Electronic commerce, or e-commerce as I will refer to it, is a hot topic. Electronic commerce is becoming increasingly popular as a way of doing business and its role constantly increases. E-commerce is changing the way companies do business and it is not only about trading with the usage of the new technology. It is a new way of working for the whole organisation. Companies are interested in usage of electronic commerce because this way of conducting business brings them measurable benefits. The benefits come not only through direct cost savings but also through the improved efficiency of companies rethinking how they operate. In general the benefits can be gained by increasing or sustaining sales on a certain level and by reducing time and costs related to buying and selling goods. The thesis examines the use of e-commerce in the chemical sector. That industry was selected because it is one of the major sectors that have been already using ecommerce in its operations and have big potential for growth. The main goal of this dissertation is to examine the hypothesis: "Will electronic commerce take over the majority of the trade in the chemical sector?" In order to be able to give a response to that issue the dissertation starts with a general presentation of e-commerce and its diversification into different forms. I examined three methods of electronic commerce: Electronic Data Interchange, electronic marketplaces, and Internet e-commerce (Chapter 1). Electronic marketplaces are currently the fastest developing form of electronic commerce. Their diversity gives many options to a wide range of business organisations. Thus, this type of e-commerce is presented in detail by giving descriptions of the forms in which it occurs (Chapter 2). In order to analyse the hypothesis that is related to the future situation, it is necessary to look at the current situation of e-commerce in the chemical sector. The use of electronic commerce is discussed in the context of chemical companies that already use some forms of electronic commerce and virtual marketplaces that operates in the chemical goods market. I present the situation in this field in Poland as a country representative of a new, fast growing Central European market economy (Chapter 3). Finally, the future situation is examined. The future of electronic commerce is analysed from the general business perspective, executives' expectations and the situation in the chemical industry. In conclusion, this dissertation successfully reaches a proof for my fundamental hypothesis (Chapter 4).
