I also find that the direction and degree of spillover flow is related to the characteristics of Japanese firms39。s FDI in the United States? Journal of International Economics , Volume 68, Issue 2, 2021, Introduction To what extent does technological knowledge flow across national borders, and by what means are these knowledge flows mediated? These questions have received an increasing amount of attention over the last decade, as leading scholars in international economics have focused considerable research effort on the topic of knowledge A considerable body of theoretical and empirical work has focused on the extent to which imports of manufactured goods could serve as channels of knowledge While less thoroughly explored in formal models, the literature also suggests the possibility of a ―learningbyexporting‖ effect in which firms learn to improve the quality of their products and production processes through contact with more advanced foreign petitors in global export The flow of goods is not the only means through which technological knowledge can flow across national boundaries. An obvious alternative is foreign direct investment. A number of countries have policies that encourage or even subsidize multinational investment. Often, as has been the case in Singapore and Malaysia, these policies are deliberately biased in favor of multinational firms in ―technology intensive‖ industries. Such preferences are based on the view that production and/or research activities undertaken by multinational affiliates within national borders confer ―spillover‖ benefits. In an effort to submit these views to careful statistical tests, a number of scholars have undertaken empirical studies of spillover benefits from FDI. The work of Harrison and her coauthors, which has been particularly influential, has used III7 microlevel panel data drawn from Morocco and Following the basic methodology developed by Aitken and Harrison (1999), Keller and Yeaple (2021) and Haskel et al. (2021) have examined FDI in advanced industrial economies, and Javorcik (2021) has examined FDI in Lithuania. In the previous work, I have examined issues related to the focus of this paper. Branstetter and Nakamura (2021) examined changes in the research productivity of Japanese manufacturing firms over the 1980s and 1990s. As part of that study, we examined the extent to which Ramp。 III6 外文翻譯之二 Is foreign direct investment a channel of knowledge spillovers Evidence from Japan39。有一些其它的政策可能潛在地促進(jìn)跨國企業(yè) 驚醒當(dāng)?shù)夭少?,比如培養(yǎng)商業(yè)氛圍或開發(fā)供應(yīng)商發(fā)展項目會幫廚當(dāng)?shù)厣a(chǎn)者學(xué)會如何滿足外國買家的要求。我們?nèi)孕枰M(jìn)行更多的工作去了解 FDI 流入對東道國的影響。 我們的調(diào)查結(jié)果 證明 FDI 確實(shí)具有外在性,需要予以警惕。我們的調(diào)查結(jié)果與預(yù)期一致,因?yàn)樵谒械姆治鲋形覀冋业搅祟A(yù)期的模型。這部經(jīng)驗(yàn)主義作品說明在發(fā)展中國家負(fù)面競爭效應(yīng)超過了知識溢出的正效應(yīng)。 與垂直效應(yīng)形成對比的是, FDI 的出現(xiàn)對在同一個部門的當(dāng)?shù)仄髽I(yè)的績效有一個負(fù)影響。對每一個部門最好的企業(yè)和差一點(diǎn)的企業(yè)都適用。 前者效應(yīng)的大小在經(jīng)濟(jì)上很有意義 .國內(nèi)外共同所有的項目多增加一個, 供應(yīng)產(chǎn)業(yè)的國內(nèi)企業(yè)的要素生產(chǎn)率增加 %。 與我們的預(yù)期一致,分析結(jié)果說明國內(nèi)外共同所有的項目能夠?qū)ι嫌尾块T有正溢出效應(yīng) ,但是獨(dú)資企業(yè)沒有這樣的溢出效應(yīng)。通過使用 1998—— 2021 年羅馬尼亞公司層面的面板數(shù)據(jù), 檢驗(yàn) 外商獨(dú)資子公司和合資企業(yè)在其 產(chǎn)業(yè)內(nèi)以及提供中間投入品的上游企業(yè)是否有一個不同的溢出范圍。
