The emergence of Vladivostok as a commercial port: US versus Japanese development

The Russian port of Vladivostok, closed to foreigners since before the Second World War, hsa been opened to foreign commerce by the government of the newly-created Russian Rupublic. Although the port faces many difficulties in establishing itself, many nations, Japn and the United States included, believe that Vladivostok will become a major centre to commerce between Russian and other Pacific nations. This article examine; (1) problems facing Vladivostok and the Russian Far Eatern Ports, (2) recent cargo throughputs and potential for growth, (3) investements by Japanese and United States corporations, (4) recent policy of the Japanese and United States governments regarding economic aid and cooperation with Russia. By analysing these data, it is possible to test the hypothesis that because of Japn' geographic advantage, its reliance on imports of raw materials that could easily be supplied by Russia,and its pre-eminence as an economic power in the region, Japnese corporation will become the major economic force in the development of the Russian Far East and the Port of Vladivostok in particular.

A global view on port state control: econometric analysis of the differences across port state control regimes

This article is based on 183 819 port state control inspections from various port state control regimes for the time frame 1999 to 2004. Using binary logistic regression, we establish the differences of port state control inspections across several regimes, even though theory predicts there should be no significant differences in treatments of vessels. The results indicate that the differences towards the probability of detention are merely reflected by the differences in port states and the treatment of deficiencies and not necessarily by age, size, flag, class or owner as perceived by the industry and regulators. The analysis further shows that some differences can be found across ship types and regimes and that there appears to be room for further harmonization in the area of port state control.

On the beaten track: a view of US West-Coast container port competition

More than a century ago far-sighted railroad builders and steamship operators were seeking the shortest intermodal itineraries between the eastern United States and the Orient. A combination of locational fact and the factual outcomes of 19th century railroad building left Chicago roughly equidistant in railway mileage from what became the four great US West-Coast port complexes in the Los Angeles, San Francisco, Portland and Seattle regions. Their nearly equivalent rail access to Chicago and points east has renewed significance in the container era.

This paper concerns the efforts of US Pacific seaboard ports to stay 'on the beaten track' with respect to container shipments between Asia and the eastern United States. The West-Coast ports are transit points dividing the transcontinental and transoceanic segments of long intercontinental journeys. From origins to destinations there are, in fact, many possibly feasible itineraries, including all-water routes.

The West-Coast ports have considerable control over their own site improvements. On the other hand, with respect to transiting container traffic, the ports may influence, but are unlikely to control, their own situations. Since the major container port facilities are very often on long-term lease to large intermodal carriers, the latter are making the important shipping and routeing decisions. The carriers tend in fact to set the tone and level of port competition.

What is the nature of the competition between container ports? Is it a figment of the publicist's imagination and perpetuated by irrelevant statistical boasting? Is it perhaps something forced on the ports by carriers eager to play one port off against another in a 'lowest bid' game? At what geographical scale might port competition be most useful or, maybe, least wasteful?     

Illusion as a factor in determining policy in development of a port: the case of Haifa

The mayor and citizens of Haifa live under the illusion that their city port possesses geographical advantages over competitor-ports, an attitude which gives rise to great hopes for the city's prosperity, especially after the peace agreement with Egypt.

On the basis of this illusion, decisions are made that may have severe consequences for the development of the port and the city. The aim of this article is to demonstrate that the changes in the Middle East over the years have deprived Haifa of most of the geographical advantages it had, and so expose the illusion for what it is.

Container port systems in China and the USA: a comparative study

This study compares the evolution of container port systems in China and the USA in terms of port throughput, number of container ports and the concentration level in the container port system, based on the time-series data on these three features over the period 1979–2009 for China and 1970–2009 for the USA. The results show that the densities of container ports in the two countries are similar, and their evolutionary processes are alike, which has led to a comparable market structure in the port industries of the two countries. In addition, the disparities between container ports closely represent the unevenness in the regional economic development. We further compare the port management regimes of the two countries in terms of the administrative processes for port development and expansion, the ownership structure and the providers of port functions, which offer some explanation on the dynamics of port evolution in the two countries. In conclusion, it can be seen that the evolution of the container port system and the management regime in the USA can be a de facto reference for the future development of the Chinese container port system.

The UNCTAD and WORKPORT models of port development: evolution or revolution?

Around ten years have elapsed since the UNCTAD model on port development was put forward as an explanation of how ports have adapted to incorporate technological, political and operational changes. The UNCTAD Three Generation Port Model is critically examined in the light of research carried out under the WORKPORT project funded by the European Commission, 1998-1999. Evidence from the WORKPORT study shows that, rather than developing in discrete steps, ports evolve continuously, adapting to new technologies, fresh legislation, revised working practices and other influences on an as-required basis. Further, it is demonstrated that several streams of evolution can be observed simultaneously; the pace of change within each stream can vary substantially. One of the prominent features of ports is that they often have several terminals, some operating along traditional lines while others may be leading edge in terms of technology, working practices or other aspects; all of them may be equally effective. The UNCTAD model, implying ports develop in discrete steps, or generations, is therefore shown to be fundamentally flawed.
