How R&D investment promotes green technology innovation in the context of digitalization?-An empirical analysis based on provincial panel data

Green technology innovation is an important driving force and source to promote my country’s high-quality development,and it is the core path to achieve sustainable development.This paper uses my country’s provincial panel data from 2016 to 2019 to study the impact mechanism of R&D investment on green technology innovation,and introduces the level of digitization,using the panel threshold model to discuss its role in the impact mechanism of R&D investment on green technology innovation.The study found that when the level of digitalization in a region is low,increasing R&D investment does not necessarily improve the ability of green technology innovation;when the level of digitalization is relatively high,R&D investment has a positive role in promoting green technology innovation.Therefore,it is necessary to improve policies to encourage enterprises to increase investment in research and development;at the same time,it is necessary to promote the coordinated development of digital foundation,digital investment,digital literacy,digital economy and digital application,and promote the deep integration of digitalization and green technology innovation.

Study on the efficiency and regional disparity of green technology innovation in China's industrial companies

This paper first constructed a system to evaluate the innovation efficiency of industrial companies within China's Mainland.Then,a principal component analysis(PCA) was performed to these indicators for dimensionality reduction,so as to figure out the technology innovation efficiency in these two phases,respectively.Finally,the overall efficiency of industrial companies in different regions was estimated and factorized via data envelopment analysis(DEA).The results showed that:(1)the efficiency of green technology innovation of industrial companies in China was relatively low as a whole,which mainly resulted from pure technical efficiency(PTE).Further,this huge gap continues to expand in these regions.And both PTE and scale efficiency(SE) in central and western regions leave much to be expected.(2)In the first phase of green technology development,when environmental factors were concerned,the efficiency was much lower than that without environmental considerations.Besides,the central and western regions were facing increasingly severe environmental problems,and there was a wide disparity in technology development efficiency among eastern,central,and western regions.(3)In the second phase of green technology commercialization,there were still more rooms for improvement in raising the efficiency of green technology innovation,and the efficiency in eastern,central,and western regions was ranked from highest to lowest.(4)Liaoning,Hebei,Heilongjiang,Xinjiang,Shanxi,Inner Mongolia,Yunnan,and Qinghai should focus on improving their technology;Jilin,Jiangxi,Anhui,and Guangxi should make their efforts to reduce resource redundancy;whereas Ningxia and Gansu should try to solve the above two issues.

Calculation of the influence of Green Technology Innovation to Eco-Industrial Management in China

The function of Green Technology Innovation （GTI） in the Eco-Industrial Management （ELM） appears more and more important, but the research on how much this function plays is scarce. The influence of Green Technology Innovation to the Eco-Industrial Management has gradually received the academic and the industrial attention. In this article an empirical research was attempted to inspect whether such influence exists and to what value. The study attempts to empirically explore the influencing degree of GTI on EIM in China based on the double logarithmic regression equation.

Phytoremediation:A Green Technology to Remove Environmental Pollutants

Land, surface waters, and ground water worldwide, are increasingly affected by contaminations from industrial, research experiments, military, and agricultural activities either due to ignorance, lack of vision, carelessness, or high cost of waste disposal and treatment. The rapid build-up of toxic pollutants (metals, radionuclide, and organic contaminants in soil, surface water, and ground water) not only affects natural resources, but also causes major strains on ecosystems. Interest in phytoremediation as a method to solve environmental contamination has been growing rapidly in recent years. This green technology that involved “tolerant plants” has been utilized to clean up soil and ground water from heavy metals and other toxic organic compounds. Phytoremediation involves growing plants in a contaminated matrix to remove environmental contaminants by facilitating sequestration and/or degradation (detoxification) of the pollutants. Plants are unique organisms equipped with remarkable metabolic and absorption capabilities, as well as transport systems that can take up nutrients or contaminants selectively from the growth matrix, soil or water. As extensive as these benefits are, the costs of using plants along with other concerns like climatic restrictions that may limit growing of plants and slow speed in comparison with conventional methods (i.e., physical and chemical treatment) for bioremediation must be considered carefully. While the benefits of using phytoremediation to restore balance to a stressed environment seem to far outweigh the cost, the largest barrier to the advancement of phytoremediation could be the public opposition. The long-term implication of green plant technology in removing or sequestering environmental contaminations must be addressed thoroughly. As with all new technology, it is important to proceed with caution.

