Northeast Asia with China ,Japan and South Korea as the main components has drawn more and more atten-tion worldwide.Many scholars have researchec on the prospect of some alternatives of regional economic integration in Northeast Asia/or Yellow Sea Rin as its core area.In this paper the authors start with an introduction of the major arguments embracing Yellow Sea Rim regionalism,and attemptto identify the dynamics challenging the proposed approach-es of sub-regionalism of Northeast Asia.The paper firstly gives a brief review on the undate development of bilateral econom-ic exchanges,mainly Sino-Japanese and Sino-South Korean trades and direct investments with related contemporary is-sues.When the changing pattern of economic interactions is analyzed,special concerns are given to the possibility to real-ize the supposed potential of regional economic cooperation mainly based on economic complementarity among the related regions of China ,North Korea,South Korea,and Japan.The authors then made their major efforts on putting forward possible approaches of multilateral cooperation of three countries in the near future,that is ,deepened cooperation in select-ed sectors of industry and transportation and coordinated development among major cities.The authors stress that the develop-ment of sub-regional sectoral cooperation and the formation of interactive network of city-regions via social and economic interactions at local level are significant to the future regional integrated development in Northeast Asia.. 相似文献

The economic growth of China has led to increasing growth disparities between regions. Such disparities are uncontrolled and are severely negative symptoms in the process of economic development. On the basis of system dynamics （SD） modeling and the rela- tionship between industrial relocation and regional economic growth, we construct a model of the interrelationship between the two aforementioned phenomena. The model is an effective and creative exploration for examining effects of industrial relocation on Chinese regional economic growth disparities. The SD model is employed in this study to build an inter-regional labor migration SD model, an inter-regional capital migration SD model, an intra-industry SD model, an intra-regional population SD model, and an intra-regional SD model which are based on realities in labor and capital flow from the view of industrial relocation. VENSIM software is utilized to per- form a system simulation based on the data of the eastern, middle, and western regions from 2000 to 2010. Results show that indus- trial relocation gradually narrows the relative disparity in GDP among the three regions. Moreover, the absolute one is enlarged con- tinuously. The absolute and relative disparities in per capita GDP among eastern, middle, and western regions generally exhibit de- creasing trends. 相似文献

Taking the development of export-oriented economy (the strength and temporal sequence) as a main line, this paper discusses
and analyses the position and role of Wuhan, which is the biggest metropolis in the central China and the middle section of
the Changjiang (Yangtze) River basin, in the regional economic macro-strategy of China from a new visual sight. On the basis
of the background of a large economic triangle constructed by Hongkong, Wuhan and Shanghai, the paper discusses the relations
between Wuhan and Hongkong, Wuhan and Shanghai. The aim of the paper is to provide some new evidences for the development
of great regional economy of China under the copropelling of the three great economic pivots.

A regional multiple-objective water-resource and economic optimization model was developed using a quantitative method of systematic analysis.Input to the model includes indexes of economic structure and development,water-resource utilization,wastewater and pollutant discharge,and investment in wastewater treatment.The model,which consists of producton-structure and industrial-structure optimization modules,was applied to the Guanzhong region in the middle reaches of the Huanghe(Yellow) River basin in China.By evaluating several alternative production and industrialization schemes,the modal indicate that water pollution will get worsen though wastewater treatment improves if the economy continues to develop at the planned speed without structural adjustment.However,the results also show that not only economic goals but also water-resource protection and pollution-control targets can be achieved under an alternative,recommended production and industrial structure.This example illustrates that economic development and environmental protection can be improved coordinately by the regional multiple-objective water-resource and economic optimization model.It provides an operable approach to the simultaneous sustained development of water resources and economic growth. 相似文献

