Identification of Heterogeneity of Social and Economic Environment of Land Uses in China

The robust principal component analysis （RPCA） is a technique of multivariate statistics to assess the social and economic environment quality. This paper aims to explore a RPCA algorithm to analyze the spatial heterogeneity of social and economic environment of land uses （SEELU）. RPCA supplies one of the most efficient methods to derive the most important components or factors affecting the regional difference of the social and economic environment. According to the spatial distributions of the levels of SEELU,the total land resources of China were divided into eight zones numbered by Ⅰ to Ⅷ which spatially referred to the eight levels of SEELU.

Ivory Coast Intra Regional Trade： The Role of Infrastructure and Economic Environment

Intra-regional trade dynamic can foster economic integration with a contribution of the lead economy. In that way, infrastructure and economic environment play an important role in expanding trade by reducing trade costs. This paper examines the role of infrastructure and the economic environment on Ivory Coast intra-regional trade. The study performs a transformed and advanced gravity model, using panel data over the period 1996 to 2013, modelling exports of Ivory Coast. The analysis shows experts towards the other member states of West African Economic and Monetary Union （WAEMU） depend significantly on the availability of transport and communication infrastructures developed as well as variables such as Gross Domestic Product growth, economic similarity within countries, Foreign Direct Investment （FDI） net inflows in Ivory Coast. Estimations point out that indeed, the level of economic growth in the other member countries, Foreign Direct Investment （FDI） net inflows in Ivory Coast, the number of mobile phone subscribers per 100 inhabitants in Ivory Coast and the proportion of paved roads, have a positive impact on Ivory Coast intra-regional trade.

Fractional Order Environmental and Economic Model Investigations Using Artificial Neural Network

The motive of these investigations is to provide the importance and significance of the fractional order(FO)derivatives in the nonlinear environmental and economic(NEE)model,i.e.,FO-NEE model.The dynamics of the NEE model achieves more precise by using the form of the FO derivative.The investigations through the non-integer and nonlinear mathematical form to define the FO-NEE model are also provided in this study.The composition of the FO-NEEmodel is classified into three classes,execution cost of control,system competence of industrial elements and a new diagnostics technical exclusion cost.The mathematical FO-NEE system is numerically studied by using the artificial neural networks(ANNs)along with the Levenberg-Marquardt backpropagation method(ANNs-LMBM).Three different cases using the FO derivative have been examined to present the numerical performances of the FO-NEE model.The data is selected to solve the mathematical FO-NEE system is executed as 70%for training and 15%for both testing and certification.The exactness of the proposed ANNs-LMBM is observed through the comparison of the obtained and the Adams-Bashforth-Moulton database results.To ratify the aptitude,validity,constancy,exactness,and competence of the ANNs-LMBM,the numerical replications using the state transitions,regression,correlation,error histograms and mean square error are also described.

Environmental and economic assessment of structural repair technologies for spent lithium-ion battery cathode materials

The existing recycling and regeneration technologies have problems,such as poor regeneration effect and low added value of products for lithium(Li)-ion battery cathode materials with a low state of health.In this work,a targeted Li replenishment repair technology is proposed to improve the discharge-specific capacity and cycling stability of the repaired LiCoO_(2) cathode materials.Compared with the spent cathode material with>50%Li deficiency,the Li/Co molar ratio of the regenerated LiCoO_(2) cathode is>0.9,which completely removes the Co_(3)O_(4) impurity phase formed by the decomposition of LixCoO_(2) in the failed cathode material after repair.The repaired LiCoO_(2) cathode mater-ials exhibit better cycling stability,lower electrochemical impedance,and faster Li^(+)diffusion than the commercial materials at both 1 and 10 C.Meanwhile,Li_(1.05)CoO_(2) cathodes have higher Li replenishment efficiency and cycling stability.The energy consumption and greenhouse gas emissions of LiCoO_(2) cathodes produced by this repair method are significantly reduced compared to those using pyrometallurgical and hydro-metallurgical recycling processes.

Solving Multi-Area Environmental/Economic Dispatch by Pareto-Based Chemical-Reaction Optimization Algorithm

In this study, we present a Pareto-based chemicalreaction optimization(PCRO) algorithm for solving the multiarea environmental/economic dispatch optimization problems.Two objectives are minimized simultaneously, i.e., total fuel cost and emission. In the proposed algorithm, each solution is represented by a chemical molecule. A novel encoding mechanism for solving the multi-area environmental/economic dispatch optimization problems is designed to dynamically enhance the performance of the proposed algorithm. Then, an ensemble of effective neighborhood approaches is developed, and a selfadaptive neighborhood structure selection mechanism is also embedded in PCRO to increase the search ability while maintaining population diversity. In addition, a grid-based crowding distance strategy is introduced, which can obviously enable the algorithm to easily converge near the Pareto front. Furthermore,a kinetic-energy-based search procedure is developed to enhance the global search ability. Finally, the proposed algorithm is tested on sets of the instances that are generated based on realistic production. Through the analysis of experimental results, the highly effective performance of the proposed PCRO algorithm is favorably compared with several algorithms, with regards to both solution quality and diversity.

