中国工业产业结构与企业技术研发行为的实证分析   总被引:3,自引:0,他引:3  
产业结构升级一直是我国经济学界所关心的一个问题,工业产业的升级更是一个众所关注的焦点。本文在前人研究的基础上,利用中国工业产业数据,采用了经典的SCP范式模型.对熊彼特的两个经典假说进行了验证。发现竞争与企业利润同时对企业研发具有促进作用.熊彼特两个相互矛盾的结论同时得到了支持。通过对应分析,我们对中国工业内产业不同特点和企业不同特点进行了归类,提出国有企业在不同行业的产值比重是导致了这两个看似矛盾的结论同时并存的原因。  相似文献

This paper studies incentives to develop advanced pollution abatement technology when technology may spillover across agents and pollution abatement is a public good. We are motivated by a variety of pollution control issues where solutions require the development and implementation of new pollution abatement technologies. We show that at the Nash equilibrium of a simultaneous-move game with R&D investment and emission abatement, whether the free rider effect prevails and under-investment and excess emissions occur depends on the degree of technology spillovers and the effect of R&D on the marginal abatement costs. There are cases in which, contrary to conventional wisdom, Nash equilibrium investments in emissions reductions exceed the first-best case.  相似文献

Permit markets lead polluting firms to purchase abatement goods from an eco‐industry which is often concentrated. This paper studies the consequences of this sort of imperfectly competitive eco‐industry on the equilibrium choices of the competitive polluting firms. It then characterizes the second‐best pollution cap. By comparing this situation to one of perfect competition, we show that Cournot competition on the abatement good market contributes not only to a nonoptimal level of emission reduction but also to a higher permit price, which reduces the production level. These distortions increase with market power, measured by the margin taken by the noncompetitive firms, and suggest a second‐best larger pollution cap.  相似文献

Unless an active environmental policy exists, firms have no incentive to engage in abatement or environmental R&D so policy design is of paramount importance. This design heavily depends on the way R&D spillovers operate. There are two distinct types of R&D spillover: output spillover and input spillover. An input spillover operates on the expenditure toward pollution reduction, whereas an output spillover manifests as the achieved abatement. Under optimal emissions taxation, significant differences arise due to this distinction, in particular, when the spillover operates on R&D inputs. In an oligopolistic setting, the result is higher R&D expenditure, but also higher aggregate emissions and, consequently, higher emissions taxes. By contrast, when spillovers occur in R&D output, there is a U‐shaped relationship between the optimal tax and the spillover, showing a trade‐off between the optimal tax rate and spillovers when these are low. In terms of the relative effectiveness of different R&D organization setups, combining emissions taxes with R&D cooperation, this paper shows that under low levels of R&D spillover R&D cooperation gives higher emissions reductions, whereas when spillovers are high this is not the case.  相似文献

This paper addresses the issue of environmental policy instrument choice for achieving deep emission reductions in the industrial sector. Specifically, it provides: (a) a theoretical and empirical review of the conditions under which performance standards can provide efficient incentives for deep emission reductions and technology adoption; and (b) an analysis of the design and the outcomes of the standards-based regulation of industrial pollutants in Sweden during the period 1970–1990. Our empirical findings suggest that the Swedish regulatory approach comprised many key elements of an efficient policy-induced transition towards radically lower emissions in the metal smelting and pulp and paper industries. The regulation relied solely on performance standards, thus granting flexibility to firms in terms of selecting the appropriate compliance measures. These standards were implemented in combination with extended compliance periods. R&D projects and the new knowledge that was advanced incrementally in interaction between the company, the environmental authorities and research institutions provided a direct catalyst to the regulatory process. In these ways the Swedish regulatory approach provided scope for creative solutions, environmental innovation, and permitted the affected companies to coordinate pollution abatement measures with productive investments.  相似文献

We compare two common government R&D support programs, R&D tax credits and direct R&D grants. To study their effectiveness and the extent to which their design matters, we analyze these programs within a dynamic equilibrium model of imperfectly competitive industries. Adopting comprehensive welfare measures that take into account government, producer and consumer surpluses, we find that both schemes exhibit positive social returns. Mid-range R&D-intensive sectors exhibit higher social returns than either high or low R&D-intensive sectors. Both incentive schemes generate positive measures of R&D input additionality of magnitudes consistent with empirical R&D research. However, R&D grants that require firms to allocate subsidy funds to R&D spur less R&D than a more flexible R&D tax credit. Subsidy schemes can even induce competing firms to over-spend on R&D, generating negative producer surplus and possibly negative social returns.  相似文献

