Green Inquiry Letter and Corporate Green Innovation

As a form of non-punitive regulatory policy, the inquiry letter has garnered significant attention from academic circles. However, its impact on corporate green innovation has not been fully explored. This study aims to address this gap by examining the influence of green inquiry letters (hereinafter referred to as "green inquiry letters") on corporate green innovation activities based on data from listed companies spanning 2015 to 2022. The findings indicate that green inquiry letters issued by the exchange can effectively promote the green innovation of enterprises, and this conclusion holds true even after conducting a series of robustness tests. Furthermore, in regions with higher levels of pollution and increased public concern, the impact of green inquiry letters is particularly pronounced. Mechanism analysis reveals that green inquiry letters lead to a significant increase in both pollution charges and negative news coverage for enterprises, thereby facilitating their transition towards environmentally-friendly practices. Overall, it is evident that green inquiry letters stimulate green innovation by heightening regulatory pressure and non-compliance costs faced by companies. This underscores the crucial role played by these letters in enterprise supervision and provides valuable insights for enhancing securities market regulation mechanisms.

The Impact of Environmental Regulation on Technological Innovation of Enterprises: Based on Empirical Evidences of the Implementation of Pollution Charges in China

Abstract Environmental protection is closely related to high-quality economic developments. Based on the matching of micro-databases from 2000 to 2008, this study used the “Regulations on the Collection and Use of Pollution Fees” policy implemented in China in 2003 as the exogenous impact to construct the intensity Difference in Differences model in order to investigate the effects of pollutant discharge fee on technological innovation of enterprises and the underlying mechanisms. The results showed that governmental environmental regulations significantly improved the level of technological innovation of enterprises, and the conclusion was still valid after a series of robustness tests. The results of the parallel trend verified the rationality of the differential setting and the dynamic effects showed that the pollutant discharge fees had a continuous promoting effect on the technological innovation of enterprises. The results of the placebo tests rejected the original hypothesis of the mistaken model. The mechanism verifications revealed that the strengthening of environmental regulation by the government acted on the innovation level of enterprises through the two mechanisms, i.e., the promotion of enterprises’ fixed asset investments and government subsidies, and finally improved the enterprises’ technological innovation levels.

The health Loss Distribution of Coal-fired Power Plants and the relationship to Air Pollution Charges

In this study, the regional health loss due to the air pollution of a coal-fired power plant is analyzed by using the atmospheric dispersion model. AERMOD was used to simulate the increment concentration map of point source emission, and the GIS geographic information system was used to displace the distribution of air pollution concentration and regional health loss in grid receptors. The data of the continuous automatic monitoring facilities and the source of pollution sources were analyzed. Moreover, the effects of emissions, seasons, population, and distance on the simulated concentration were evaluated. The various influencing factors of air pollution concentration were evaluated.the R2 value of the empty product prediction map in summer has a better correlation with the concentration from monitor station, between 0.38 and 0.83, and the sulphur dioxide correlation has the best R2 value of 0.83. AERMOD was used to combined with pollutant emissions, weather, and terrain data, to simulate the distribution of rising concentration values due to coal-fired power plant emissions within the research area, and the study used the simulated rising concentration values to calculate the health loss. [1] The study used health loss of 25,647,291,161 NTD/year and medical loss of 319,153,198 NTD/year.

Pollution charges and firms’ energy efficiency: evidence from a quasi-natural experiment in China

ABSTRACT Pollution charges are an important way to improve energy efficiency. Using the relevant data of Chinese industrial firms from 2003 to 2010, we take China’s Pollution Levy Standard Reform (PLSR) implemented in 2007 as a quasi-natural experiment, and use the staggered difference-in-differences method to empirically test the impact of pollution charges on green total factor energy efficiency (GTFEE) of firms. We find that pollution charges significantly increase firms’ GTFEE. This result is still valid under a series of robustness tests. The potential mechanism is that although pollution charges increase the cost of firms, they also promote technological innovation of firms, and ultimately in the overall effect pollution charges improve the GTFEE of firms. In addition, the positive effect of pollution charges on GTFEE is greater for non-state owned enterprises, non-exporting enterprises and enterprises in heavily polluting industries.

