Revisiting the Porter hypothesis: an empirical analysis of Green innovation for the Netherlands

ABSTRACT

Almost all empirical research that has attempted to assess the validity of the Porter hypothesis (PH) has started from reduced-form models, for example, single-equation models for estimating the contribution of environmental regulation to productivity. This paper follows a structural approach that allows testing what is known in the literature as the ‘weak’ and the ‘strong’ version of the PH. Our ‘Green Innovation’ model includes three types of eco-investments to explain differences in the incidence of two types of eco-innovation, which are allowed to affect labor productivity. We allow for complementarity between the two types of eco-innovations. Using a comprehensive panel of Dutch manufacturing firm-level data we estimate the relative importance of environmental regulations on eco-investment and eco-innovations. The results of our analysis show a strong corroboration of the weak and a nuanced corroboration of the strong version of the PH.     

Environmental regulation and firm location choice in China

How may environmental regulation affect firm location choice? While this question has generated great research interest from high-standard, industrial economies, in this article we turn the spotlight to low-standard, developing countries and use China’s Census of Manufactures data during 2003–2008 to explore how firms with different ownership, during different policy regimes as well as from different industries may respond to environmental regulations in different ways. Results show environmental stringency has a positive effect on state-owned enterprises’ location choice during 2003–2005, but the effect becomes insignificant during 2006–2008. Private-owned enterprises, foreign-owned enterprises and collective-owned enterprises are more likely to enter areas with less stringent environmental regulations during 2003–2005. However, this pattern is reversed for the period of 2006–2008. Furthermore, the above relationships are more pronounced for firms in polluting industries.     

The nonlinear effects of firm size on innovation: an empirical investigation

ABSTRACT

In conventional studies, large firms tend to emphasize more on process innovation than product innovation. This paper explores factors that could indicate a distinct pattern of firms’ innovation-size relationship: threshold size that implies a positive effect of firm size on the probability of product innovation success; cannibalization effect that creates incentives for large firms to favor product innovations; and financial constraints that have differential effects given different firm sizes. A hypothesis about a non-monotonic relationship between the proportion of product innovation and firm size is tested with nonlinear and dynamic econometric models. For the large firms, empirical evidence shows product innovations result in an overall larger share of new products in total sales, relative to existing products in which process innovations are rooted.     

The environmental Porter hypothesis: theory,evidence, and a model of timing of adoption

The Porter hypothesis postulates that the costs of compliance with environmental standards may be offset by adoption of innovations they trigger. We model this hypothesis using a game of timing of technology adoption. We will show that times of adoption will be earlier if the non-adoption tax is higher. The environmental tax will turn the preemption game with low profits into a game with credible precommitment generating higher profits (pro-Porter). If there is a precommitment game without environmental taxes, the introduction of a tax will lead to lower profits (anti-Porter). An evaluation of the empirical literature indicates that the Porter hypothesis will hold even for profit-maximizing firms under multiple market imperfections such as imperfect competition, X-inefficiency, and agency costs. These are more likely to be present in sectors with large firms. In many case studies that we have evaluated, though, we detected an element of explicit or implicit subsidies for environmentally friendly behaviour, which is in line with Pigovian policies.     

Decomposing the contribution of firm innovation to aggregate productivity growth: the case of Chinese manufacturing industry

This article proposes a generalized productivity decomposition approach to evaluate the contribution of firm innovation to aggregate productivity growth (APG) of China’s manufacturing industry. Results indicate that APG is mainly driven by firm-level productivity improvements, while across-firm resource misallocations lead to sizable productivity losses. The weak contribution of firm innovation to APG is found to be mainly caused by resource misallocations within innovating firms. The results suggest that firm innovation has not yet taken a dominant driving force for APG.     

The firm in early Modern China

The Chinese shareholding entity had a long history supported by cultural and legal practices pre-dating the introduction of European business forms in China. In the absence of codified or systematic precedent-based private law, a culture in which contract was deeply embedded in daily practice and the state enforced private agreements sustained a growing commercial sector. Kinship practices were adapted to the needs of a merchant community seeking ways to pool capital and sustain firm longevity. These institutional developments help to explain Chinese adaptability to Western practices and the paradoxical persistence of Chinese practices after the promulgation of a Western-style company law.     