Environmental economic geography:Recent advances and innovative development

Modern environmental problems are the result of human-environment interaction in the process of industrial-ization.The relationship between economic development and environmental quality is an important aspect of understanding human-environment interaction and has been widely concerned by multidisciplinary researchers.Economic geography(EG)is a discipline that mainly focuses on the location and connections of economic activi-ties.EG has developed to environmental economic geography(EEG)by incorporating environmental factors into its research framework,considering the operational mechanism of the co-evolution of economy and environment,and the dynamic process of green transition of techno-economic paradigms.Studying the resource and environ-mental effects of R&D,production,trade,and other aspects of the economic cycle is beneficial to realizing the“greening”economy.This paper traces the background and theoretical development path of EEG and elaborates on the interaction between EEG and other research paradigms on environmental problems.In recent years,the focuses of EEG are as follows:(1)the“location-environment”relationship of production from the perspective of local actors;(2)the“GVC/GPN-environment”relationship of multinational enterprises and space of flows from the perspective of the global network;(3)the“trade/circulation-environment”relationship from the perspective of national linkages;and(4)the co-evolution of the economic system and environment from the perspective of synergistic evolution,with a focus on innovation and institutional forces.The future development trend of EEG is combined with the endogenous growth theory and the sustainable development theory,mainly from the aspects of endogenous,system integration and multi-scale,to explain the differences in environmental issues of differ-ent regional economic activities,and to promote the development of EEG theory and interdisciplinary research,strengthening the construction of global and regional sustainable development system.

The application of environmental economics in marine functional zoning and coastal city conceptual planning

There are a lot of functions of marine resources. The various and competing conflicts between different users and different sectors in the use of marine resources will cause the disorderly development of marine resources, and even destroy the marine ecosystem. Marine functional zoning is an effective tool to solve the conflicts. However, there are some shortcomings in the current understanding on marine functional zoning and its practice. In this paper, a case study on the resource-oriented marine functional zoning of Xiangshan Port is introduced. By the principles of resource-oriented and public participation, Xiangshan Port is divided into seven zones, and the main function of the whole port and seven zones are determined by the environmental economics analysis. A case study of Xiamen is also introduced for how to integrate marine functional zoning into a coastal city conceptual planning. Under the conservation principle, resources-oriented principle and so on, the advantages and disadvantages of natural ecosystem, social ecosystem and economic ecosystem are holistically analyzed, the urban orientation of Xiamen is determined as a regional international tourism city, and the whole city is divided into five function zones according to its leading industry -tourism. Resource-oriented marine functional zoning has a long-term guidance for sustainable use of marine resources and development strategy of a coastal city. And environmental economics analysis is an effective tool for resource-orientation.

Reference Point Based TR-PSO for Multi-Objective Environmental/Economic Dispatch

A reference point based multi-objective optimization using a combination between trust region (TR) algorithm and particle swarm optimization (PSO) to solve the multi-objective environmental/economic dispatch (EED) problem is presented in this paper. The EED problem is handled by Reference Point Interactive Approach. One of the main advantages of the proposed approach is integrating the merits of both TR and PSO, where TR has provided the initial set (close to the Pareto set as possible and the reference point of the decision maker) followed by PSO to improve the quality of the solutions and get all the points on the Pareto frontier. The performance of the proposed algorithm is tested on standard IEEE 30-bus 6-genrator test system and is compared with conventional methods. The results demonstrate the capabilities of the proposed approach to generate true and well-distributed Pareto-optimal non-dominated solutions in one single run. The comparison with the classical methods demonstrates the superiority of the proposed approach and confirms its potential to solve the multi-objective EED problem.

Grasping Changes in Environment from the Economic Angle

It is of great significance to have a clear understanding of the international environment that China faces. But this is an uneasy job. Since September 11, the world situation has become so complicated that it is hard to grasp its essence even with painstaking efforts. To judge such an already complicated international environment from China’s perspective adds more difficulties, for different people usually have different views due to the different angles from which they see the situation and different methods they adopt. This, understandably, leads to hot debates within the Chinese academic circles. To provide a stage for exchange of views, at the invitation of the CIR Expert Forum, some well-known scholars and experts on international relations from Beijing gathered to hold a symposium on November 5, 2002, with the theme of "How to assess the international environment that China faces". The speeches at the symposium are published in two installments. Following are the second half.