Development of environmental costs in mining company after implementation of innovation - cyclone separator

This article summarizes the scientific discussion on the environmental costs of mining companies. Reducing environmental pollution in mining companies is focused on three strategies. The raw material intensity decrease is the first strategy. The second strategy is orientated to changes in the production of environmental products. The third strategy is directed at the consumption of products and liquidation after their lifetime. The priority goal of this paper was to demonstrate the development of environmental costs after the implementation of cyclone separators focusing on the expenses in the field of water management. Methods of research were focused on using index analysis and structure analysis. Base index and chain index were used in the analysis of the index. The object of the article was the mining company focused on mining limestone in Slovakia. The priority problem is the dust of the mining process. The research brings new solving a cyclone separator in the mining process for reducing dust. The goal "Operational Program Environment" is to invest in the water sector, creating mining companies' problems. Mining companies use water resources for their mining activities. The results of the study show decreasing in environmental costs. Water and sewerage fees eliminate by 11.1 %, air pollution charges by 11.5 %, disposal fees by about 5.2 %, and towing the sump by 1.5 %. The purpose of the mining company is to address environmental costs as a priority issue related to environmental protection. Competitive advantage for the mining industry introduces efficient and acceptable solutions - innovations.

Governance matters: Urban expansion, environmental regulation, and PM2.5 pollution

Increasing PM2.5 pollution in urban expansion threatens citizens' health. Environmental regulation has proven to be an effective tool to directly combat PM2.5 pollution. However, whether it can moderate the impacts of urban expansion on PM2.5 pollution, in the context of rapid urbanization, is an interesting and unexplored topic. Therefore, this paper constructs a Drivers-Governance-Impacts framework and explores in depth the interactions among urban expansion, environmental regulation, and PM2.5 pollution. Based on 2005–2018 sample data from the Yangtze River Delta region, the estimation results of the Spatial Durbin model imply that (1) urban expansion has an inverse U-shaped association with PM2.5 pollution. The positive correlation may reverse when the ratio of urban built-up land area hits 0.21. (2) Of the three environmental regulations, investment in pollution control has little impact on PM2.5 pollution. Pollution charges and public attention exhibit a U-shaped and inverted U-shaped relationship with PM2.5 pollution, respectively. (3) In terms of moderating effects, pollution charges can exacerbate PM2.5 pollution from urban expansion, while public attention can inhibit it through its monitoring role. Therefore, we suggest that cities adopt differentiated strategies of urban expansion and environmental protection according to their urbanization levels. Meanwhile, appropriate formal regulation and strong informal regulation will help improve air quality.

Research on the Policy Analysis of Sustainable Energy Based on Policy Knowledge Graph Technology—A Case Study in China

Nowadays, geopolitical, extreme weather and other emergencies have exacerbated the global energy crisis, and thus, have increased the urgency of the world’s transition to sustainable energy. Sustainable energy policies play an important role in the process of sustainable energy transformation. The research on sustainable energy policy is mainly carried out through conventional qualitative and quantitative methods, in which bibliometrics and meta-analysis methods are paid attention to; however, the mining and analysis of the semantics of the relationships between policies are ignored. This paper uses knowledge graph technology to build a knowledge graph of China’s sustainable energy policy by using 10,815 open official documents of sustainable energy policy issued by China from 1981 to 2022. It forms the relevant policy archive storage and details related organizations. The legal source can be traced through the graph database, where the powerful synergy can be seen, and the policy focus can be monitored. In terms of structural data, this paper uses graph algorithms to identify key policy nodes at different stages, to identify the key government departments for policy issuance and cluster policy issuance departments, and it investigates China’s policy evolution in the issue of sustainable energy policies, the evolution of policy issuance departments, and the power co-evolution process between policy issuance departments. The research found that: (1) China’s sustainable energy policy was initiated in environmental protection, and the relevant policies on collecting pollution charges has continued to play an important policy node. Additionally, the three versions of the Environmental Protection Law of the People’s Republic of China have successively become the main legal source of other sustainable energy transformation policies. (2) The prominent feature of China’s sustainable energy policy transformation has involved transforming the process where the issuance of policies came from a single department to the joint issuance of documents by multiple departments. The joint exercise of government functions and powers by multiple departments jointly promotes sustainable energy policies’ implementation and play. (3) In the future, when formulating sustainable energy policies, the Chinese government should focus on the strategic and systematic aspects of the policies, so that the sustainable energy policies can meet both short-term and long-term development goals. At the same time, the synergy of various policies and measures should be fully played in implementing sustainable energy policies. The establishment of the policy knowledge graph based on publicly-open official documents can facilitate the analysis and visualization of sustainable energy policies, providing new ideas for policy research. This paper introduces the knowledge graph, graph machine learning algorithms and big data technology, which can deepen the depth and breadth of people’s research on sustainable energy policy. This study will help the public policy formulation work in the future and has a positive reference value for the evaluation of the implementation effect of policy objectives.

