两种技术引进方式的直接效应研究--上海市大中型工业企业的微观实证

本文根据上海市大中型工业企业技术引进的实际情况,借助于新古典增长理论的分析框架,研究了技术贸易和FDI两种主要的技术引进方式的直接效应。通过对1998—2003年上海市大中型工业企业的一个随机样本面板数据的计量经济检验和分析,得到几点主要结论:第一,三资企业的劳动生产率和全要素生产率比内资企业高,造成这一差距的主要原因是随FDI转移的无形技术和其较高质量的人力资本;但是三资企业内部转移的有形技术对其技术水平的提高没有显著的贡献。第二,国有企业的有形技术购买对其劳动生产率和技术水平的提高都具有显著的正面影响,而且促进作用强烈依赖于企业的科技人力资源。第三,我们没有发现其他内资企业引进的技术对其生产效率的提高发挥出显著作用。本文从实证研究的结果判断,近六年来上海市三资企业的技术先进性不明显,R&D投入强度不足,各种所有制类型的企业普遍重技术引进轻消化吸收,企业的科技活动机制上的缺陷,都对技术转移效果产生了一定的影响。     

Open technology innovation activity and firm value: evidence from Korean firms

Despite the importance of Open Technology Innovation Activity (OTIA) for firm value, the literature investigating effects of OTIA announcements of developing country firms is not known in international academic circles. Our study using an event study approach examines the effects of OTIA (technology import and joint R&D) announcements of firms in Korea, one of the leading developing and highly innovative countries. We find that the announcements of OTIA produce positive average abnormal returns. Interestingly, unlike the prior studies on developed country firms, OTIA with firms in the homogenous industry leads to greater firm value than that involving firms in heterogenic industries. This implies an importance of a technological fusion with external firms in different industries for value of developing country firms. In addition, this article finds no home bias that a nationality of partner firms is not essential for the relation between OTIA and value of firms.     

Productivity dynamics in Japan and the negative exit effect

Previous studies on productivity dynamics in Japan have suggested that one of the reasons for sluggish productivity growth in the economy was that highly productive firms exit the market, giving rise to a negative exit effect. This study is the first using census data and a large-scale micro data set to verify the negative exit effect in Japan. We conduct analyses of productivity dynamics using the micro data. The results show that there is indeed a negative exit effect in Japan and that this is driven mainly by the exit of a small number of highly productive firms.     

中国技术进步源泉的比较：自主创新和技术外溢——基于阿尔蒙多项式分布滞后模型的研究

在内生增长理论中,技术溢出和自主创新都是技术进步的重要源泉。通过Granger因果检验发现,国内外研发和国内专利与中国劳动生产率和全要素生产率之间存在因果关系。利用阿尔蒙多项式分布滞后模型对国内外研发、国内专利与中国劳动生产率以及全要素生产率之间的关系进行比较研究发现,国外研发对中国劳动生产率和全要素生产率增长的促进作用远大于国内研发和专利,国际技术溢出是中国技术进步的主要源泉,劳动生产率比全要素生产率能够更好地度量中国技术进步。     

Firm heterogeneity in productivity across Europe: evidence from multilevel models

This paper analyses the Total Factor Productivity (TFP) heterogeneity of a sample of manufacturing firms operating in seven EU countries (Austria, France, Germany, Hungary, Italy, Spain and the UK). TFP data refer to 2008. The empirical setting is based on the multilevel modeling which provides two main results. Firstly, we show that TFP heterogeneity is largely due to firm-specific features (85% of TFP variability in the empty model). Interestingly, we find that some key-drivers of firm performance (size, family management, group membership, innovations and human capital) are significantly related to TFP, but do not, on the whole, absorb much of firm TFP variance, implying that differences in productivity are due to notable yet unobservable firm characteristics. Secondly, as far the role of localization is concerned, we demonstrate that the country effect is more influential than region effect in explaining individual productivity. Net of the country effect, the localization in different European regions explains about 5% of TFP firm heterogeneity. When considering the case of three individual countries, France, Italy and Spain, location in different regions explains 5.3% of TFP heterogeneity in Italy, while this proportion is lower (3.6%) in France and higher (9.9%) in Spain.     

