ABSTRACT This research is an in-depth study of Korean GTCs (General Trading Companies) and Japanese Sogo Shoshas (the Japanese version of General Trading Companies), which are unique big business conglomerates but not well-known in Western countries. It investigates and compares several of their features, such as their history, characteristics, functions, organisational structure, corporate culture, human resource management, their impact on national economic development, strategic management and decision-making process. First, it examines a wide range of literature to show the functions of Korean GTCs and Japanese Sogo Shoshas as transaction intermediaries, information gatherers, project organisers, international marketers, financial providers, etc. With these varied functions, they have played significant roles not only from the macro aspect, but also the micro aspect. To rationalise their theoretical existence, they are approached from four perspectives: transaction cost economics, informational economics of scale, international marketing, and as financial intermediaries. Second, many elements were examined to scan the general management system within the two groups. Compared to Western countries, both Korea and Japan traditionally have a collectivist culture with low individualism. However, there have been transformations in the culture in terms of employee values, attitude, behaviour and management style. These cultural changes have been reflected in human resource management practice. Traditional human resource management practices lost their effectiveness, as they proved to be unfit for the changing business environment. i Traditional features such as lifetime employment, seniority-based pay and recruitment patterns have been changing since the slower growth of these economies in the 1990s. Corporate governance and ownership structure were also examined. In Korea’s case, control power has been centralised to group owners and their excessive power over ownership has caused problems, especially in the decision-making process. But ownership and management in Japan have traditionally been separated. Third, as a main purpose of this research, a field survey was carried out to examine the strategic management of the two groups by analysing the relationships between the business environment, competitive strategy, organisational structure and performance. As in the previous literature, this research also found that the variables are not independent, but interdependent with the other variables. Environment influences a firm’s competitive strategy and strategy affects its organisational structure. Then, performance is influenced by strategy and structure. For instance, a firm’s employment of differentiation strategy is positively associated with environmental uncertainty and complexity. A differentiation strategy is positively correlated with organisational decentralisation. Consistent with the previous literature, a cost leadership strategy is statistically positive with organisational formalisation. A hybrid strategy and new market development are positively correlated, since the main purpose of this strategy is to offer high-quality products or services at lower prices than competitors do. The research also found that organisational decentralisation motivates and encourages employees’ satisfaction and retention. Fourth, the decision-making process within the two groups was compared. Top executives in Korean GTCs still play important roles in the decision-making process, ii whilst, team leaders and middle managers are positioned as main bodies in Japanese Sogo Shoshas. As primary factors influencing decision-making, ownership and corporate culture are the most important factors in Korean GTCs, whilst corporate culture is a primary component in Japan. Korean decision-makers tend to be individualistic, but Japanese decision-makers practice collectivism. There have been significant changes in decision-making both in Korean GTCs and Japan Sogo Shoshas since the 1990s. Fifth, in totality, some differences in the general management system were found between the two groups. These may be caused by cultural differences, history, organisational size and/or the degree of business scope and diversification. iii ACKNOWLEDGEMENTS I wish to thank the many people who have encouraged, or assisted in, the preparation of my PhD. thesis. This work would not have been possible if it had not been for the help and support of many people. In this short preface I am not able to acknowledge everyone by name. First and foremost, I would like to express my deep and sincere thanks to Professor Jim R. Slater, who has supervised my study for the past three years. His expertise in Strategic Management, as well as his assistance in many other phases, was especially beneficial in completing this dissertation. No amount of words can express my gratitude to him. My special thanks and gratitude are extended to Professor David Bailey. I am greatly indebted to him for his endless efforts and warm assistance in clarifying and refining this dissertation. The useful comments he has given me on Japan-related research were particularly helpful. For my field survey, I am indebted to many people. I especially thank the contact people in Korean GTCs and Japanese Sogo Shoshas, in particular, Mr. Ki Sung, Cho, a manager of Lotte Group, and Mr. Keisuke Sasaki, a senior manager of Tomen Corporation. I also thank all the respondents who participated in my field survey. Most of them gave their total support and encouraged me. I would also like to acknowledge my gratitude to my family. Without their devotion and sacrifice, I could never have finished all my academic journey in the U.K. I especially thank my mother, Gae Soon, Lee, and my brothers and sister, Hong Woo, Young Woo, and Gae Sun, who have given me their emotional and financial support over the years. Finally, I should not forget my only daughter, Eun Chae, who has given me emotional encouragement during my study. With all my heart, I dedicate this dissertation to my family. iv LIST OF TABLES Table 2.1. Definitions of the GTCs/Sogo Shoshas 18 Table 2.2. Market Governance Structure 27 Table 3.1.