Confronting competitive environment, enterprises differentiate their product by promoting their R&D or marketing capacities. Scholars have verified that there is a direct relationship and a deferred effect between R&D expenditures and firm performance, but that there exists an inconsistency between marketing expenditures and firm performance. However, previous studies have neglected to analyse and compare the impact of corporate R&D and marketing investment on performance, and also ignored the moderating effects of different industry characteristics and investment densities. The study attempts to fill the gap by constructing a model to accommodate all these factors. The empirical results indicate that R&D and marketing expenditures have a positive impact on enterprise operating performance, and that there is a longer deferred effect in R&D expenditures than in marketing expenditures. By investing in R&D expenditures, manufacturing enterprises can increase their performance more than in service enterprises, and electronic enterprises can improve their performance compared with other types of firms. Finally, investments with higher R&D density can result in a higher performance.  相似文献

We study optimal pollution abatement under a mixed oligopoly when firms engage in emissions‐reducing research and development (R&D) with imperfect appropriation. The regulator uses a tax to curb emissions. Results show that in a mixed oligopoly, the public firm has positive emissions reduction in equilibrium; however, emissions reductions of the private firm could be positive or zero. Under certain conditions, the optimal pollution tax is positive; otherwise, the tax reverts to a subsidy. Comparing mixed and private duopolies, privatisation leads to reductions in R&D and output, but to an increase in overall emissions, so privatisation tends to make the environment worse.  相似文献

We examine the relationship between environmental regulations and innovation, using data from UK manufacturing industry during 2000-2006. We estimate a dynamic model of innovation behaviour, and explicitly account for the likely endogeneity of our measure of the stringency of environmental regulations (pollution abatement costs). Our results indicate that while on the one hand environmental R&D and investment in environmental capital are stimulated by greater pollution abatement pressures, on the other hand there is not a positive impact of environmental regulation on total R&D or total capital accumulation. We find some evidence that this is because more stringent environmental regulations directly lower the optimal expenditure on non-environmental innovations. In addition, we find that environmental R&D may crowd out non-environmental R&D, although there is no evidence that environmental capital crowds out non-environmental capital.  相似文献

This study focuses on how the business type and technological learning mode, which a high-tech firm chooses based on its core competence, influence the firm's R&D strategies, which in turn affect firm performance. This study also explores how the interaction between a firm's business type and industry value chain stage affects the relationship between R&D investments and operating performance. We suggest that the linkage of R&D investments and operating performance will increase gradually, when firms move from contract manufacturing to own brand business. R&D investments can contribute more to performance when firms adopt the hybrid business type. Furthermore, R&D investments generate more significant benefits for the own brand companies than the contract manufacturers at the same stage of the industry value chain. R&D investments of the downstream contract manufacturers have a negative impact on firm performance. Regardless of business type, firms in the upstream (midstream) stage of the industry value chain outperform downstream stage firms in deriving benefits from R&D activities. Finally, the lagged effects of R&D investments on operating performance are affected by the interaction between business type and industry value chain.  相似文献

When there is multiplicatively separable demand and firms compete in the price dimension, there is no room for strategic use of R&D by firms. Under a different demand situation, strategic use of R&D by firms competing in the price dimension reduces R&D spending, reduces output, increases price, and increases profits of each firm.  相似文献

This paper studies vertical R&D spillovers between upstream and downstream firms. The model incorporates two vertically related industries, with horizontal spillovers within each industry and vertical spillovers between the two industries. Four types of R&D cooperation are studied: no cooperation, horizontal cooperation, vertical cooperation, and simultaneous horizontal and vertical cooperation. Vertical spillovers always increase R&D and welfare, while horizontal spillovers may increase or decrease them. The comparison of cooperative settings in terms of R&D shows that no setting uniformly dominates the others. Which type of cooperation yields more R&D depends on horizontal and vertical spillovers, and market structure. The ranking of cooperative structures hinges on the signs and magnitudes of three "competitive externalities" (vertical, horizontal, and diagonal) which capture the effect of the R&D of a firm on the profits of other firms. One of the basic results of the strategic investment literature is that cooperation between competitors decreases R&D when horizontal spillovers are low; the model shows that this result does not necessarily hold when vertical spillovers are sufficiently high, and/or when horizontal cooperation is combined with vertical cooperation.  相似文献

This paper examines whether stringent environmental regulations induce more R&D and promote further productivity in Taiwan. Using an industry-level panel dataset for the 1997–2003 period, empirical results show that pollution abatement fees, a proxy for environmental regulations, is positively related to R&D expenditure, implying that stronger environment protection induces more R&D. On the other hand, pollution abatement capital expenditures do not have a statistically significant influence on R&D. Further evaluation of the influence of induced R&D by environment regulations on industrial productivity shows a significant positive association between them. This finding supports the Porter hypothesis that more stringent environmental regulations may enhance rather than lower industrial competitiveness.  相似文献

We consider a differential game of R&D competition and explore the impact of rivalry on the firms' investment behavior over time. Using closed-loop strategies and hence allowing for strategic interactions among rival firms we show that R&D spending by the individual competitor is increased due to competition in the race for priority. This leads us to argue that competitive encounters enhance R&D activities at the same time as increasing efficiency in the race for a technological breakthrough.  相似文献