The economic system of mining city is of typical vulnerability characteristics that can be manifested by its high economic
sensitivity and lack of response capacity to the gradual depletion of regional mineral resources. Taking Fuxin City of Liaoning
Province as a case, this paper established an economic vulnerability assessment method integrating BP neural network with
vulnerability index, then carried out an economic vulnerability assessment of Fuxin during 1989–2006. The results indicate
that: 1) Affected by the gradual depletion of regional mineral resources, the economic development of Fuxin had kept high
economic sensitivity from 1995 to 2001, and the response capacity to cope with and adapt to the impacts of the perturbation
of mineral resources was weak and relatively lag. The evolution of economic vulnerability can be divided into three stages:
in 1989–1994, the economic vulnerability of Fuxin City decreased slowly; in 1995–2001, the beginning stage of economic transformation,
the economic vulnerability of Fuxin City went up rapidly; in 2002–2006, the economic vulnerability of Fuxin City descended
and showed a trend to be stable. 2) The influence of economic sensitivity on Fuxin’s economic vulnerability is more evident
than that of response capacity. 3) The decreasing supply of mineral resources and the simple industrial structure are main
factors leading to the economic sensitivity of Fuxin. 4) The improvement of economic response capacity of Fuxin has typical
characteristics of input-driven growth, and external assistance is of great importance to the rapid improvement of economic
response capacity of Fuxin. And 5) the change from the simple industrial structure to diversified one of Fuxin is still unaccomplished,
and the contribution of non-coal-based industry to local economic development is relatively limited.

This paper falls into the broad area of economic geography and economics of creativity,and it presents an alternative approach to explain why total factor productivity(TFP)growth is different across China′s regions.It establishes an empirical model to estimate the spatial agglomeration effects of creative industries on regional TFP growth,using China′s provincial panel data during the period of 2003 to 2010.We found that the creative industries agglomeration(CIA)has significant and positive impact on regional TFP growth.The result also implies that the CIA can facilitate regional TFP growth through promoting regional innovation instead of improving regional efficiency.Therefore,we argue that policy makers should take some measures to retain and establish more creative zones. 相似文献

Social capital has played an increasingly important role in regional development. China is a country with high stocks of social
capital. Using several different indicators of social capital, this study tries to research the regional disparities in social
capital and the influence of social capital on economic growth of China in 1978–2004. Measuring social capital with indicators
of associations, charities and blood donation rates, this study finds significant regional disparities in social capital at
provincial level in China. Those indicators for social capital are highly correlated with regional economic performance. Statistical
analysis shows that social capital has a significant and positive effect on a long-term provincial economic growth. This relationship
exists after controlling policy, macro location factors, and per capita GDP in the initial year. The empirical findings indicate
that institutions, culture and social relations are critical for regional development in China. Therefore, the creation and
support of social capital should be paid more attention to when making regional policy. 相似文献

The seven economic zones are multiple economic zones, with the characteristic of both long-range economic zone and categorical
economic zone. They are the transitional regions between the categorical economic zone and the comprehensive economic zone.
The phenomena of overlapping are only allowed to appear in categorical economic zones. The influence of Hongkong return back
to China should be considered when doing research on economic zones. Hongkong is the center of the southeastern coasts and
will become an offshore banking center of the mainland. According to the theory of economic zoning, the division of the whole
country into seven economic zones demonstrates the transitional nature clearly. With the further development of the economy,
the deeper maturity of the central cities and the stronger connection of the regional economy, the composite economic zones
will gradually turn into more integrated comprehensive economic zones. 相似文献

China is a country with a vast marine territory whose area covers one third of the total land territory area. With the exploitation
of marine resources and the development of marine economy, marine economic regions have been formed gradually. We shouldn’t
ignore them when we divide economic regions throughout the whole nation, especially in our country. In this paper, we’ Il
expand division principles, practice and methods of marine comprehensive economic region. Liaoning Province, facing the Yellow
Sea and the Bohai sea, is not only a part of Round-the-Bohai Sea Economic Region, but a part of national marine econemic region.
Through evaluating marine resources of Liaoning, and analyzing development of marine economy, composition of marine industries
and distributional characteristic of marine economy, Liaoning marine region is divided into Bohai Sea marine economic region
and Yellow Sea marine economic region based on differences of marine economy. Thereby we go further into the formation of
regional marine economic region and distributional mechanism of regional marine economy.

1INTRODUCTIONThere have been many literatures about the regional disparity of economic development in China since the late 1970s. Some scholars argue that disparity of re-gional development in China has been expanded since 1978, but others find it has reduced since 1978. The findings of some scholars show that the evolutionary process of the disparity of regional economic develop-ment in China follows the inverted U shape, but some others do not think so. What is the true tendency, and i… 相似文献
