LevelofcoordinateddevelopmentofurbangrowthpoleinYangtzeRiverDeltaregionofChina/WANG Baoqian, et al (Institute of Technical Innovation & Economic Development, Hohai University, Nanjing 211100, China)

Abstract: Empirical researches on the level of coordinated development of growth pole of 16 cities in the Yangtze River Delta region during 2007-2011 are performed by using the method of factor analysis. The results show that the deviations of economic, social, environmental and comprehensive indices are respectively 1.821,-0.096, 0.743 and 1.373, and their peak values are respectively 3.618,-0.722,-0.774 and 1.607, indicating that the difference of urban growth pole in the Yangtze River Delta region comes mainly from that of economic development level, and the small differences of social and environmental development levels are in favor of reducing the difference of the comprehensive development level in the Yangtze River Delta region. Therefore, maintaining the existing polarization system, the cities in the Yangtze River Delta region should combine with its own resources and historical accumulation to promote the free flow of factors and to raise the coordinated development level.

Financialevaluationofwateraffaircompaniesbasedonintegratedweightingmethod/WANG Huizi, et al (Business School, Hohai University, Nanjing 211100, China)

Abstract: With regard to the characteristics of water affair companies and the existing problems in their financial evaluation, a financial evaluation index system is established. An evaluation model for the comprehensive financial evaluation of water affair companies is proposed by using the entropy method and AHP method to assign the integrated weight. Four listed water affair companies in China are selected to be empirically analyzed. The results show that the operating management capability, financing capacity, local government policy support, ability to integrate acquisitions and innovation capacity of the water affair companies are also the important indices. It is suggested that the regional water affair companies should merge the inter-regional assets to realize their role as the national water affair group.

EstimationofpotentialtransactionscaleofwaterrightbetweenindustrialandagriculturalsectorsinQingdaoCity/SUN Jiangyong, et al (College of Economics and Management, Shandong University of Science and Technology, Qingdao 266590, China)

Abstract: The production function of the industrial and agricultural sectors is estimated by using their panel data of 17 cities in Shandong Province from 2007 to 2011. The potential transaction scale of water right between the two sectors is measured by means of the estimated parametric values of the production function. The results show that the water resources have significant effect on the production of both the industrial and agricultural sectors. The smaller the marginal revenue difference between the two sectors under water right transaction equilibrium, the larger the potential transaction scale of water right. The potential transaction scale of water right generally increases during the period from 2007 to 2011.

Warningofurbanextremerainstormflooddisastersbasedoncloudmodel/WANG He, et al (State Key Laboratory of Hydrology-Water Resources and Hydraulic Engineering, Hohai University, Nanjing 210098, China; Institute of Management Science, Hohai University, Nanjing 211100, China)

Abstract: By dividing the city into a number of relatively independent areas using the two-dimensional graph theory clustering method and creating four corresponding levels of normal cloud according to the actual situation of each individual region and a unified extreme rainfall flood disaster risk level, a warning model for the urban extreme rainstorm flood disasters is established based on the cloud model. It is employed to conduct dynamic warning of rainstorm flood disasters in Jingdezhen induced by the same rainfall in different areas and the rainfall during different periods in the same area. The results show that when the extreme storm comes, the west and east districts and Fuliang County of Jingdezhen suffer from a higher level risk of loss, and the level rises from grade Ⅲ to Ⅳ with the elapse of time, but Dianchang area and Lümeng Air area suffer from a lower level risk of loss, and the highest level is not larger than grade Ⅲ. The real-time and accurate dynamic warning for disaster levels of various regions in Jingdezhen during different periods are performed by means of the cloud model.

Resettlementgoalforhydropowerprojects:policyandreality/YAN Fengxia, et al (School of Public Administration, Hohai University, Nanjing 210098, China)

Abstract: The evolvement processes of resettlement goals and resource allocation patterns in China are reviewed. Combined with the development practice of ZJ resettlement village of Danjiangkou Reservoir, it is pointed out that the realization of the development goal of resettlement is mainly influenced by the allocation pattern of governmental resources, development conception of local governments, practical ability of communities and development capacity of immigrants. The lagging of any of the above factors may lead to deviation from the development goal. To avoid the development trap of resettlement, the following measures should be adopted: change of development conception, improvement of allocation patterns of resources, cultivation of community elites, strengthening of immigrants’ participation and mobilization of immigrants’ enthusiasm.