Employment growth and innovation at the firm level

We analyze the influence of innovation on growth rates of employment in 859 Dutch manufacturing firms over the period 1983–1988. Whereas the (growth of the) R&D intensity of firms has a slightly negative impact on employment, we find that firms with a high share of product-related R&D (as a proxi of R&D related to industrial activities in an early stage of the life cycle) experienced an above average growth of employment. The same holds for firms which directed their R&D towards information technology. Smaller firms have, ceteris paribus, substantially higher growth rates of employment than their larger counterparts. Against our expectations, R&D cooperation has no significant impact on employment growth. The same holds for activities in the fields of biotechnology and new materials.     

Board monitoring,firm risk,and external regulation

We examine the relationship between board monitoring and firm characteristics using a broad sample of firms over the 8 year period from 1996 to 2003. We find that board independence and monitoring is negatively related to firm risk in the absence of external regulation. In addition, we find that external regulatory and political pressures affect the level of board monitoring, especially after the increased focus on board composition by the stock exchanges beginning in 1999 and the passage of the 2002 Sarbanes–Oxley Act. We find that the sensitivity of the negative relationship between board monitoring and firm risk decreases in the post 1999 period suggesting that firms have increased board monitoring in response to external regulations. We also find that these external regulations have had an asymmetrical impact on high-risk firm. In our empirical analysis we also control for other factors that affect board monitoring and find that firms in which the CEO has longer tenure and greater equity ownership have less board monitoring activity and that there is a negative relationship between the level of board monitoring and the level of shareholder rights.      

Voluntary development of environmental management systems: motivations and regulatory implications

Encouraging firms to develop voluntarily more comprehensive environmental management systems (EMSs) is touted as a policy tool to augment mandatory environmental regulations. Using a unique dataset of environmental management practices of Japanese manufacturers and controlling for self-selection bias in survey responses, we find that proxies for regulatory pressures and consumer pressures are the most important factors that motivate firms toward more comprehensive EMSs. Despite the oft-claimed “voluntary” nature of EMS development, our results show that the government may have a role to play in both directly and indirectly affecting EMS development by firms.      

The merits of non-tradable quotas as a domestic policy instrument to prevent firm closure

Many countries fear that adopting a domestic tradable quota system for greenhouse gases that requires all emitters to pay for their quotas may lead to closures of emissions-intensive industrial companies. The starting point of this paper is that a government, to avoid firm closure, has opted to allocate quotas free of charge to emission-intensive industries. The aim of this paper is to explore to what extent making the free quotas tradable or non-tradable will affect investment in new abatement technology and firm closure. The conclusion is that the expectations about future product prices and the number of quotas distributed free of charge are crucial for the difference in the properties of tradable and non-tradable quotas.     

A Schumpeterian model of investment and innovation with labor market regulation

Theoretical and empirical models provide ambiguous responses on the relationship between labor market regulation, innovation and investment. On the one hand, labor market regulation increases firms' adjustment costs and, ceteris paribus, decreases investment. But, on the other, it also stimulates firms to invest, innovate, increase productivity and profit in the long run. In this paper we present an endogenous growth model that describes the role of these opposite forces, and why a stricter labor market regulation may positively affect innovation and investment in the long run. Most of the theoretical and empirical results hold for Italy, Germany, France, and Spain.     

The impact of environmental regulation on Chinese spatial development

We examine the relationship between environmental regulation and spatial development in China. Exploiting changes in national pollution standards for three industries, ammonia, paper and cement, we measure the impact of environmental regulation on industry productivity. Our results suggest that national pollution standards do not affect industry productivity, but they reallocate productivity spatially. We show that regulated industries located in developing cities increase their productivity compared to similar industries in other cities. This means that environmental regulation affects the spatial distribution of technology in China and might influence long‐term spatial development by reducing geographical disparities.     

