    RelationshipbetweenenvironmentalregulationandtransformationofmanufacturingindustryinYangtzeRiverEconomicBeltunderinnovation-drivenbackground/HUANG Dechun1,2,3, MIAO Yijin1,3(1.Business School, Hohai University, Nanjing 211100, China; 2.Jiangsu Provincial Collaborative Innovation Center of World Water Valley and Water Ecological Civilization, Nanjing 211100, China; 3.Institute of Industrial Economics, Hohai University, Nanjing 211100, China)

    Abstract: Based on the mechanism of environmental regulation on the transformation of manufacturing industry under the innovation-driven background, the intermediary effect of innovation on the relationship between environmental regulation and manufacturing industry transformation is empirically studied using the panel data of 11 provinces and cities in the Yangtze River Economic Belt from 2005 to 2016. The results show that the effect of environmental regulation on the transformation of manufacturing industry has a double threshold effect under the innovation-driven background. In different ranges of innovation-driven background, the effect of environmental regulation on transformation of manufacturing industry has different directions and degrees. Therefore, attention should be paid to the synergy of innovation-driven background and environmental regulation, and the environmental regulation policies should be formulated according to local conditions. Simultaneously, the following measures should be taken to realize the transformation of manufacturing industry in the Yangtze River Economic Belt: rational allocation of fixed assets, increase of investment in education, guidance for the direction of financial expenditure, strict examination of the threshold of foreign investment access, and introduction of advanced technology.

    Keywords: environmental regulation; innovation-driven background; transformation of manufacturing industry; Yangtze River Economic Belt

    Relationshipamongnewurbanization,upgradationofindustrialstructureandwaterpollution/WANG Baoqian, ZHU Xilei(Business School, Hohai University, Nanjing 211100, China)

    Abstract: Based on the panel data of 9 provinces and 2 cities in the Yangtze River Economic Belt from 2008 to 2017, the decoupling-PVAR two-stage model is used to analyze the evolution trend and impact mechanism of the relationship among new urbanization, upgradation of industrial structure and water pollution. This study shows that: The relationship among water pollution, new urbanization, and industrial structure exhibits the evolutionary trend of “expansion negative decoupling-strong decoupling”, indicating that the urbanization and industrialization of the Yangtze River Economic Belt have experienced “pollution first, then governance” at this stage, but ultimately achieved the dual goals of economic development and water pollution improvement. The results of impulse response and variance decomposition indicate that the water pollution control effect of new urbanization at this stage is not obvious, there is a clear negative relationship between water pollution and upgradation of industrial structure, and the former has a stronger explanatory effect on the latter. The variances of the upper, middle and lower reaches of the Yangtze River Economic Belt are decomposed, respectively, and it is found that there are obvious regional differences in the degree of mutual influences between the variables. The prevention and control policies for water pollution should be formulated according to specific situations.

    Keywords: new urbanization; upgradation of industrial structure; water pollution; decoupling; PVAR

    Quantitativeanalysisofwatersupplybenefitsofinter-basinwaterdiversionprojects/FANG Guohua1, SONG Ziqi1, LIAO Tao2, WEN Xin1, LU Chenxuan1(1.College of Water Conservancy and Hydropower Engineering, Hohai University, Nanjing 210098, China; 2.Nanjing Branch, Jiangsu Surveying and Design Institute of Water Resources Co., Ltd., Nanjing 210029, China)

    Abstract: The inter-basin water diversion project is the most effective measure to solve the non-uniformly spatial and temporal distribution of water resources and the uneven water demand of society. According to the characteristics of inter-basin water transfer projects such as involvement in different basins, multi-function, complicated structure and intersection with the local drainage, a method for quantitative analysis of water supply benefits of inter-basin water diversion projects is put forward. In accordance with the structure of water supply, the water supply benefits of the domestic living and the three main industries are quantitatively calculated based on the idea of benefit allocation, among which the benefits of aquaculture in the primary industry are calculated by use of the increasing income method. Finally, taking East Zhejiang water diversion project as an example, the economic benefits brought by East Zhejiang water diversion project in 2017 to the residents’ living and producing and three main industries are analyzed and calculated. The results show that the proposed quantitative method can be applied to the calculation of water supply benefits in practical inter-basin diversion projects better, and its results are more reasonable and practical than the previous single calculation method.

