Enterprise Information Engineering Model and Its Integrated Support Environment

By analyzing the process of enterprise information engineering construction and intra relationship among information system requirement, business process modeling, application system constructing and project management, one of 4 meta model composed of requirement engineering, process engineering, application system engineering and support engineering is proposed for enterprise information engineering. The developments and applications of the business processes and its application systems are integrated into the same development space and application space. Basing on this, a prototype system composed of requirement modeling environment, business process modeling environment, application system modeling environment, and support engineering environment has been designed and built, which is used for supporting enterprise information engineering constructing. It is valued for the enterprise information engineering construction in our country.

Impacts of IT Advances and E‐commerce on Transportation in Producer Services

ABSTRACT Producer services have been among the most rapidly growing industries, as measured by employment, in the United States and in Europe in recent decades. The production and delivery of these specialized forms of service industry work require the use of transportation and communications systems in a variety of ways, including the physical movement of people working in these industries, as well as the movement of the information related to the production and distribution of their work. Some of this work is performed in localized markets, requiring travel between clients and suppliers in local transportation modes, such as auto, bus, or other types of transportation. Other work is done by specialists who travel interregionally and globally to do their work, primarily traveling to their clients. There is little knowledge of how these production relationships have changed with the advent of the Internet and the widespread use of e‐mail in the business production process. Within the framework of this STELLA initiative, this paper outlines research needs in this area, and frames an approach that would produce badly needed knowledge about impacts on the producer services of the Internet and related e‐commerce initiatives on physical transportation systems at a local to interregional scale.     

Investigation of e‐commerce in China in a geographical perspective

In recent years, e‐commerce has become a phenomenal symbol for the ongoing socio‐economic transformation in China. Driven by the growth of the Internet and cyberspace, e‐commerce changes both the traditional patterns of economic transactions and the social relations embedded in social activities. E‐commerce is a new catalyst for economic growth in China as it reduces restrictions to market access and the costs of transaction. This research examines the geography of e‐commerce in China within a theoretical framework grounded by social theory and neoclassical economics. After presenting a background of the development of e‐commerce in China, the spatiality of e‐commerce and its correlation to socio‐economic variables are examined with both quantitative and geovisualization techniques. Results of this research address that the growth of e‐commerce in China presents a nationwide inequality constrained by local economic, politic, and infrastructure conditions. The growth of e‐commerce in China presents a hybrid feature in terms of spatiality, which relies on structures in both cyberspace and physical space. Policy implications and suggestions for future research were suggested based on these empirical results. A discussion of limitations associated with this research and a concluding note close the research.     

Improving Local Manufacturing Employment Forecasts Using Cointegration Analysis

Procedures for tracking and forecasting economic conditions in regional economies have evolved significantly over the last 30 years. Much of this evolution has followed developments in macroeconomics, where techniques for tracking/forecasting key economic variables have tended to originate. This technique adoption and adaptation process continues today, as developments in the technique adoption and adaptation process continues today, as developments in the modeling of cointegrated macroeconomic time series have begun to appear in the regional modeling and forecasting literature. This paper presents an effort at modeling a segment of a regional economy using the cointegration testing procedures suggested by Johansen and Jusilius (1990) to develop a forecasting model for manufacturing employment in Milwaukee, WI. The paper demonstrates how Vector Error Correction (VEC) modeling can lead to gains in the accuracy of local manufacturing employment forecasts relative to more traditional VAR models in either levels or first-differenced form. In the process, it demonstrates procedures for developing a relatively simple VEC model that reveals something about the structure of the local manufacturing sector, including possible linkages to the national economy. This information can assist local policy makers in anticipating and adapting to business cycle-related fluctuations in this critical sector of the local economy.

Urban–Rural Differences in Internet Usage,e‐Commerce,and e‐Banking: Evidence from Italy

ABSTRACT By reducing the cost of performing isolated economic activities in remote areas, information technology might serve as a substitute for urban agglomeration. The paper assesses this hypothesis using data on Italian households' usage of the Internet, e‐commerce, and e‐banking. The results do not support the argument that the Internet reduces the role of distance. Internet usage is much more frequent among urban consumers than among their non‐urban counterparts. The use of e‐commerce is basically unaffected by the size of the city where the household lives. Geographically remote consumers are discouraged from purchasing goods by the fact that they cannot inspect them beforehand. Leisure activities and cultural items (i.e., books, CDs, and tickets for museums and theaters) are the only goods and services for which e‐commerce is used more in isolated areas. Finally, e‐banking bears no relationship to city size. In choosing a bank, non‐urban customers give more importance to personal acquaintance than do urban clients, partly because bank account holders in remote areas are more likely to have taken out a loan from their bank.     

The Centralize-Distributed Structure Model of Electronic-Business that Based on the Concept of Field-Bus Control System

Electronic business is a model of automation business activities, so the concept of field bus control system that is the latest control technology in automation control domain could be transplanted into electronic business structure to optimize the performance of the electronic business. The author studied the model which had centralize distributed structure and built under the concept of FCS in the environment of electronic business. By analyzing the performance of shops online, authority center and logistics distribution center that have the centralize distributed structure, the conclusions could be drawn that the centralize distributed structure model of electronic business has the advantages of high reliability, rapid response, high expandability, easy to rebuild and high system efficiency that FCS has.

The formation of agricultural e‐commerce clusters: A case from China

Agricultural e‐commerce clusters are new phenomena that have emerged in rural China. In examining the case of Shuyang County in Jiangsu Province, this paper puts forward an integrated model revealing the formation mechanism of agricultural e‐commerce clusters. The paper shows that the formation of agricultural e‐commerce clusters involves four processes of technology introduction, technology diffusion, quality crisis, and industrial agglomeration based on elements such as industry bases, e‐commerce platforms, network facilities, logistics services, entrepreneurial talent, local government, and market demand. Rural social networks and imitation behaviors promote technology diffusion by reducing the cost of technology introduction, and industrial agglomeration is found in the economies showing a deepening of labor divisions and geographic agglomeration. Throughout the formation process, a quality crisis may occur due to a race to the bottom and the opportunistic behaviors of local farmers. This work suggests that regional e‐commerce development is a systematic project. Governments of developing countries should not only realize the positive impacts of e‐commerce for the development of the agricultural industry but also recognize the premise and logic of how e‐commerce can play a prominent role.