“污染避难所”假说在中国的实证检验

The effects of corporate environmental disclosure on environmental innovation from stakeholder perspectives

Based on legitimacy theory and resource dependence theory, using 111 listed companies among China’s typically high pollution-emitting listed corporations, research into the effects of environmental disclosure on environmental innovation is undertaken. From the perspective of stakeholders, we analyse the moderating effects of different proportions of institutional investor holdings and types of enterprises on the relationship between environmental disclosure and environmental innovation. The results indicate that corporate environmental disclosure has a positive role in promoting environmental innovation; the proportion of institutional investor holdings has a positive moderating effect between environmental disclosure and environmental innovation. However, there is no significant difference between state-owned enterprises and private enterprises in terms of the effect of the environmental disclosure on environmental innovation, which possibly arises because both types of enterprises make full use of their own advantages to instigate environmental innovation through environmental disclosure. The conclusions may help enterprise decision-makers implementing environmental innovation and government policy makers formulating scientific policies to promote the clean production in enterprises.     

Technical efficiency under alternative environmental regulatory regimes: The case of Dutch horticulture

We consider the performance of small and medium sized enterprises in Dutch horticulture under different environmental policy regimes across time. We address the question whether technical performance differs under these alternative regulatory regimes to test Porter's hypothesis that stricter environmental regulation reduces technical inefficiency. For this purpose, we use a stochastic production frontier framework allowing for inclusion of policy variables to measure the effect of alternative environmental policy regimes on firms' performance. The main result is that stricter environmental policy regimes have indeed reduced technical inefficiencies in Dutch horticulture. The estimation results indicate amongst others that the 1997 agreement on energy, nutrient and pesticides use enhances technical efficiency. Firms under the strict environmental policy regime are found to be more technically efficient than those under a lax regime, thereby supporting the claims by Porter and Van der Linde (Porter, M., Van der Linde, C., 1995. Green and Competitive: Ending the stalemate. Harvard Business Review 73, pp. 120-137) concerning Dutch horticulture.     

国外关于政府环境管制问题的研究走向

20世纪70年代以来,国外管制的实践与理论研究的重心开始从经济性管制转移到社会性管制上来。随着经济的增长和收入水平的提高,人们对生活和工作的质量提出了更高的标准和要求,从而,促使政府不得不重视环境质量管制。     

Regulation and innovation: Examining outcomes in Chinese pollution control policy areas

In this paper, we examine how two regionally implemented environmental initiatives in China have impacted the innovation ability of Chinese-listed firms. The regional implementation of these policies, with non-policy regions serving as controls, offers researchers the perfect conditions for a natural experiment. Using research and development (R&D) expenditures and patents as a proxy for innovativeness, we compare the record of innovation of firms inside the policy zones with firms outside the policy zones. We use a Difference-In-Difference-In-Differences (DIDID) method to eliminate endogeneity and take the quality of the patents into account by incorporating sub-items. Results show only one of the regulations had a positive effect and that low quality patents account for most of the innovation. We conclude that reasonably designed environmental regulations, when implemented regionally in competitive industries, do improve Chinese firms' innovation ability in line with the Porter Hypothesis. The results help us derive some useful policy implications regarding innovation.

The relationship between pollution abatement costs and environmental regulation: Evidence from the Chinese industrial sector

Since the 2000s, China has been trying to strengthen emission controls in response to increasing pollution problems. However, strict implementation of emission controls generates pollution abatement costs. Using regional data for 29 provinces in the Chinese industrial sector from 1995 to 2010, this study estimated the pollution abatement costs for each province through the measurement of environmental efficiency, by applying a directional distance function approach. Moreover, using panel data analysis, this study clarified whether there is a nonlinear relationship between pollution abatement costs and environmental regulations. The empirical results are as follows. The study confirmed that the burden of abatement costs tended not only to occur in the central and western regions but also to increase in the eastern region. Moreover, the nonlinear relationship is inverted U‐shaped; thus, pollution abatement costs increase, as a negative effect of environmental regulations, until a certain inflection point, after which they decrease.
