经济集聚中马歇尔外部性的识别-基于中国制造业数据的研究

本文提出了识别经济集聚中马歇尔外部性的方法,并将其应用于中国制造业数据。通过考察制造业集聚水平和产业间专业化分工的协同演进过程,本文一方面发现两者具有替代关系,验证了马歇尔外部性是经济活动空间集聚后果的理论假说;另一方面证实了马歇尔外部性是推动中国制造业空间不断集聚的基本因素。本文还发现市场化改革是实现马歇尔外部性的积极力量。本文的结论为我国企业选址、产业布局和城市发展政策提供了依据。     

产业政策中的资金配置:市场力量与政府扶持

产业政策具有重要的国家战略意义,如何有效引导经济资源流向政策支持产业,是产业政策发挥成效的关键.现有相关研究未深入考察经济资源在扶持行业之间及行业内部配置的规律,而且没有综合探讨不同资金配置的关联.文章考察了市场力量与政府扶持两种机制如何引导产业政策下的资金配置.研究发现,产业政策支持的企业获得了更多的债务融资和政府补助.其中,债务融资更多地流向了成长行业中规模较大的企业,政府补助使成长行业中的小规模企业和成熟行业中的大规模企业受益更多.研究结果表明,市场看重企业的增长机会,政府补助则会顾及当前成长性较弱而相对不受市场青睐的企业,对产业政策下的市场化资金配置起到了补充作用.文章的研究为如何协调市场机制和政府扶持两种力量提供了一定的借鉴.     

Market thickness,sunk costs,productivity, and the outsourcing decision: an empirical analysis of manufacturing firms in France

Abstract This paper presents an empirical analysis of outsourcing behaviour by French manufacturing industries. It focuses on the effects of market thickness, sunk costs, and the productivity of firms on the outsourcing decision. I estimate a dynamic probit model where outsourcing decision is linked to past outsourcing behaviour. The results show that outsourcing is a persistent strategy adopted by large firms and suggest the presence of significant sunk costs associated with outsourcing. The results also show that market thickness reduces search costs and enhances the establishment of outsourcing relationships.     

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.     

我国企业规模经济现状及实现途径

目前,我国主要产业的企业规模普遍偏小,产业集中度过低,生产要素配置过于分散,缺乏规模经济。合理扩大我国制造业的企业规模,实现规模经济是提高我国工业竞争力的当务之急。以横向联合方式为主的企业购并是短期内实现规模经济的有效途径。     

International Trade, Technological Development, and Agglomeration

The paper focuses on how localized dynamic external economies of scale may cause uneven technological development internationally, and encourage regional agglomeration of industries. Location-specific technological progress depends on the absolute number of local innovating firms, and the relative number of innovating firms; i.e., the share of economic activity in a region that takes place within the innovating sector. The creation of industrial clusters contributes to explaining regional specialization, factor prices and welfare, and it appears that the critical size of a region regarding its ability to sustain an industrial cluster depends on whether factors of production are internationally mobile.     

中国制造业集聚的实证研究：基于企业规模异质性视角

本文基于中国制造业集聚的数据,从企业规模异质性视角出发,检验中国制造业集聚经济效应。首先考察影响制造业集聚的一般因素,然后重点考察了企业规模因素对集聚经济的影响机制。研究发现：除了运输成本优势、劳动力成本等影响制造业集聚的一般因素之外,企业规模异质性也对集聚经济效应产生影响。最后通过构造隐含企业规模因素的集聚经济新变量,对企业规模异质的集聚经济效应进行检验。本文的研究发现,小型企业的专业化经济和竞争效应大于大中型企业。这一结论不仅反映了不同规模企业对制造业集聚影响的差异,也说明了小型企业对制造业集聚的重要性。     

International trade performance and concentration in British industry

This paper reports the results of a cross-sectional analysis for 97 industries at the Minimum List Heading level, of their international trading performance 1970–77 and the influence of industrial structure on this. It is shown that, on average, import penetration increased faster than the export ratio for the industries analysed. Investigation of the relationship between industrial concentration and international trade suggest that in the majority of the analyses, especially where the relation between prior concentration change and subsequent with a performance was concerned, higher or increasing levels of concentration were associated with a weaker international trade performance. On the basis of this it is argued that more attention needs to be paid to international trade as a performance rather than merely a structural phenomenon in industry, the reasons for the relatively disappointing performance need to be investigated in more detail, the risk of a decline in internaional trade performance needs to be taken into account in formulating competition policy, especially with respect to mergers and the investigation of dominant firms.     

