly promote to reagglomerate or regenerate the cluster of manufacturing industry as long-term policy.

岡山大学経済学会 Acta Medica Okayama 0386-3069 42 4 2011 中日経済の多部門計量モデルの枠組み−中国多部門モデルの検討を中心として− 17 39 EN Jian Teng 10.18926/OER/44387 This research aims to clearly illustrate the economic growth and changes in the industrial structures of both China and Japan, as well as the dependence relationship between the two countries and the impact that their trade and foreign direct investment (FDI) have on their respective economies. It also intends to develop a multisectoral econometric model of China-Japan economic relations designed to work out policy simulations and future prospects. In traditional multi-sectoral econometric models, approaches have been adopted in such a manner that makes the macro-econometric model of each country multi-sectoral under the framework of inputoutput analysis, making such a multi-sectoral econometric model duly linked by means of the international trade model. This research is based on the understanding that an international input-output table can describe the dependence relationship of each country most commensurately, and therefore attempts the method from the start where the macro-econometric model of each country should be made multi-sectoral under the framework of international input-output analysis. In addition, many earlier studies have estimated time-series information such as input coefficients or expenditure coefficients of final demand by implementing various measures based on the information from a nation's input-output table as of a specific point in time or as of the bench mark year. In this research, we intend to establish time-series China-Japan international input-output tables by means of Economate I-O and later utilize the original database. Furthermore, in this research that aims to develop a China-Japan multi-sectoral econometric model, because the accumulation of research achievements on China lags far behind when compared to Japan, we are going to examine, on a priority basis, the theoretical framework and equation of the models, primarily focusing on China’s multi-sectoral model.

This paper considers the relationship between vertical product differentiation and labor-managed firms in either partial or full market coverage by using a two-stage game model. At the second stage they are involved in either Bertrand or Cournot competition. Then some results, which are different from those derived from the conventional firms, are obtained. For example, 1) when labor-managed firms are involved in price competition in an output market, there exists an interior solution only in an extremely limited case; 2) fixed costs affect not only price and output levels but also the level of quality under both price and quantity competition; and 3) it is impossible to analyze under full market coverage, irrespective of whether labor-managed firms are involved in price or quantity competition in an output market.