Application of Green Technology Using Biological Means for the Adsorption of Micro-Pollutants in Water

It is true that the world we have today is not the world we use to know. The Covid-19 pandemic has paralyzed all sector, hence the need for safety and enabling environment for mankind is of high importance. Adsorption technology is far the best and cheapest treatment technology for water and has extensively proven its worth for the uptake of micro-pollutant from surface, ground and water which are the major channels of home water. Over the years activated carbon is considered as the most common and universally used adsorbent for the eradication of different types of micro-pollutants from water. The contamination of surface water by micro-pollutant is a potential threat for the production of high quality and safe drinking water. Adsorption operation onto granulated activated carbon (GAC) in fixed-bed filters is often applied as a remedying step in the synthesis of safe and drinkable water. Activated carbon actively tends to act as a carrier material for a thin usually resistant layer of microorganisms (mostly bacteria) that forms on the coat of various surfaces (biofilm), hence biological simplification can be an alternative removal approach that can be adopted in granulated activated carbon filters. To evaluate the capacity of biofilm to biologically simplify micro-pollutants, it is very imperative to distinguish adsorption from biological simplification (biodegradation) as a removal mechanism. Experiment was carried out under the operating condition of a temperature range of 6?C to 20?C with biologically activated and autoclaved GAC to assess the biological simplification by the biofilm adsorbed on the GAC surface. Five micro-pollutants were selected as model compounds, of which some of them were biologically simplified by the GAC biofilm. Additionally, we observed that temperature can increase or decrease adsorption. Conclusively, comparison was made on the adsorption capacity of granulated activated carbon used for more than 50,000 beds.

Tripartite evolutionary game and simulation study on enterprise green technology innovation

By constructing the evolutionary game model among the government,enterprises and consumers,the paper analyzes the condition that the profit and loss relationship of the game subjects and their behavior strategies reach the stable state in the green technology innovation system,and uses MATLAB to conduct data simulation analysis.The results show that the government,enterprises and consumers have path-dependent behavior choices.The larger the government incentive coefficient and subsidy coefficient is not the better,but the larger the subsidy and subsidy coefficient will hinder the green technology innovation.Government punitive measures will promote green technology innovation,but high innovation subsidies will restrain the government’s environmental regulation.Therefore,the government should further improve environmental regulation policies,increase enterprises’enthusiasm for green technology innovation and consumers’acceptance of green products,and promote the development of green technology innovation.

Digital Transformation and Green Technology Innovation in Manufacturing Enterprises: A Study Based on Big Data Text Mining

Digital transformation serves as a new driving force and engine for enterprise innovation.Meanwhile,the national strategy of carbon peaking and carbon neutrality has set new goals and requirements for the green development of the Chinese manufacturing industry.From the three-dimensional perspective of"strategy-resource-institution,"this paper explores the impact and mechanism of digital transformation on green technology innovation of Chinese manufacturing enterprises and the heterogeneous impact of the institutional logic of ownership structure.Using a sample of 1,016 A-share listed manufacturing companies on the Shanghai and Shenzhen Stock Exchanges from 2011 to 2019 and based on big data text mining and a negative binomial regression model,this study finds that:(1)Digital strategy significantly enhances green technology innovation capability of enterprises;(2)digital resource investment partially mediates the effect of digital strategy on the enhancement of green technology innovation capability;and(3)the ownership structure of enterprises plays a moderating role in the mediating relationship mentioned above.Specifically,compared to state-owned enterprises(SOEs),non-state-owned enterprises(NsOEs)show no significant difference in the stages where digital strategy promotes green technology innovation and guides digital resource investment.However,they demonstrate higher efficiency in transforming digital resource investment into green technology innovation.The robustness test indicates that the significant effect of digital strategy and resource investment on green technology innovation in enterprises remains valid in the medium term,with a continuous enabling effect.There is no significant difference between SOEs and NsOEs in the medium and long term in promoting green technology innovation through digital transformation.Further,introducing keyword text networks to explore the structural impact of digital strategy,this study finds that digital product and manufacturing strategy are adequate strategic dimensions to enhance green technology innovation capability,and digital financial strategy and digital marketing strategy have no direct promoting effect on green technology innovation of enterprises.From the perspectives of strategies,resources,and institutions,the research findings elucidate the process mechanisms of digital acceleration in the green transformation of manufacturing and the heterogeneous effect of ownership structure and provide critical theoretical insights into the role mechanisms and contextual factors of digitalization on green innovation in manufacturing enterprises.Moreover,this study offers scientific decision-making support for incentivizing the manufacturing industry to seize the opportunities of industrial digitalization and accelerate carbon peaking and carbon neutrality.