Entry,market turbulence and industry employment growth

This paper investigates the relationship between industrial dynamics in terms of firm entry, market turbulence and employment growth. Do entry of firms, the composition of industry dynamics (net entry) and market turbulence (entry and exit) influence industrial employment growth? This paper provides an empirical investigation, using unique data for 42 disaggregated Swedish industrial sectors during the period 1997–2001. It is hypothesised that the importance of entering firms, net entry and market turbulence may differ significantly across industries. A quantile regression method is used in order to detect industrial differences in the response to industrial employment growth. The empirical evidence shows that, on the one hand, firm entry and market turbulence have a positive effect on employment for fast growing industries and that the effect is larger for high growth industries. On the other hand, the composition of industry dynamics in terms of net entry rates has a more dispersed effect across all industries, even though the effect of net entry is larger for high growth industries.     

创新驱动抑或低成本战略——基于融资结构与行业集中度视角的实证检验

融资结构与行业集中度是企业选择创新驱动亦或低成本战略的重要条件。本文以2009-2019年创业板上市公司为研究对象,实证检验融资结构与行业集中度对企业选择上述两种竞争战略的影响。研究表明:(1)负债率越高的企业越偏好低成本战略,而负债率越低的企业越偏好创新驱动战略;(2)相比高集中度行业,在低集中度行业中,负债率高的企业更偏好低成本战略,也更排斥创新驱动战略。本文在此基础上,提出大力发展股权融资以及优化行业竞争环境,以提升企业创新驱动力的政策建议。     

产业政策、创新与制造企业服务化——基于“中国制造2025”准自然实验的经验研究

运用2000—2019年中国上市公司数据库，以2015年“中国制造2025”战略实施作为准自然实验，构建双重差分模型检验产业政策对制造企业服务化的影响及作用机制。结果发现，“中国制造2025”战略能够显著促进制造业服务化率提升。异质性分析表明，与国有企业和外资企业相比，民营企业所受的促进作用更显著；与西部地区企业相比，东部地区企业和中部地区企业所受的促进作用更显著。机制检验发现，产业政策能够通过提高全要素生产率和增加投资激励创新，进而促进制造企业服务化。同时，产业政策可能通过降低投资收益率抑制创新，进而阻碍制造企业服务化。上述结论不仅能够丰富相关文献，而且可以为产业政策有效性争论提供进一步的经验证据。     

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.     

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     

中国沿海地区外资加工贸易模式与本土产业升级:苏州地区的案例研究

苏州的案例表明,中国沿海地区的工业化道路中外资主导的加工贸易模式,尽管在初期能迅速推动当地产业结构的演进,但也极易导致当地产业结构高度化的失衡,形成外资挤压性的二元化发展格局,进一步引发本土企业空心化和边缘化的危机。因此有必要在重视本土企业发展的基础上,大力鼓励和发展本土企业的国际代工,努力提高本土企业的创新能力和发展能力,并实现传统产业和高技术产业的互动和平衡发展。     

Entry,growth, and survival: The new learning on firm selection and industry evolution

This paper tries to shed some light on the seeming paradox posed by the findings in the industrial organization literature that (1) the bulk of firms in an industry are not only very small, but also sufficiently small so that they are operating at a sub-optimal scale of output, and (2) entrepreneurs are apparently not deterred from starting new firms even in industries where scale economies play an important role. A dynamic view of the process of firm selection and industry evolution is that new firms typically start at a very smal scale of output. Because this level of output may be sub-optimal, the firm must grow in order to survive. The empirical evidence supports such a dynamic view of the evolutionary nature of industries. Viewed through a dynamic lens, the often-observed asymmetric size distribution of firms becomes more understandable. The persistence of an asymmetric firm-size distribution skewed towards small enterprises presumably reflects a continuing process of entry into industries and not necessarily the survival of such small and suboptimal enterprises over a long period of time.     