Environmental Research Joint Ventures under Emission Taxes   总被引:1,自引:0,他引:1  
The effect of environmentalpolicy depends crucially on the strategicbehavior of firms. Firms can undertakepollution abatement innovation cooperativelythrough environmental R&D joint ventures(RJVs). Environmental RJVs have not onlyenvironmental but also economic impacts. Threetypes of environmental RJV are discussed inthis paper: R&D cartelization in which firmschoose R&D efforts to maximize the jointprofit, RJV competition in which firms sharethe R&D fruits to maximize their own profits,and RJV cartelization in which firms share R&Dfruits and maximize the joint profit. An R&Dcartelization minimizes output quantities,maximizes the total emission, and minimizes thesocial surplus. An RJV cartelization with asufficiently high spillover coefficientmaximizes R&D efforts, minimizes the totalemission, and maximizes the social surplus.  相似文献

This paper examines how strategic alliances to create and use standards affect economic growth and development. The explanation of the link from standards to economic growth and development is through the effects of standards on the incentives to perform industrial research and development (R&D). We examine product standards, metrology traceable to national and international standards, and regulatory standards to address negative externalities. The paper develops a theoretical explanation for the link from standards to growth, survey/interview-guides to gather information from industrial R&D experts about the explanation, and case-study evidence about the explanation. We discuss the standard-setting process and explain that it entails strategic alliances among firms and with government involvement. Case studies of R&D projects in firms and in a national laboratory support the belief that standards implemented via strategic alliances leverage economic growth and development.  相似文献

The loss of employment is an essential issue that looms large in policy debates on pollution control. This paper estimates the impact of pollution reduction on labor demand in China’s manufacturing sector in the period 2001–2007. We conduct this research by using a sample with unbalanced panel data matched from two unique datasets of environmental statistics and an industrial economic database. Using the environmental performance of peer firms as the instrumental variable, our overall results show that improvements in environmental performance through reductions in \( SO _2\) emissions and COD emissions led to a statistically significant reduction in employment. On average, a 1% reduction in \( SO _2\) (COD) emissions causes a reduction in labor demand of approximately 0.018–0.019% (0.012–0.013%). We complement existing studies by carefully examining the impacts of firms’ different abatement strategies on labor demand. We find that pollution reduction through pollution prevention has substitutive effects on employment and that pollution reduction through pollution control at the end of the production process may require additional workers and thus has positive but not significant effects on labor demand. Finally, pollution control has heterogeneous effects on labor demand by different types of polluting firms (e.g., ownership, region, and industry).  相似文献

This paper analyzes differences in firms’ responsiveness to PROPER, Indonesia’s public disclosure program for industrial pollution control. The overall effectiveness of this program at achieving emissions reductions and its low regulatory costs have earned it a good reputation around the world. PROPER had no deterrents or incentives other than those that arose indirectly from publicly disclosing information about the environmental performances of firms. We analyzed plant-level data to relate short- and longer-term environmental responses to facility characteristics. The results revealed that foreign-owned firms were consistently more likely to respond to the environmental rating scheme, compared to private domestic firms. This is a clear and important insight with consequences for a number of issues, such as understanding the pollution haven debate. Also, firms located in densely populated regions, particularly in Java, responded more positively to the public disclosure of PROPER ratings. The main observed effect was however given by the initial level of environmental performance of firms. Those firms that had bad environmental performance records felt pressure to improve, but if the initial abatement steps had already been taken, the incentives to improve further appeared to diminish.  相似文献

This paper investigates the link between trade and environment by exploring the effects of green tariffs on innovation, location of production and the environment. It shows that tariffs levied on polluting goods could result in less world pollution than global harmonization of environmental standards by inducing more pollution-abatement R&D effort and generating lower unit emissions from production. Specifically, green tariffs reduce pollution by (1) shifting production to the region where environmental standards are respected, (2) inducing the firm in the clean country to engage in more abatement R&D by granting it a higher market power/share in its home market, (3) instigating green R&D investment by deterring delocation. When these outweigh the R&D-creating effect of environmental harmonization in the dirty country, green tariffs bring about a cleaner environment.  相似文献

Technological innovation through R&D is a critical element in enhancing and fostering firm performance. In particular, measurement of R&D efficiency throughout the innovation and commercialisation stages is important. However, almost of R&D efficiency-related studies assumed that R&D is a single stage. This study aims at analysing relative efficiency scores throughout the stages of the R&D process using a two-stage data envelopment analysis (DEA) model with a sample of 1039 Korean manufacturing firms. Based on our preliminary results, this study was extended by comparing subsample groups categorised by firm size and industry type. The key findings include: (1) firms show imbalanced R&D efficiency throughout the two stages and (2) R&D efficiency is different by firm size and industry type. The empirical results and findings may assist policy- and decision-makers to enhance R&D efficiency at the firm level. Moreover, introduction of the two-stage DEA model and comparative analysis methods to firm-level data contributes to scholars.  相似文献
