This book brings together papers written by representatives from UN agencies and academics who take a fresh look at the expanding role of transnational corporations and foreign direct investment in the world economy. These papers deal with such issues as the nature and extent of globalisation, the shifting relations between transnational corporations and national economies, and the opportunities and obstacles facing policy makers in the rapidly changing global economy.

This book represents the first attempt to conceptualize the social and cultural impact of transnational enterprises on host nations and to provide empirical and analytical material on the subject. Well-known social scientists focus on three critical areas: social inequalities, knowledge systems, and lifestyles and values. Collectively, they advance

measure of the rate of innovation --research-and-development (R&D) expenditure per employee compared to new patents received per employee -- does not adequately capture a unique feature of SMEs, namely that owners and managers are often themselves innovators. For example, in Japan 52 per cent of SMEs' innovations reported in 1986 were created by employers, whereas in large firms 72 per cent of innovations were created by research technicians. Nevertheless, patchy evidence from Germany, the United Kingdom and the United States indicates that SMEs at least hold their own in terms of innovation compared to large firms. Perhaps most significantly, a recent study indicates that, while the total number of innovations is positively related to R&D expenditures, skilled labour and the degree to which large firms comprise the industry, in innovative industries innovative activity tends to emanate more from SMEs than large firms. This is probably because in industries where large firms dominate, SMEs need to be innovative to survive. There is much information to suggest that in technologies such as micro-electronics, new materials and biotechnology SMEs tend to be in the vanguard of innovation. Small and medium-sized enterprises as exporters. The contribution of SMEs to a national economy from exporting is generally small; for example, in Japan SMEs accounted for only 13 per cent of merchandise exports in 1990.