Concentration history and market power in US manufacturing industries

For a 1963–1992 panel of US manufacturing industries, the relationship between seller concentration and both price-cost margins (PCMs) and prices is investigated for industries divided by whether concentration has recently increased or decreased. Regressions of PCM in levels and first differences, and price equations in first differences, establish that the positive effect of concentration on prices and profits is always weaker in industries where concentration has recently increased and always stronger in industries where concentration has recently decreased. These results are attributed to the different endogeneity biases in the two samples. Increasing concentration industries are more likely the ones where leading firms have lowered prices to gain share, while decreasing concentration industries are more likely the ones where smaller firms have lowered concentration by lowering prices. An additional conclusion is that the cost-reducing effects of changes in concentration are greater for increasing concentration industries, meaning that increasing concentration industries have lower price increases compared to decreasing concentration industries.     

The determinants of pollution levels: Firm-level evidence from Chinese manufacturing

Using a large, unique, firm-level dataset from the Chinese manufacturing sector, we study important factors that are related to emission intensity for three pollutants in China – sulfur dioxide, wastewater, and soot. Our main findings are as follows: (1) compared to state-owned enterprises (SOEs), both foreign-owned firms and domestic public-listed firms exhibit less intensive pollutant emissions; (2) firms in regions with less local protection have lower pollution intensity; (3) better property rights protection is negatively correlated with pollutant discharge over and beyond the national standards; and (4) larger firms, firms in industries that export more, and firms with more educated employees pollute less. These results suggest that China should not target foreign firms more harshly in its effort to reduce industrial pollution. Better institutions in the form of more effective law enforcement and lower entry barriers across regional markets are also means of curbing China’s pressing environmental problems during its current stage of economic development.     

Innovation,Skilled Labour,Technology And Performance In Israeli Industrial Firms

A technology index based on R&D, skilled labour and capital vintage was developed and used to characterise industrial firms by technology level, facilitating the analysis of relationships between technology and economic performance at the firm level. The results show that technology-intensive firms are important players in industrial performance, accounting for a disproportionate share of total production. Compared to other kinds of firms, technology intensive firms are larger, more productive, offer higher average salaries, generate a higher value added and a highcr profit per employee and capital. They also tend to operate in more highly concentrated industries and are more involved in external trade. While down-sized as a group, high-tech firms show net job creation during the 11-year period surveyed.     

A fire sale without fire: An explanation of labor-intensive FDI in China

China's labor-intensive industries are characterized by low technology and high competition. The massive inflow of FDI in China's labor intensive industries is inconsistent with the conventional wisdom that FDI should be more prevalent in technology-intensive and low competition industries. To explain this puzzle, we offer a “fire sale” hypothesis: facing severe financial constraints, Chinese private firms give up their equity to form joint ventures with foreign firms in order to obtain financing. Using the garment industry as an example, we find that among domestic firms, the financial constraint index is highest for private firms and lowest for state-owned firms. We further estimate a probit model of joint-venture decisions by private firms. Our results suggest that those private firms with greater financial constraints are more likely to seek foreign joint ownership. The effect of financial constraints on joint venture decision is both statistically and economically significant.     

银行风险偏好对企业发展影响的实证研究

从行业层面和企业层面实证研究了银行信贷选择对行业和企业发展的影响。结果发现:在行业层面,银行偏好于固定资产比率较高的行业,因此在信贷资源较为紧张的地区,固定资产比率较高的行业会发展得较好,可见长期内银行选择会影响一个地区的产业结构;在公司层面,银行偏好于行业中固定资产比率较高的企业,而企业为了获得信贷资源也会调整其发展策略,倾向于积累固定资产。指出:中国应该大力发展非银行融资渠道,减弱金融系统对经济发展的扭曲。