    Keywords: inter-basin water transfer; water resource allocation; water supply benefit; East Zhejiang water diversion

    MeasurementandtrendoftransformationandupgradationofcoastalportsbasedonDEA-Malmquistproductivityindex/MA Sai, FENG Xuejun, JIANG Liupeng, WANG Kaiwen(College of Harbour, Coastal and Offshore Engineering, Hohai University, Nanjing 210098, China)

    Abstract: From the perspective of total factor production efficiency of ports, the traditional data envelopment analysis (DEA) method is improved by using the Malmquist total factor productivity index, which overcomes the shortcomings of the traditional DEA method that cannot deal with different periods. The DEA Malmquist model with variable returns is established so as to investigate the upgradation degree and the development trend of transformation of ports. It is used to analyze the coastal ports in Shandong Province. The results show that the overall efficiency of coastal ports in Shandong Province has an increasing trend from 2014 to 2018. The development situations of various ports are not balanced. Although the Malmquist productivity index of the coastal ports in Shandong Province is restricted by the scale efficiency, it still has an increasing trend. Some suggestions are put forward for the transformation and upgradation of coastal ports in Shandong Province.

    Keywords: coastal port; transformation and upgradation; DEA; Malmquist productivity index

    Methodandexamplefordepartedcadres’auditofwaterresourceassetsbasedonaccountingaccounts/ZHOU Shenbei, ZHOU Lingling, WANG Xiaojing(Business School, Hohai University, Nanjing 211100, China)

    Abstract: From the perspective of results-process effectiveness, an audit method for water resource assets of departed cadres is proposed based on the accounting accounts. The input-output table is used to test the entrusted responsibility of water resource assets in Jiangsu Province from 2007 to 2012. In the process of trial calculation, the full permutation comprehensive evaluation method (FPCEM) is used to audit the water resource stock assets, and the comprehensive development index of water resources (CDIWR) is calculated to reflect the change state of the stock assets. The comprehensive environmental efficiency model (CEEM) is used to reflect the water-use structure (WUS) and efficiency (WUE) to audit the flow situation of water resource assets. The results show that during the audit period of Jiangsu Province from 2007 to 2012, the state of water resource stock assets exhibits the trend of “increase first then stable” after excluding the natural fluctuation factors, while the negative factor is found to be insufficient investment in the waste sewage disposal. The WUEs of manufacturing industries have improved slightly, while those of service industries have declined, resulting in the deterioration of the state of water resource flow assets. As the audit method is based on the standard accounts, the audit results can be reviewed, publicized and used for reference. It is of theoretical and practical significance to the implementation of departed audit system of the water resource assets in China.

    Keywords: accounting account; departed audit of resource asset; audit of inventory asset; audit of flow asset

    Full-costanalysisofseawaterdesalinationincoastalcities:TakingWeihaiPowerPlantofHuanengPowerInternationalInc.asanexample/ZHANG Lingling1, HE Mengting1,WANG Zongzhi2, LIU Kelin2, WU Ailing2(1.School of Public Administration, Hohai University, Nanjing 211100, China; 2.State Key Laboratory of Hydrology-Water Resources and Hydraulic Engineering, Nanjing Hydraulic Research Institute, Nanjing 210029, China)

    Abstract: With the rapid development of coastal cities, the conventional surface water and groundwater can no longer meet the social and economic development. Taking Weihai Power Plant of Huaneng Power International Inc. as an example, based on the full-cost theory, a full-cost analysis model for seawater desalination is established, and the resource cost, project cost and externality cost are calculated. The resource cost is considered from the value of utility and scarcity. The project cost includes the construction cost and initial investment cost. The effect of seawater desalination on the ecology is measured using the pollutant equivalent method. The full cost of desalinated water of seawater in Weihai Power Plant is 7.166 yuan/m3, of which the resource cost is 0.123 yuan/m3, the project cost is 6.597 yuan/m3and the externality cost is 0.446 yuan/m3. Compared with the prices of the current tap water and externally supplied water, there is no obvious price advantage for desalinated water. However, due to its stable water volume and safe water quality, it still has certain application potential in the urban water supply system in the future. Finally, in order to improve the competitiveness of desalinated water in the water supply system of coastal water-deficient cities, the relevant policy suggestions are put forward.

