融资约束与企业出口行为:基于工业企业数据的经验研究

采用2000—2007年的3万多家工业企业数据,本文构造了包括内源融资、商业信贷以及企业信用特征等变量的企业融资约束综合指标。基于Heckman选择模型的经验研究表明,企业融资状况的改善不仅能提高企业出口的概率,而且对其出口规模也有重要影响。研究还发现融资状况改善对外资企业出口影响最显著;与国有企业相比,民营企业虽受到更严重的融资约束,但其出口表现并未更差。此外,融资状况改善对那些高外源融资依赖度行业的企业出口具有更明显的促进作用。     

OWNERSHIP AND SECTOR PERFORMANCE IN PRESENT-DAY CHINA: A REGIONAL STUDY

Abstract.  Using the latest provincial data to investigate the different performance of different ownership sectors, we found that there are significant differences in both production technology and the determinants of performance at provincial level between state controlling sectors, collectives, domestic private enterprises, Hong Kong, Macau and Taiwan funded firms and foreign invested firms. Cobb–Douglas functions fit the production technologies of the state-controlled, collective and overseas Chinese funded sector very well. However, the production technologies of the domestic private and foreign funded sector are better represented by translog function. In addition, the determinants of economic performance change substantially from one ownership sector to another.     

Export sophistication and economic growth: Evidence from China

We consider the effect of export sophistication on economic performance by appealing to regional variation within one single country (China) over the 1997-2009 period. We find evidence in support of Hausmann, Hwang and Rodrik (2007), in that regions specializing in more sophisticated goods subsequently grow faster. We find substantial variation in export sophistication at the province and prefecture level, controlling for the level of development, and that this sophistication in turn drives growth. Our results suggest that these gains are limited to the ordinary export activities undertaken by domestic firms: no direct gains result from either processing trade activities or foreign firms, even though these are the main contributors to the global upgrading of China's exports. As such, the extent of assembly trade and foreign entities should be distinguished in order to measure the true movement in a country's technology and the contribution of exports to economic growth.     

FOREIGN ENTRY LIBERALIZATION AND EXPORT QUALITY: EVIDENCE FROM CHINA

This paper examines the impact of foreign entry deregulation in China on the export price and quality of manufacturing firms through input–output linkage. We create a unique dataset describing the extent of regulatory control over foreign entry across approximately 900 industries covering all primary, manufacturing and services sectors. Results suggest foreign entry deregulation encourages firms to improve product quality and increase export prices. Deregulation in the manufacturing sectors has more impact on downstream export price and quality, compared with services sectors. Moreover, firms having larger imported inputs benefit more from foreign entry deregulation. These effects are robust to alternative specifications. (JEL F1, D2, O2)     

THE NUMBER OF FIRMS AND THE POLITICS OF STRATEGIC TRADE POLICY

Incorporating home firms' lobbying in a country into a third market model of oligopoly, this paper studies how such lobbying affects the government's strategic export policy scheme. We pay special attention to the home firms' lobby formation and its effect on domestic welfare. The home firms can organize a lobby more easily when the number of their rival foreign firms is larger than that of them, and/or when the government is overly concerned with political contribution relative to domestic welfare. The strategic export policy under lobbying cannot improve the domestic welfare, which depends on the number of firms, the government's concern about political donation and the level of socially wasted lobbying costs.     

Public Stackelberg Leadership in a Mixed Oligopoly with Foreign Firms

This is the first paper to consider a mixed oligopoly in which a public Stackelberg leader competes with both domestic and foreign private firms. The welfare maximising leader is shown to always produce less than under previous Cournot conjectures. Introducing leadership also alters previous public pricing rules resulting in prices that may be either greater than or less than marginal cost depending on the relative number of domestic firms. Furthermore, entry of a foreign firm will increase welfare only when the relative number of domestic firms is small, but that share is shown to be larger than has been indicated without leadership. Unlike previous models, the influence on public profit of a foreign acquisition is ambiguous and is related to the relative number of domestic firms. Finally, the consequences of privatisation are shown, for the first time, to depend on the relative number of domestic firms.     

Risk sharing and export performance with firm heterogeneity

We investigate how market uncertainty affects the export performance of a firm through financial frictions. We first extend Melitz's (2003) heterogeneous firm trade model by incorporating demand shocks, linking the demand uncertainties to the financing costs of firms. In this extension, the default probability is endogenously determined by a firm's productivity and demand uncertainty. Hence, firms with higher productivity or lower market uncertainty are offered lower interest rates and thus show better export performance. As an application, we also show that a risk-sharing mechanism, that pools default risk for a certain group of firms, lowers the default risk. This mechanism allows banks to charge lower interest rates to the member firms and therefore ultimately improves their export performance in both extensive and intensive margins. We find a real-world example of such a mechanism from business groups in Korea. Using Korean firm-level data, we show that the more diversified the business group, the greater the likelihood that its member firms export and the bigger their export revenues. We also show that our results are robust to alternative explanations for Korean business groups’ export competitiveness.     