New media environment, environmental regulation and corporate green technology innovation:Evidence from China

Understanding the impact and mechanisms between new media environment, environmental regulation and corporate green technology innovation are crucial to achieve environmentally inclusive growth of sustainable development goals. Based on the sample of Chinese A-share listed companies in the heavily polluting industries for the period 2010–2020, this paper investigates the impact of the new media environment and environmental regulation on corporate green technology innovation. The empirical results indicate that (i) the new media environment can motivate heavily polluting enterprises to meet stakeholder demands and significantly improve their corporate green technology innovation; (ii) heterogeneous environmental regulatory instruments (pollution charges and environmental protection subsidies) can jointly improve the green technology innovation of corporations through pushback and compensation effects; and (iii) effective environmental regulation tools can strengthen the stakeholder relationship between the government and enterprises, enhance the resource preparation and dynamic capabilities of heavily polluting enterprises to respond to public opinion crises, and thereby positively moderate the promotion of new media environments on corporate green technological innovation. Our findings help identify new drivers of corporate green technology innovation and confirm the combined effects of the new media environment and environmental regulation in stimulating corporate green behavior, which can facilitate the construction of ecological civilization.

Did the pollution charge system promote or inhibit innovation? Evidence from Chinese micro-enterprises

Studying the impact of the former Pollution Charge System (PCS) on enterprise innovation will provide a reference for China to improving the current environmental protection tax system (EPTS). Based on innovation panel data and the sewage charges applied to polluting enterprises in China, this paper empirically analyzes the impact of the PCS on enterprise innovation. The results show that the PCS significantly inhibits the patent output of enterprises. The study analyzes heterogeneity in these findings in three respects: enterprise scale, enterprise ownership, and regional development level. The results are as follows: 1) The PCS has a greater inhibitory effect on smaller enterprises' innovation than on larger enterprises; 2) The inhibitory effect on non-state-owned enterprises' innovation is greater than on state-owned enterprises; 3) The inhibitory effect is greater for enterprises located in western regions of China. We also use a difference-in-differences strategy to address endogeneity concerns. The mediation analysis finds that the mechanism of the PCS affecting innovation is to reduce enterprise cash flow and R&D expenditure.

Influence Mechanism of Different Environmental Regulations on Carbon Emission Efficiency.

The rational use of environmental regulation tools has become an important means by which to improve the efficiency of carbon emissions. Different types of environmental regulations and their combinations have different impacts on carbon emission efficiency. In order to determine the environmental regulation configurations that may achieve high carbon emission efficiency or lead to low carbon emission efficiency, we constructed an analytical framework of connections between environmental regulation configurations and carbon emission efficiency. Moreover, 30 Chinese provinces from the period covering 2016 to 2019 were selected as research cases. In addition, the super slacks-based measure of efficiency (SE-SBM) model was applied to evaluate carbon emission efficiency. Finally, the fuzzy-set qualitative comparative analysis (fsQCA) method was employed to analyze the impact of different environmental regulation configurations on carbon emission efficiency. The results showed that the carbon emission efficiency of various regions of China is generally low (with most regions not having reached an effective level) and that there are large regional differences. We found that there are four environmental regulation configurations that can achieve high carbon emission efficiency and two environmental regulation configurations that lead to low carbon emission efficiency. Based on these configurations, we draw three conclusions: (1) There are three paths to achieving high carbon emission efficiency: one that values command-and-control environmental regulation but disfavors market-incentive environmental regulation, another that combines command-and-control environmental regulation with market-incentive environmental regulation, and a third that couples command-and-control environmental regulation with voluntary environmental regulation. (2) Two paths that may lead to low carbon emission efficiency were established: excessive penalties and the lack of specific measures. (3) In some conditions, environmental governance investment and fiscal expenditure could be substituted for each other; environmental protection administrative penalties and pollution charges are synchronized; environmental governance investment in the promotion of carbon emission efficiency is indispensable. Policies and suggestions on how the government can use environmental regulation tools to improve carbon emission efficiency are proposed from a general coordinative perspective in the final section of this paper.