外商直接投资与中国技术进步的实证分析

在不同的阶段外商直接投资的作用是不同的。从1991—1994年的4年间,外商直接投资对中国技术进步的直接效应和间接效应都是不明显的。从1996—2003年的8年间,外商直接投资对中国经济增长做出了直接贡献,但外商直接投资所带来的技术进步而产生的技术外溢是有限的,因而外商直接投资的间接效应是不明显的。外商投资参与度对劳动生产率提高的影响越来越大,外商直接投资在劳动生产率提高中的作用越来越重要。     

FDI, domestic capital and economic growth: Evidence from panel data at China’s provincial level

Based on panel data at the provincial level in China, this paper found that direct effects foreign direct investment (FDI) had on economic growth were of insignificance. However, through improving technical efficiency and “crowding” in domestic investment, FDI produced positive effects on China’s economy. The state sector still played a major part in the total fixed investment, therefore, direct effects on growth were significant. Although private sector was increasingly important for the whole economy, it had no direct influences on economic growth. Meanwhile, neither the state sector nor private sector made contribution to the improvement on technical efficiency. __________ Translated from Shijie Jingji Wenhui 世界经济文汇 (World Economic Papers), 2006, (4): 27–43     

Firm innovation and productivity in Europe: evidence from innovation-driven and transition-driven economies

This article examines the links between firm innovation and firm productivity performance across a range of European economies, and in particular, we explore the differences between countries which are in transition from efficiency-driven to innovation-driven with those which are primarily innovation-driven economies. We employ an endogenous-switching technique to explore micro-economic survey-based data from both innovating and noninnovating firms. The model allows us to construct counterfactual scenarios which overcome problems of self-selection in the data. Some of the findings provide support for the traditional patterns previously found in the innovation literature, in which innovation efforts and investments in physical and human capital are found to be important for product and process innovations in manufacturing and service firms and across economy types. Our counterfactual analysis also allows us to outline a rationale for policy intervention towards noninnovating firms as well as innovating firms depending on where the transitional heterogeneity effects are greatest.     

Export and import composition as determinants of bilateral trade in goods: evidence from Russia

Conventional theory and several empirical studies state that incomes and exchange rates are the key determinants of the trade balance. Here, we argue that export and import composition are also key explanatory variables because some goods are inelastic and/or with a high added value, directly and indirectly affecting income and price elasticities and trade balance. Thus, if exports and/or imports significantly consist of price inelastic products, then, a positive and a negative effect, respectively, should be expected on the trade balance. Using bilateral trade data and dynamic panel models, we found that the ratio of exports of crude petroleum and natural gas (price inelastic goods) to total exports is significantly and positively associated with the Russian trade balance in goods. For its part, Russian imports of high-tech goods (income elastic and price inelastic with a high added value) show a negative association. The goods balance of Russia also responded to changes in relative income, but there is only weak evidence of reactions to changes in the exchange rate. These findings partially explain the persistent surplus in the Russian trade balance and current account.     

On the spillover effect of China's outward FDI in Germany

The outward foreign direct investments of China have been steadily decreasing since the 21st century up to a point where the country has begun to passively accept direct investments from outsiders and holding off its active investments in expansion. Such trend has motivated scholars to examine the effects of countering investment. In line with these efforts, this study uses German firm-level data from the Academus database to examine the investment of China in Germany as its research object. Using the new investment review system as a quasi-natural experimental event construction instrument variable, an empirical analysis of how the investments of China in Germany can produce spillover effects on the productivity of German firms highlights the significant and robust effects of such investments as well as their negative horizontal and backward vertical spillover. Such negative spillover effect is particularly salient among German industries with low product heterogeneity, import and export intensities, and R&D levels of China.

China wage inequality: the role of trade and technology

This article empirically investigates the impact of international trade and technical change on skill premia for a panel of 28 manufacturing sectors in China over the period 2002–2011. The results find that the effect of changes of the share of SOEs is twofold. First, the contraction of SOEs promoted productivity growth, and the promoting effect was skill-biased, which tended to increase the skill premia in China. Second, the drop of product prices resulting from falling SOEs share was more magnificent in skill-intensive industries, which helped to mitigate wage inequality through product prices. The accounted-for portion of price changes by productivity growth was skill-biased, significantly raising skill premia through product prices. However, the portion of price changes accounted for by foreign price was unskill-biased, and world price competition diminished the growing income disparity in China.     