Trends in Disaggregated Import and Export Prices in Europe: Implications for the Trade and Wages Debate

We consider carefully the evidence from traded prices (as proxied by unit values) concerning the transmission of the effects of globalisation to domestic labour markets. Using standard index number techniques we decompose changes in sectoral import and export unit values into movements due to changes in pure prices of the initial bundle of goods imported or exported and changes due to upgrading of that bundle. Looking at the imports of selected European countries of textiles, clothing and footwear relative to engineering products we find evidence of strongly falling pure prices of the unskilled intensive products relative to the skilled products in the 1980s. This reinforces the view that import prices can capture the impact of globalisation in terms of falling relative prices for products produced with the intensive use of unskilled labour. However, the trends are not common across all the unskilled sectors; footwear is clearly an exception. In the absence of detailed domestic data, we look for reactions by domestic firms to increased import competition in movements in the price and composition of exports. We find evidence of stiff price competition from imports being associated with similar movements in export prices and no support for the view that import competition from low–wage countries has led to upgrading of the quality of exports.     

Why does China protect its labour‐intensive industries more?*

China's tariff structure favours labour‐intensive sectors, and this is at odds with traditional theory of comparative advantage. The paper argues that tariffs in China are a mechanism for protecting technology‐backward domestic – especially state‐owned enterprises (SOEs) from competition technology‐advanced foreign enterprises producing in China. With relatively integrated labour markets and cross‐firm technology differences, SOEs’ subsistence is supported by subsidized credit and limited access of foreign firms’ local production to tariff‐protected domestic markets. Labour market integration and capital subsidies increase the relative cost of labour in SOEs compared to their foreign competitors, hurting more domestic firms in industries that use labour more intensively. Restrictions to FIEs’ (foreign‐invested enterprises) access to tariff‐protected product markets, which protect more labour‐intensive industries, compensate for the greater cost disadvantage of SOEs in labour‐intensive sectors.     

Market structures in small open economies: Evidence from Denmark

This paper provides some stylized facts about market structure in Denmark, a country exhibiting high rates of exports and imports as is common in small developed economies. Utilizing disaggregated data at the firm-product level for manufacturing industries, we highlight the widespread presence of industries that are neither purely oligopolistic or monopolistically competitive; rather, they contain a few domestic leaders with numerous firms having insignificant domestic market shares. We also document that, relative to the latter type of firms, leaders have greater labor productivity, are more capital intensive, and pay higher wages; additionally, they are more likely to export and import, although they exhibit a greater domestic intensity relative to exporters with negligible domestic market shares. Finally, through a model of leaders and followers, we investigate how leaders can benefit from acting strategically against small firms and quantify its potential impact on industry outcomes through a numerical exercise.     

When does funding research by smaller firms bear fruit?: Evidence from the SBIR program*

This paper evaluates whether the relative concentration of funding for small, research-oriented firms in a small number of high-technology industries is related to differences across industries in the appropriability level facing small firms. We exploit a novel test based on the relationship between industry-level private venture financing and the performance of government-subsidized R&D projects. If industries differ in their appropriability level, then private funding and subsidized project performance should be positively correlated. Our principal finding is that subsidized project performance is higher in industrial segments with higher rates of private venture capital investment. Industrial sectors therefore seem to differ in the degree of appropriability and this variation helps explain why venture capital is concentrated. * The latest version of this paper is available at http://www.mbs.edu/home//jgans/research.htm     

Trade Policy and Productivity Growth in OECD Manufacturing *

Trade liberalization may promote economic growth in a number of ways, including by accelerating the rate of technological change. Firms that face more intense import competition may be spurred to greater rates of innovation; firms which export may absorb new technologies through their contact with international markets. This paper examines evidence on trade policy and productivity growth for a sample of thirteen OECD countries and including eighteen manufacturing sectors, using data primarily from the 1980s. Within individual sectors, there are strong productivity convergence effects within the OECD. After controlling for convergence, we find a positive association between high rates of productivity growth and low tariffs, and between high productivity growth and strong export performance. We found no particular association between high productivity growth and import penetration. The results are consistent with the possibility of positive linkages between trade liberalization and accelerated productivity growth. [F1, O4]     

Interrelationship among foreign presence,domestic sales and export intensity in Chinese manufacturing industries

Using panel data on six Chinese manufacturing industries over the period 2005–2007, this article explores the interrelationship among foreign presence, domestic sales and export intensity of local firms. We find that the domestic sales and exports are complementary for local firms in China’s pharmaceutical industry, whereas in the case of the textile, transportation equipment, beverage, communication equipment and general equipment manufacturing industries, domestic sales and exports are substitutes. An increase in the average domestic sales increases foreign presence in all industries. The same applies to an increase in the average export intensity. An increase in the level of competition in China’s textile industry increases the export intensity as well as domestic sales of local textile firms. However, an increase in the level of competition in the pharmaceutical industry leads to a very large decrease in export intensity of local pharmaceutical firms. In the case of China’s transportation equipment manufacturing industry, an increase in the level of competition decreases domestic sales of local firms. Furthermore, an increase in the firm size increases domestic sales of Chinese firms in all six manufacturing industries.     