The relationship between policy adjustment of SO2 emissions charge standard and the growth of green total factor productivity—Evidence from China

Evaluating the impact of environmental pollution charge system reform is necessary to help formulate a suitable policy to achieve a goal of emission control. The paper examines the relationship between policy adjustment of SO2 emissions charge standard (PSC) and urban growth of green total factor productivity (GGTFP) using a natural experiment data of 280 cities in China. The results indicated that the improvement of SO2 emissions charge standard can reduce emission and promote the GGTFP. Furthermore, it reveals an “N” relationship between the policy time period and the GGTFP, and an “Inverted-U” relationship between policy intensity and the GGTFP. The results imply that there is some policy room for policy makers to set a shadow price of pollution charge to maximize policy effect, and it is also important to consider the policy effect in the implementation time and intensity to maximize the policy effect and resource efficiency for the GGTFP and sustainable development.

Can driving-restriction policies alleviate traffic congestion? A case study in Beijing, China

With ongoing urbanization, traffic congestion and the air pollution it induces are worsening. Using a system dynamics (SD) approach, this study constructed a driving-restriction policy model to explore the effects of different stages of policy implementation on variables such as traffic congestion, emissions, and parking demand. Medium- and long-term dynamic simulation showed that the effect of the policy was obvious in the initial stage but gradually weakened in the medium term, leading to a “fading” effect on traffic-congestion alleviation; a “rebound” effect was even observed at the end of the simulation. Thus, the policy will not effectively reduce traffic congestion in the long term and will induce a new demand for car purchases, resulting in paradoxical effects, which will aggravate parking demand, congestion, and pollution. Yet, it was also found that introducing penalty policies and an air pollution charging fee could weaken the paradoxical effects and compensate for some defects of the policy. Such strategies could help reduce emissions, traffic congestion, parking demand, the number of illegal trips, and the overall number of vehicle trips. These findings can provide not only a theoretical basis for further research but also practical guidance for policy improvement.Graphical abstract

Corporate Environmental Governance Strategies Under the Dual Supervision of the Government and the Public

External regulatory and normative pressures from both the Chinese central environmental protection inspection (CEPI) program and public participation can act together to influence corporate environmental governance behavior. This research uses the multiperiod Difference-In-Differences method to test the compound impact of CEPI and public participation on corporate environmental governance strategies and investigate the underlying influence mechanisms. The results show that CEPI and public participation have a positive compound effect on the corporate “source-control” strategy. A reasonable reduction in pollution charges and increased environmental subsidies are essential to stimulate the green innovation potential of heavily polluting firms. Our research helps clarify the game relationship between the central and the local governments and analyzes how the relationship between the government, the public, and corporates affects environmental governance, thereby advancing principal-agent theory and expanding the current research on institutional pressures and corporate environmental governance.

Social Responsibility and Urban Consolidation Centres in Sustainable Freight Transport Markets

This paper investigates the impact of Corporate Social Responsibility (CSR) strategies adopted by urban consolidation centres on the competition between logistics service providers. Taking into consideration pollution charges issued by city councils to reduce CO2 emissions in freight distribution, we study a Hotelling-like market setting where logistics providers could voluntarily outsource last mile deliveries to platforms endowed with eco-friendly vehicles. We considered the intensity of the competition, which is captured by switching costs and we theoretically find that in more contestable markets, the interplay between environmental policies and CSR strategies—intended as consumers-oriented pricing schemes—is more likely to enhance the demand by providers for consolidation centres’ deliveries. Conversely, when the competition is weak, i.e., the providers have a relatively strong market power, platforms’ services are less attractive and more relevant CSR pricing strategies are needed to spread out greener freight deliveries and make city logistics environmentally sustainable.

