This paper proposes see how the new technologies related to the concept of smart grids can influence on the current technological model of power transmission infrastructure in NAFTA. The comparative analysis of energy integration and smart grid technologies applied in bloc countries show that: for over four decades began on robust initiatives for cross-border electricity interconnection in North America,...
This paper analyzes several circulation models of the agricultural super docking, and points out some produce distribution problems under these models. The conception of loss function is introduced to establish the mathematical model, which is based on the produce delivery. The GA (Genetic Algorithm) is also used to figure out the optimal path.
SCGE models are ideal tool for modelling socioeconomic effects in a spatial manner. The current research is investigating this modeling methodology from the view of transportation and investigating the reciprocal cooperation possibilities with ITS systems. In this combined approach the main aims are to identify the different infrastructure and ITS development possibilities and their effects to set...
We present an energy market equilibrium model that captures climate aspects, infrastructure constraints, fuel substitution, and market power ala Cournot in a single framework. The model represents the supply and transportation infrastructure, fuel transformation, power generation, and several demand sectors of fossil fuels, renewables and nuclear energy. We calibrate the model to market data from...
In order to evaluate the overall economic impact of a natural disaster considering the recovery process, attention needs to be paid to the problem of double counting of economic losses. For this purpose, it is necessary to answer the following research questions: (1) how does a natural disaster impact the economy at each phase of the disaster and recovery, and (2) how do you consistently evaluate...
Since the 21st century, China's wheat processing industry has been growing drastically, spatial structural has been changing considerably. The characteristics of the location, movement of wheat processing sector are summaried in this paper. Empirical models are developed and estimated to identify economic determinants of wheat processing establishment growth between 2000 and 2009. Raw materials production,...
According to economic ideas of Gary s. Becker, this paper builds the decision-making model of rural highway scales from the perspective of farmers under funds constraint, and gets the equilibrium condition of rural highways scales. Then with the figure analysis, the paper discusses impact mechanism of the several factors such as the financial structure of rural highway, rural urbanization, rural economic...
Accessibility is taken for the comprehensive and effective method for traffic network evaluation, and gradually is used in diversified domain, such as urban planning, traffic planning, spatial structure and regional economy development. GIS as a kind of new technology, it provides a more simple, accurate and effective tool for the computing of accessibility. Usually, the study of accessibility only...
The paper analyzes the concept, elements and data structure of the multi-mode transportation network, proposes a polycentric hierarchy description model of the integrated transportation network, and discusses the construction method of multi-mode transportation network using GIS technology. The design of system function modules provides a visual edition platform to realize the construction of integrated...
This paper puts forward a two-stage correlative DEA model to measure airport production efficiency. The complicated production process of decision-making units is decomposed into two sub-processes. The correlative DEA model is used to evaluate the airport production efficiency by considering the co-relationship of sub-processes within the whole production process; an empirical study on 8 airports...
This paper constructs a general spatial economic model integrating land rent and transport cost according to the actualities of industrial aggregation and relocation of China. Then it uses numerical simulation to gauge the significance of the model. We found that the level of rents and wages were decisive factors in the model while the effect of transportation was in two-ways. Applying this proposition...
The paper studied the heterogeneity of the effect of producer services on China's industrial economic growth. Our empirical study was made on industrial panel data sets. The results of our empirical study were robust to prove that producer services in the industrial sector have a positive impact on economic growth, but there were differences between the three different factor- intensified industries...
The most significant energy consuming infrastructures and the greatest contributors to greenhouse gases in the US today are electric and freight/passenger transportation systems. Technological alternatives for producing, transporting, and converting energy for electric and transportation systems are numerous. Selecting from among them requires long-term assessment since these capital-intensive infrastructures...
With the method of principal components analysis, the paper establishes highway transportation development exponent and economy development exponent successfully, which can represent the historic status, current status and future trends of highway transportation and economy development respectively. This shows it is feasible to express the development of highway transportation and economy with the...
Increasing importance of sustainable development has lead eco-efficiency to find a specific position in literature. Eco-efficiency means producing goods and delivering services by using lower energy and raw material which together result in lower amount of wastes, pollution and cost. Eco-efficiency considers two aspects: economical and environmental. The purpose of this article is to design reverse...
This paper presents an approach to simulating alternative supply chain configurations and analysing their respective sensitivities to external factors. First of all, the approach used for modelling the supply chain environment, characterized by uncertain factors, is presented. The factors that influence supply chain performance include elements such as customer demand, currency exchange rate, transportation...
Electronic commerce and transportation services play an important role in FDI (foreign direct investment) distribution in China. One region with higher developed electronic commerce and transportation services receives more FDI. FDI absorbed by one region of China is affected by other regions. This effect is also closely related with electronic commerce. This essay, based on the data of China from...
This article will introduce the elements of inter-regional flows, as a place to study the formation of specialized industrial clusters. We are going to find how the technology-induced elements in regional differences promote the professionalization of the industrial cluster development and growth mechanism. We also establish a "dual economy" characterized by general equilibrium model, at...
In order to satisfy the Chinese enterprisespsila demand for the import of hi-tech equipment and reduction of costs during the import process, we need to construct an electronic alliance import platform for hi-tech equipment. This article attempts to apply the advantages of a large-scale electronic purchase platform for hi-tech equipment through the implementation of an "online reverse auction"...
The problem how the shipping proprietors stimulate their employees to reduce costs under asymmetric information is discussed on the basis of principal-agent theory. The shipping proprietors determine a contractual base according to their demand and how much the employees confirmed, and compare it with the actual cost so as to offer reward or penalty to the employees. Based on such contractual procedure,...