    Keywords: seawater desalination; coastal water-scarce city; water price; full cost; policy suggestion

    Domesticwaterpriceandaffordabilityofworldwideurbaninhabitants/GAO Huizhong1, WANG Xiaosong1, SUN Jing2, RUAN Hongxun3, MU Xiangpeng1, LI Xiang1,XU Fengran1(1.China Institute of Water Resources and Hydropower Research, Beijing 100038, China; 2.Beijing Institute of Water, Beijing 100044, China; 3.Guanghua School of Management, Peking University, Beijing 100871, China)

    Abstract: As the key economic lever, the water price plays an important role in promoting water saving. By analyzing the domestic water price and affordability of the worldwide typical urban inhabitants, the following conclusions are drawn: The full-cost water pricing method is widely adopted considering resource cost, project cost and environmental cost. The water prices in developed countries are significantly higher than those in China’s cities. In China, the water prices in the eastern cities are higher than those in the central and western cities, and those in the northern cities are higher than those in the southern cities. The water pricing modes include flat water price and combination of fixed cost and variable cost. The cities in China and Singapore as well as Tokyo City adopt the stepped water price. Although there are large differences in worldwide water prices, the ratio (R) of per capita monthly water bill to disposable income is close. The value ofRin each city is relatively low, and it is not incentive for water saving. The water price should be adjusted reasonably to support the construction of water-saving society.

    Keywords: domestic water price of inhabitant; affordability; water saving; comparative analysis

    Mediationstrategyofthirdpartyforupstreamanddownstreamwaterpollutionconflictbasedoninverseproblemofgraphmodelforconflictresolution/XU Haiyan, WU Zixin, WU Zhenggao(College of Economics and Management, Nanjing University of Aeronautics and Astronautics, Nanjing 211106, China)

    Abstract: For the upstream and downstream water pollution conflict, a third-party mediation model is established based on the inverse problem of graph model for conflict resolution. The model is used to obtain an equilibrium that minimizes the preference adjustments on the premise of fully considering the bottom line of preferences of both parties of the conflict. Based on the inverse problem theory, a 0-1 multi-objective programming third-party mediation model is proposed, and the model solution is designed. Finally, the model is applied to the water pollution conflict in the upstream and downstream areas, which further verifies the effectiveness of the model in solving mediation schemes and adjusting preferences. The third party can resolve the conflicts by using the model. The optimal state can be achieved that can make the upstream and downstream areas make the minimum preference concession so as to provide reference for the mediation of conflicts for water resources.

    Keywords: graph model for conflict resolution; inverse problem; water pollution conflict; third-party mediation; 0-1 programming

    EffectsandpotentialsofemissionmitigationofurbanindustrialpollutioninYangtzeRiverDeltaregion/JIANG Xiangcheng, SUN Xue(Business School, Hohai University, Nanjing 211100, China)

    Abstract: Rapid development of economy simultaneously causes industrial pollution. Based on the urban panel data in Yangtze River Delta region from 2010 to 2017, the comprehensive index of industrial pollution is established to evaluate the degree of urban industrial pollution by means of the entropy method, and then the LMDI multiplicative model is used to decompose the driving effects of the comprehensive index of industrial pollution into effect of economic scale, effect of economic structure, and strength and efficiency effects of investment in pollution treatment. Finally, the potentials of emission mitigation of industrial pollution in various cities are calculated. The results show that there is spatial distribution differences in the comprehensive index of industrial pollution in various cities in Yangtze River Delta region, further the differences gradually increase during the period from 2010 to 2017. The economic growth and the optimization of economic structure are respectively the primary and secondary factors for the increase of the comprehensive index of industrial pollution. The efficiency and strength effects of investment in pollution treatment are the primary and secondary factors for the restriction of the comprehensive index of industrial pollution.