Exploiting Olive Mill Wastewater via Thermal Conversion of the Organic Matter into Gaseous Biofuel—A Case Study

Olive oil is one excellence of the Italian food industry: around 300 kt yr−1 are produced, creating roughly the same amount of olive mill wastewater (OMW) to be disposed of. The present work describes a process to exploit OMW by converting its organic compounds to valuable gaseous biofuel. A sample OMW was characterized (COD, TOC, solids, and polyphenols) and submitted to membrane filtration tests to concentrate the organic compounds. Based on the results of the experiments, a treatment process was outlined: the retentate streams from microfiltration and ultrafiltration steps were fed to a cracking and a steam reforming reactor, respectively; the obtained syngas streams were then mixed and sent to a methanation reactor. The process was simulated with Aspen Plus (AspenTech©) software, assessing operating conditions and streams compositions: the final biofuel is around 81 mol.% methane, 4 mol.% hydrogen, and 11 mol.% carbon dioxide. The permeate stream cannot be directly disposed of, but both its amount and its polluting charge are greatly reduced. The heat needed by the process, mainly due to the endothermic reactions, can be obtained by burning an amount of olive pomaces, roughly corresponding to one-third of the amount left by olive treatments giving rise to the processed OMW feed.

Energy Conservation or Emission Reduction? The Effects of Different Types of Environmental Regulations on Enterprises’ Green Innovation Preference

Previous research on green innovation sought to comprehend the antecedents and outcomes of environmental regulations. However, how these antecedents translate into outcomes may vary depending on different types of environmental regulations, such as environmental subsidies and pollution charges. We propose and test the effects of different environmental regulations on enterprises’ green innovation preferences. Moreover, we analyze how ownership type moderates the observed effects. The fundamental results reveal that: (1) Environmental subsidies and pollution charges positively affect energy conservation innovation. (2) Environmental subsidies and pollution charges positively affect emission reduction innovation. (3) Pollution charges are not as effective as environmental subsidies in promoting energy conservation innovation. However, pollution charges have a greater implementation effect than environmental subsidies in encouraging emission reduction innovation. (4) The types of enterprise ownership only play a positive moderating role in the relationship between pollution charges and emission reduction innovation. Accordingly, this paper provides auxiliary decision-making for the government to motivate the energy conservation and emission reduction of enterprises.

Environmental information disclosure and green technology innovation: Empirical evidence from China

Environmental information disclosure is a dominant feature of good ecological environment construction, which reflects the emergence of social supervision. In this paper, we employ the Difference in Difference (DID) method, for 289 prefecture level cities in China that allows us to open up new empirical evidence of the effects on green technology innovation. The results indicate that disclosure of environmental information is more likely to promote green technologies, which is measured by green patent application. As substitute indicators, green patent of utility model and invention patent further confirm the result by robust test. To address the potential regional heterogeneity, we find eastern China might be the place where the above three green patent application have their most pronounced effects. Pollution Information Transparency Index (PITI) was designed to spur innovation, which also has been proved in our paper. Furthermore, green innovation environment, pollution charges and industrial structure have been identified as mediator variables, and foreign investment, government education and technology expenditure in terms of capital investment have been testified as moderator variables.

