Based on the three-terminal interval number and the project risk theory, this paper discusses the problem of risk weighting in uncertain market decision-making, and puts forward the method of combining the grey system theory and the three-terminal interval number to determine the weight of decision-making. The best-selling weight, the unsalable weight and the normal weight are calculated by expert...
Man-land relationship reflects the interdependence and interaction between man and nature. This paper gives an overview of the definition of human-land relationship and its characteristics, and analyzes the contradictions and problems in the process of exploitation and utilization of land. Combined with this basis and the guidance of the coordination theory of man-land relationship, this paper puts...
The article discusses the strategy for evaluating of the natural and industrial system performance at the mining and processing complex. The methods comprising a systematic approach position allowing one to unite technological, economic, social and technogenic aspects are developed. Evaluation of the natural and industrial systems (NIS) functioning effectiveness is conducted using the integral sustainable...
Timber Purchasing Managers' Index (PMI) has been perceived as the barometer of timber industry evolution. The weight scheme is at the core of constructing the index. In this study, an in-depth analysis on the weight scheme of Timber PMI is conducted. The empirical results reveal that the current weight does not affect the leading function of Timber PMI, but it is not the optimal weighting method....
The accelerated development of renewable energy sources (RES) technology and their enhanced integration into the low voltage (LV) distribution network require changes in the network operational procedures. New technologies like smart inverters developed within EU FP7 project INCREASE have been developed in order to help the Distribution System Operators (DSO) in keeping the network parameters within...
The integration of informatization and industrialization (IOII) is a policy guidelines proposed by the Chinese Government to promote the production upgrade and the transformation of economic development mode, which is given increasingly attention by academic circles. In this paper, a brief introduction to IOII is presented. The research collections of IOII required to study the theory and application...
This research presented three kinds of evaluation methods that can be feasibly applied for the short energy and water sources areas, such as the evaluation methods of regional potential energy including the estimation of general potential energy, and the energy used in the industrial production process, and also the available renewable energy that may be developed. The Potential Energy Index that...
Urban infrastructure construction can promote the development of the national economy and society. The performance evaluation of urban infrastructure investment reflects the relationship between input and output, and it is an important index to measure the effect of operation. Therefore, it is necessary to study the evaluation index system and method of urban infrastructure investment performance...
By taking Beijing high technology industry cluster as the research object, this paper utilizes such analysis indexes as industrial concentration ratio, space Gini coefficient and industrial agglomeration rate to complete the evaluation on the development degree of Beijing high technology industry cluster and to make analysis on the empirical results based on the discussion on the status quo of industry...
This paper develops a Schumpeterian R&D growth model with endogenous directed technological change. The aim is to study the contributions of environmental policies to the production of ecological goods, when consumers are indifferent between ecological and dirty goods. By solving the transitional dynamics numerically and by removing the scale effects, it is shown that, through the price channel,...
The transition toward a significant penetration of renewable sources in electricity generation, although desirable under an environmental viewpoint, is likely to be very costly due to the scarce adaptability to Renewable Energy (RE) sources characterized by relevant intermittency. In fact, generation from RE sources implies a change in the scheduling of the rest of generating facilities, which may...
The 21st century is the age of knowledge and creative economy. As an emerging industry, the cultural and creative industry is developing vigorously, and becoming more and more important in regional economic development. Especially for China, which is now facing the most critical period of economic growth mode transformation, the development of cultural and creative industry would play an important...
The present situation of Highway transportation and its economic development are not matching in Chang-Ji-Tu area; therefore use the DEA model to evaluate the highway transportation efficiency of Chang-Ji-Tu area. From the aspects of the comprehensive effectiveness, scale benefit, input and output analysis, the conclusions are that highway transportation efficiency is too low, there are inadequate...
From the analysis of the behavior of farmers, proposing the comprehensive production capacity of understanding, and building a comprehensive production capability evaluation index system. In the central eight provinces in 2012 data as the sample, using correspondence analysis and factor analysis, discussing the different area production characteristics, overall household farmers' production capacity...
This paper has derived from empirical generation methodologies of indexes which are mainly focus on sustainability or environmental performance and provided critical mapping for these indexes originally. By categorizing indexes from several dimensions, we suggested an analyzing approach as innovator for new researchers to find new research questions and gaps. This approach is along determinants which...
This paper first analyzes the trade profile of Strategic Emerging Industries from the perspective of volume, trade forms and ownership. Processing trade form and foreign owned companies play important role behind the phenomenon of explosive growth for export of China's High-tech products. Based on input-occupancy-output models of the non-competitive type, this paper then further calculate the Strategic...
Virtual cultivated land refers to the quantity of cultivated land resources needed during the production of goods and service. This paper chose four kinds of main grain products i.e. rice, maize, wheat and soybean, and calculated their trade volume of virtual cultivated land in main grain production regions. Based on the calculation of cultivated land pressure index in main grain production regions,...
This paper uses the Method of Data Envelopment Analysis (DEA) to evaluate the efficiency of urban tourism, and chooses the BC2 model to make time series analysis on tourism efficiency of a city in 2000–2010. By analyzing the results of the evaluation we can try to determine the development level and the corresponding future development space of the tourism efficiency in the city which will provides...
This paper presents initial results of a three-year research project entitled ATLANTIDE, which is aimed at developing a comprehensive digital archive of reference models of Italian distribution networks, including forecasted load and generation development evolving towards future smart grid scenarios. Such reference network models and evolutionary scenarios should provide a useful benchmark for testing...
The data envelopment analysis method is adopted to evaluate operational efficiency of marine economy in order to discover and resolve their input redundancy and output insufficiency so as to improve their operational efficiency. In order to give some progressive proposals and improve the efficiency of the input and output index to measure marine resource and economy, in the part of the demonstration,...