创新与出口间因果关系分析——基于中国高技术产业企业数据的实证研究

使用1999—2009年我国18万家规模以上高技术产业微观企业数据,采用倾向得分匹配方法控制内生性问题,分析了企业创新与出口之间的因果关系。以产品创新衡量企业创新的估计结果表明,企业创新与出口间存在明显的因果关系:企业创新使其出口概率平均增加14%以上,企业出口使企业创新概率平均提升超过8%,从创新到出口、从出口到创新的因果关系方向均显著。区分出口强度和企业类型的估计结果显示:这种因果关系随着出口强度的增大而减弱;内资企业的创新对其出口的影响要大于外资企业;外资企业的出口对其创新的影响要大于内资企业。以研发衡量企业创新后也得到了类似结果。     

Is the effect really so large? Firm‐level evidence on the role of FDI in a transition economy1

Foreign subsidiaries usually perform better than domestic enterprises, but selection effects have been acknowledged in the literature. This article contributes by quantitatively evaluating the size of the selection effects and direct effects of FDI entry. We use a large panel of firm‐level data from Poland and match foreign‐owned firms to a control group of non‐foreign‐owned companies and analyse various performance indicators. In terms of efficiency measures, between 50 and 70 percent of the foreign affiliates advantage may be attributed to direct ownership effects. However, in the case of export intensity, the majority of the differential between the domestic companies and foreign subsidiaries is attributable to selection effects: MNEs choose export‐oriented companies and sectors.     

EU accession and foreign-owned firms in Bulgaria

Bulgaria signed the European Union accession treaty in 2005. Accession caused an increase in the volume of inward foreign direct investment flows (IFDI). We analyse World Bank BEEPS firm-level data for 2007 to understand the characteristics and performance of foreign firms in Bulgaria. Regression analysis reveals that foreign firms are larger, have lower capital-to-labour ratios, are more likely to export and are more likely to locate in Sofia. However, foreign firms have had limited success in Bulgaria. They do not exhibit higher sales growth and, in manufacturing, carried out lower capital investment in machinery than domestic firms. The numbers of visits from tax officials is the same for domestic and foreign firms in manufacturing, and lower for foreign firms in the service sector. However, firms with higher exports-to-sales ratios and higher absolute sales were subjected to a higher number of visits from tax officials. These findings suggest that a range of institutional challenges remain for foreign firms in Bulgaria.     

Who Benefits from Foreign Direct Investment in the UK?

The presumed higher productivity of foreign firms and resulting spillovers to domestic firms has led governments to offer financial incentives to foreign firms. We investigate if there is any productivity or wage gap between foreign and domestic firms in the UK and if the presence of foreign firms in a sector raises the productivity of domestic firms. Our results indicate that foreign firms do have higher productivity than domestic firms and they pay higher wages. We find no aggregate evidence of intra‐industry spillovers. However, firms with low productivity relative to the sector average, in low‐skill low foreign competition sectors gain less from foreign firms.     

Foreign firm entry in an open economy: the case of Portugal

The purpose of this paper is to analyse the entry process of foreign direct investment (FDI) in Portuguese industrial sectors. Portugal presents an interesting case where firms enter to take advantage of export opportunities. The results suggest that foreign firms possess the ability to overcome existing entry barriers that affect domestic firms. Apparently, foreign firms have different expectations about profitability than domestic firms, possibly due to foreign firms’ export-orientation to the rest of the European Union (EU). They appear to desire industries where other foreign firms have clustered. Above all, it appears that these foreign firms enter industries to exploit Portugal's chief location advantage in Western Europe: low wages. Portugal's FDI experience is relevant to other countries that have opened their economies to greater trade and investment and attracted export-oriented firms.     

Effects of Chinese Imports on Relative Wages: Microevidence from Chile*

The increasing prominence of China in world trade raises important questions about the impact of this on importer countries. In this paper, we address the issue of how import competition from China has affected relative wages in the Chilean manufacturing industry. Using plant‐level data for the period 1996–2005, we find that increasing imports from China have depressed relative wages in sectors with higher Chinese‐import penetration. Our results show a significant reduction of relative wages, between 4 and 25 percent, for those sectors that have experienced the largest increases in Chinese imports. We also find that this effect is particularly strong for small firms, while large firms are unaffected.