The Heterogeneous Relationship between Pollution Charges and Enterprise Green Technology Innovation, Based on the Data of Chinese Industrial Enterprises

Enterprises’ green technology innovation is critical to achieving the “win-win” of enterprise competitiveness and environmental protection. The impact of environmental regulation on green technology innovation by enterprises has been widely considered, but the conclusion has not yet been determined, and needs to be studied in detail. To this end, we studied the impact of pollution charge policy on different types of green technology innovation by industrial enterprises in China. We found that (1) the impact of pollution charges on most types of green technology innovation by enterprises has increased significantly over time; (2) the pollution charge policy has a certain inhibition effect on the end-of-pipe technology innovation, but can promote the process improvement of reducing industrial wastewater emissions; (3) there is a U-shaped relationship between the pollution charges and some green technological innovation (e.g., emission intensity of SO2, industrial wastewater emission intensity, and industrial wastewater removal intensity), which is dynamically adjusted over time; and (4) the larger the enterprise’s solid assets, the faster the asset depreciation will inhibit the enterprise from adopting the green process innovation strategy.

Can environmental tax bring strong porter effect? Evidence from Chinese listed companies.

Existing researches verify Porter hypothesis mainly through one of its core establishment paths, innovation compensation, but ignore the other one, first-mover advantages. This paper considers both these paths and further distinguishes environmental R&D and non-environmental R&D in empirical study. Based on the smooth transition principle of "charge to tax" in China, this paper, taking Chinese A-share listed companies that have disclosed environmental R&D from 2008 to 2017 as sample and predicting environmental tax by pollution charge, analyzes the relationship between environmental tax and firm performance and its transmission mechanism. First, our results show that environmental tax can improve firm performance, and this influence remains in long term. After introducing instrument variable (IV) to deal with endogeneity and conducting a series of robustness tests, we then find that the relationship between environmental tax and firm performance is a robust causality. Eventually, we apply mediating effect model to further confirm the two core paths of Porter hypothesis by manifesting that environmental tax can affect firm performance through both innovation compensation and first-mover advantages. Our contributions are revealing the micro mechanism of environmental tax on firm performance, providing evidence from China to support strong Porter hypothesis, and offering some key points regarding environmental tax reform and corporate green strategy.

Protecting Marine biodiversity is not only essential to the functioning of the earth's ecosystems, but also closely related to human well-being. Based on the indicators of Marine ecosystem health and species diversity damage in China's coastal provinces, this paper use panel regression model to analyze the relationship between economic growth and Marine biodiversity damage in China's coastal areas. The results showed that:(1) there is a significant linear relationship between the sub-health degree of Marine ecosystems and the economic growth in coastal areas. With the economic growth, the sub-health status of typical Marine ecosystems has a continuous upward trend. In addition, the implementation of pollution charge system and the establishment of Marine nature reserves are conducive to suppress the deterioration of Marine ecosystem. (2) There is an inverted U-shaped relationship between the damage of Marine species diversity and the economic growth of coastal areas. The turning point was 45,145 yuan per capita GDP. With economic growth, the damage of Marine species diversity increase first and then decrease. From the perspective of time trajectory, the inflection point of species diversity damage corresponds to the time stage from 2009 to 2010. From the perspective of spatial distribution, Hainan province, Guangxi Zhuang Autonomous Region and Hebei Province are still in the rising part of the curve, The economic growth level of Shandong, Liaoning, Shanghai, Zhejiang, Tianjin, Jiangsu, Guangdong and Fujian provinces has passed the inflection point value, those provinces are in the curve decline stage. The pollution charge system is beneficial to suppress the Marine species diversity damage, but the current industrial structure in coastal areas aggravate the Marine species diversity damage. According to the results of empirical analysis, we know that if the economic growth is based on the destruction of the ecological environment, it is bound to cause damage to biodiversity. Even though there is an inverted U-shaped relationship between Marine species diversity and economic growth in coastal areas, there is still no inflection point between economic growth and Marine ecosystem health, so the sub-health of Marine ecosystem may further lead to the loss of Marine biodiversity, forming a vicious circle. some suggestions are put forward to protect and manage Marine biodiversity:(1) we should strengthen biodiversity protection, broaden the ways of Marine biodiversity protection, and ensure the diversity of Marine biodiversity protection methods;(2) we should maintain a green and sustainable pattern of economic development and promote industrial restructuring and upgrading. meanwhile, we should guide the smart growth of coastal areas and prevent the occupation of coastal wetlands and large-scale reclamation of land due to blind pursuit of economic growth. 参考文献 相似文献 引证文献