Real wages and labor-saving technical change: evidence from a panel of manufacturing industries in mature and labor-surplus economies

Recent theories have provided a persuasive account of a key stylized fact of mature economies: the common long-run trends of average real wages and labor productivity, and the ensuing stationarity of functional distribution. Central to these theories is the notion of directed technical change, which claims that a rise in labor costs sparks the adoption of labor-saving innovations. This paper empirically examines a core prediction of these theories, namely that shocks to functional distribution elicit compensatory adjustments in real product wages and labor productivity. Using two disaggregated data-sets of manufacturing industries (EU-Klems and Unido), I find evidence of cointegration and two-way, long-run Granger causality between these two variables. These findings suggest that directed technical change is indeed key for producing stationarity in functional distribution, and they complement the recent empirical literature on distributive cycles and productivity growth. Preliminary evidence from the Unido data-set also suggests the importance of directed technical change in developing countries. To illuminate the empirical procedure, I present a theoretical model of growth and distribution with directed technical change.     

Regional foreign direct investment and technology spillover: evidence across different clusters in India

This paper examines whether there exist productivity spillovers from foreign direct investment (FDI) to domestic firms at the regional level, using firm-level panel dataset covering 22 manufacturing industries in India from 2000 to 2012. In order to estimate the productivity spillovers from FDI at the regional level, we select 10 industrial clusters across 4 regions in India. In estimating productivity, we control for a possible simultaneity bias by using semi-parametric estimation techniques. We find that local firms benefit from horizontal and vertical FDI, but the benefits from the latter are found to be substantially stronger. The absorptive capacity of domestic firms is highly relevant to harvest the spilled technology from foreign-owned firms. Furthermore, we find that domestic firms belonging to high-technology industries benefit more from FDI at the regional level. We also find that market concentration is a crucial conduit for firm innovation, technological upgradation, and having a direct effect on local firm total factor productivity.     

外商直接投资、外包对中国制造业劳动需求弹性的影响

中国制造业行业的FDI与外包具有提高中国制造业劳动需求弹性的作用,这一影响是通过替代效应与产出效应两条渠道实现的。FDI流入与外包可能通过提高劳动需求弹性对中国制造业部门劳动者产生较大压力。

Productivity change and externalities: empirical evidence from Hungary

This paper contributes to the analysis of the impact of externalities on the host country’s total factor productivity by taking into account different dimensions of spillover effects. Namely, engagement in exporting and foreign ownership is generally perceived as being beneficial to individual firms and the economy as a whole. The approach used in the current research accounts for different internal as well as external factors that individual firms face and evaluates the effect on changes in productivity, technology as well as the efficiency of domestic firms. The empirical analysis focuses on Hungary. While the country leads the group of post-socialist countries in the amount of attracted foreign direct investments (FDI) the effect of this policy on the economy remains unclear. The research finds that different externalities play a different role in productivity, technological and efficiency change in different types of firms and sectors of the economy.     

Outward foreign direct investment and domestic innovation performance: evidence from China

The existing literature has explored the existence of reverse technology spillover through outward foreign direct investment (OFDI), which means domestic firms improve their technological innovation and productivity due to overseas investment activities. This paper aims to examine how the host country affects reverse technology spillover from OFDI. The findings show domestic innovation performance (DIP) is positively related to OFDI in developed countries while it is negatively related to OFDI in transitional and emerging markets. It is also found that financial development and human capital weaken the positive relationship between OFDI in developed countries and DIP and also weaken the negative relationship between OFDI in transitional and emerging markets and DIP. These results are further confirmed through robustness checks.     

Exploring the Existence of Local and Global Knowledge Spillovers:Evidence from Plant‐Level Data*

We investigate the existence of local (within‐country) and global (between‐country) knowledge spillovers within a single analytical framework. Our study is based on a detailed database of domestically owned and foreign‐affiliated manufacturing plants located in Ireland. The results of our econometric analysis show that domestically owned plants benefit from the research and development (R&D) activities of other domestically owned plants, as well as from R&D activities conducted in the country of origin of foreign‐owned plants through their presence in Ireland. A fundamental difference between such locally generated and locally transmitted global spillovers appears to be that the latter are much less constrained by distance decay effects.
