1.0    Introduction

This paper examines how globalization of e-commerce is impacting business in general. With the increase of internet-based technologies, it has been the reason for recent stimulus globalization. In this Information Age, Internet commerce is a powerful tool in the economic growth of developing countries. While there are indications of ecommerce patronage among large firms in developing countries, there seems to be little and negligible use of the Internet for commerce among small and medium sized firms. E-commerce ensures better business in the SMEs and sustainable development of economics for developing countries. However, this is based on strong political will and good governance with a responsible and supportive private sector within an effective policy framework. As we know the complete definition of E-commerce is the use of electronic communications and digital information processing technology in business transactions to create, transform, and redefine relationships for value creation between or among organizations, and between organizations and individuals. E-commerce allows companies to increase their sales in domestic and foreign operations and the flexibility afforded by the technology also provides less costly opportunities to locate operations strategically. E-commerce not only reduces communication costs, but also increases flexibility in locating activities. Research point indicates that internet technology has led to an increase in international trade (Freund and Weinhold, 2002, 2004). This is the evidence of how it suggests profits from foreign operations have also increased in recent years (Hilsenrath, 2005).

The controversial current social and economic trends are globalization and the widespread adoption of information and communication technologies (ICTs). Many argue that these two trends are closely associated, each driving the other forward, and both being driven by other common forces, such as trade liberalization, deregulation, migration, and the expansion of capitalism and democracy (c.f., Held et al., 1999). Pohjola (2002) argues that the twin forces of globalization and the ICT revolution are combining to create the so-called New Economy, marked by higher rates of economic and productivity growth. “Technology is both driven by and a driver of globalization, as both forces continually reinforce one another” cited by (Bradley et al., 1993).Specifically,the use of ICT for ecommerce in business has enhanced productivity, encouraged greater customer participation, and enabled mass customization, besides reducing costs.Prior to development in the Internet and Web-based technologies, the distinctions between traditional markets and the global electronic marketplace-such as business capital size, among others-are gradually being narrowed down. Strategic positioning is the ability of a company to determine emerging opportunities and utilize the necessary human capital skills (such as intellectual resources) to make the most of these …
