These aspects are equivalent to public products. Just because of this, it leads to problems that nobody will not control. The governments, in order to realize regional economic coordinated development and to eliminate the regional interests parties of administrative regions economy in microcosmic, were adapting various self-protection measures, even including that "you may have your policy but I have my countermeasures" that is derived from inter-regional economic relations. The action of market segmentation has limited the flow of various economic development elements, especially the condition of "dead end highway", resource exploitation and use, difficult social security work in social living of the administrative boundary zone. This paper studies the typical economical district of Wuling mountain area in the obvious strategic position at the junction of Chongqing, Guizhou, Hunan, Hubei provinces from the angle of regional public management and public choice to present issue awareness and academic purpose.展开更多

There are mainly four types of free economic region, that is, commercial type of free economic region —free port, industrial type of free economic region — export processing area, integrated commercial and trade type of free economic region — free trade zone, and scientific and technological type of free economic region — scientific industrial park. With the development of free economic region of different countries, besides free economic region within one country, there appear transnational border free economic region established by two or multiple countries. Analysing favorable factors and unfavorable factors to establish the free economic region for China and Russia, for example, China and Russia have land boundary line of 4282.7 km; China and Russia may strengthen overall cooperation in politics, military, economy, science and technology, culture, etc. making full use of geographical factors of the two countries, borders; there is a strong complementarity in resources, labour force etc. for China and Russia; strengthening the Sino Russian economic trade cooperation is needed, the authors proposed a conception and selected four comparative ideal locations for establishing the Sino Russian border free economic region: Manzhouli Zabaikalye Free Economic Region, Heihe Blagoveshchensk Free Economic Region, Suifenhe Pogranichnyy Free Economic Region, Hunchun Hasan Free Economic Region. Finally the principles and patterns for establishing free economic region are discussed.展开更多

Diisononylphthalate (DINP), diethylhexylphthalate (DEHP), dibutylphthalate (DBP), diisododecylphthalate (DIDP) and 4-nonylphenol (4-NP) were oestrogenic in the yeast estrogen screen (YES) assay and potently oestrogenic in the MVLN and E-SCREEN assays at environmentally relevant concentrations. DINP and 4-NP were mutagenic in the Ames assay and also induced significant levels of unscheduled DNA synthesis and DNA strand breakage. Significant induction in the percentage of cells containing micronuclei was observed after treatment with DINP, DEHP and 4-NP. In addition, sewage effluents from sewage treatment plants (STPs) in the Border, Midlands and Western (BMW) region of Ireland were significantly oestrogenic in the YES assay. Moreover, analysis of levels of phthalates and alkylphenol identified in Irish rivers receiving treated effluent showed potent oestrogenicity in the YES assay. The proliferative and genotoxic ability of the phthalates and alkylphenol, and the oestrogenicity of the treated effluents reported here, is significant as these EDCs and EDCs within the effluent may play a role in the etiology of human abnormalities.展开更多

In this paper, a methodological study in relation to the sustainable development of cross-border regions is conducted. Our particular interest focuses on the locational characteristics of cross-border regions as well as their economic implications to the cross-border governments. Based on a sustainable development model from which the optimal outputs of different kinds of border-regions can be derived, we try to methodologically help cross-border governments to reach a final agreement of sustainable development of natural and environmental resources.It is concluded that the methods by which the net benefits among the sub-regions can be redistributed may be: 1) to equalize the absolute values of net benefit among all sub-regions concerned; and 2) to equalize the relative values of net benefit among all sub-regions concerned.展开更多

Using the model in this paper, we present a quantitative method to calculate the economic impacts of 'provincial borders' and apply it to the border-region of Shanxi, Hebei, Shangdong, and Henan provinces. The result shows that the economic potential in the border-region hasnot been efficiently exploited and that the annual gross agricultural products have decreased by 10.4% due to the 4-p borders.展开更多

The results show that: (1) the principal compressional stress of the stress field is oriented in NW-SE direction and the principal extensional stress is in NE-SW direction; (2) the WNW-ward compression and collision of the Philippine Sea Plate to the eastern coast of Taiwan Island are the most direct and most important dynamic source for preparation and occurrence of strong earthquakes in the Taiwan Region and along the border zone between Fujian, Guangdong and Jiangxi Provinces.展开更多
