o domestic investment. This effect, however, seems to be less robust than our other findings. Some caution must be exercised, however, in the interpretation of the size of the effect on economic growth of FDI. Our data measures the international flow of resources for foreign direct investment, as recorded in balance of payments statistics. This is, however, only part of the resources invested by a multinational firm, because some part of the investment may be financed through debt or equity issues raised in the domestic market. Thus, our measure of FDI underestimates the total value of fixed investment made by a multinational firm and the coefficients on FDI may be proportionally overestimated. To the extent that this bias in the measure of FDI is uniform across countries and over time, the qualitative results are not affected. Finally, the results of this paper suggest some directions for further research. The results suggest that the beneficial effects on growth of FDI e through higher efficiency rather than simply from higher capital accumulation. This suggests the possibility of testing the effect of FDI on the rate of total factor productivity growth in recipient countries. In addition, given the robustness of the effect of interactions between human capital and FDI, it might be interesting to explore the effects of FDI on the level of human capital. As we have argued above, FDI is a vehicle for the adoption of new technologies, and therefore, the training required to prepare the labour force to work with new technologies suggests that there may also be an effect of FDI on human capital accumulation. 譯 文: 外商直接投資怎樣影響經(jīng)濟的增長 摘要 我們利用過去二十年里從工業(yè)國家到 69 個發(fā)展中國家的外商直接投資數(shù)據(jù)流動,通過多個國家回歸框架測試了外商直接投資( FDI)對經(jīng)濟增長的影響。 in addition, we would not expect the outflow of foreign direct investment to involve a similar negative growth effects for the source country (loss of knowledge). In the second place, in our framework, foreign direct investment flows from industrialized to developing countries to close the technological gap. Foreign direct investment taking place between countries with roughly the same level of technological development may respond to a large extent to other factors, including global firm strategy and market peration, or to allow firms to circumvent trade restrictions and offset other advantages accorded to domestic producers. This type of foreign direct investment flows may not be expected to display higher than average productivity. For this reason we focus only on foreign direct investment received by developing countries. And furthermore, since flows of foreign direct investment between developing countries may also respond to factors other than the technological gap, we also exclude those flows. Therefore, the OECD measure of foreign direct investment, while having a partial coverage, appears to be the most appropriate for our purposes. These data are available on a yearly basis from 1970. National accounts data, such as the growth rate of ine, initial ine and government consumption, are all taken from Summers and Heston (release of June 1993) which provides data up to 1989. This allows us to consider a 20year period for the empirical investigation. The growth rate measure is the average annual rate of per capita real GDP over each decade, 1970–79 and 1980–89. Government consumption is measured by the average share of real government co