    Keywords: comprehensive index of industrial pollution; driving effect; potential of emission mitigation; LMDI

    FairnessofallocationofwaterresourcesinJiangsuProvince/WU Zhaodan1,2,3, LIANG Shawan1, LIANG Xiyao4(1.Business School, Hohai University, Nanjing 211100, China; 2.Jiangsu Provincial Collaborative Innovation Center of World Water Valley and Water Ecological Civilization, Nanjing 211100, China; 3.Center of Africa Studies with One Belt One Road, Hohai University, Changzhou 213022, China; 4.College of Innovative Business and Accountancy, Dhurakij Pundit University, Bangkok 10210, Thailand)

    Abstract: Owing to its status of water shortage, endowment of water resources and spatial differences of water use in recent years, the fair allocation of water resources in Jiangsu Province of China is of great significance for playing a supporting role of water in economy and society and promoting the balanced development among various regions. From the perspective of society and economy, the fairness of allocation of water resources in Jiangsu Province is analyzed by means of the method of Gini coefficient and Theil index. The results show that from 2013 to 2017, the allocation of water resources in Jiangsu Province is relatively fair from the perspective of society, and the population and water resources are basically coordinated. However, from the perspective of economy, the allocation of water resources in Jiangsu Province is not fair to some extent. The water consumption and GDP have a relatively lower matching degree, and this unfairness is mainly caused by the differences of water use among three regions. Finally, some countermeasures and suggestions are put forward to improve the fairness of allocation of water resources in Jiangsu Province, including strengthening the unified management of water resources, giving priority to meet people’s domestic water use, reasonably arranging water use for economic production, and improving control target of water use.

    Keywords: water resource allocation; fairness; water resource management; Gini coefficient; Theil index

    SpatialandtemporalpatternsofecologicalfootprintofwaterresourcesinJiangxiProvince/GU Wenlin, LIU Feng, JING Peiran(Business School, Hohai University, Nanjing 211100, China)

    Abstract: Based on the models for ecological footprint and ecological carrying capacity of water resources, an evaluation index system including ecological surplus (deficit) per capita of water resources, ecological pressure index of water resources and ecological footprint of water resources of ten thousand yuan GDP is established to analyze the spatial and temporal patterns of ecological footprint of water resources in Jiangxi Province from 2010 to 2018. The results show that in terms of time series, the ecological footprint of water resources in Jiangxi Province and prefecture-level cities generally has an increasing trend, and the ecological carrying capacity of water resources fluctuates greatly. In terms of spatial distribution, the ecological footprint and carrying capacity of water resources in Ganzhou City and Yichun City are in the forefront of Jiangxi Province, and there are great differences among other cities. Nanchang City has the ecological deficit per capita of water resources in some years, and its ecological pressure index of water resources is relatively large. However, the ecological footprint of water resources of ten thousand yuan GDP is low, and the utilization efficiency of water resources is the highest in Jiangxi Province.

    Keywords: water resource; ecological footprint; ecological carrying capacity; spatial and temporal pattern; Jiangxi Province

    Abstract: The PMC index model is used to quantitatively evaluate the reservoir resettlement policy in China from 2001 to 2018. By constructing the evaluation index system of reservoir resettlement policy, calculating PMC index and drawing images, the advantages and disadvantages of various policies are analyzed. The results are as follows: The combination of policies in various fields. the government’s multi-party participation and various support measures under the leadership of the government have become the main policy formulation direction for China to alleviate and solve the reservoir resettlement problem so as to achieve the overall stability of the reservoir areas and society. There is still much room for improvement and optimization in reservoir resettlement policies, and the corresponding optimization suggestions should be put forward based on the specific policy scores. Finally, according to the overall evaluation situation of reservoir resettlement policy, some reference suggestions are provided for the formulation, implementation and optimization of reservoir resettlement policies in China from three aspects: the nature of policies, the participants and the focus stage.