Managers'Digital Literacy and Corporate Green Technology Innovation

This paper incorporates individual digital literacy into corporate management practice to explore the relationship between managers'digital literacy and the performance of corporate green technology innovation.The results show that managers'digital literacy can contribute to corporate green technology innovation.Specifically,a greater degree of digital literacy among the top management team is associated with better performance in corporate green technology innovation.Even if the management does not have an educational background in core digital technologies,their work experience related to core digital technologies such as computers and information technology can help promote corporate green technology innovation in the later stage.There is the heterogeneity in the managers'digital literacy role in promoting corporate green technology innovation,which is more significant in the sample of regions with low levels of the digital economy development,sufficient media attention,and non-heavily polluting enterprises.Digital transformation plays a mediating role between managers'digital literacy and corporate green technology innovation.Through further research,we find that the improvement of managers'digital literacy can contribute to the enhancement of corporate value in the future.The conclusions enrich the research horizon of upper echelons theory,explore the value and differentiated effect of digital human capital in the new era,and provide empirical evidence at the micro level that digital technologies promote the green and sustainable development of the economy.

Digital Transformation, Market Competition, and Corporate Green Technology Innovation

This paper selects China's A-share listed companies from 2012 to 2021 as the research sample and explores the impact of digital transformation on corporate green technology innovation and the moderating role of corporate competitive position in this relationship.The research findings are as follows:Digital transformation plays a significant role in promoting corporate green technology innovation.The improvement of corporate competitive position weakens the promoting effect of digital transformation on corporate green technology innovation.The moderating effect of the corporate competition position is more pronounced in the enterprises of the eastern and western regions,as well as in the listed companies in the manufacturing industry.The promoting effect of digital transformation on utility model patent innovation is dramatically attenuated when the corporate competitive position is strengthened.However,the weakening effect on invention patent innovation is not statistically significant.

Are the Green TBTs a Stimulus or a Trap for Enterprises’Green Technology Development?

Green trade barriers are often seen as a catalyst that promotes exporting countries to develop green technologies.However,by distinguishing the green technology behavior of enterprises into green technology transformation and green technology innovation,this paper finds that although green trade barriers can encourage enterprises in exporting countries to increase investment in green technology transformation in order to obtain rapid market access,they crowd out the resources of green technology innovation of enterprises.In other words,green trade barriers will strengthen enterprises’dependence on the introduction of green technologies,weaken their innovation capabilities,and increase the risk of being locked in the middle of the global industrial chain,creating a trap effect.Using the data of enterprises in the heavily polluting industry of A-shares from 2009 to 2021,this paper confirms the existence of the trap effect.In addition,this paper finds that due to the infl uence of short-sightedness of managers,alleviating corporate financing constraints can enhance the promotion effect of green trade barriers on the green technological transformation of enterprises,but cannot reduce its inhibiting effect on green technology innovation.The study also finds that even if the time window is extended to the medium and long term,green trade barriers cannot have a significant positive impact on enterprises’green technology innovation.Therefore,the government should not overestimate the role of green trade barriers in encouraging green development and green technology innovation,nor should it rely too much on loose financing policies.In contrast,government should formulate targeted industrial policies to help enterprises overcome green trade barriers through technological innovation.

Green Technology Innovation under China's New Development Concept:The Effects of Policy-Push and Demand-Pull on Renewable Energy Innovation

Green technology innovation meets the dual expectation of innovative development and green development perspectives.Under the canonical demand-pull and policy-push theories,a long-term mechanism for green technology innovation could be formed through upstream policy push and downstream demand-pull.Leveraging China's regional carbon emission trading scheme pilots as a quasi-natural experiment,this paper examines the policy-push and demand-pull effects on innovation in renewable energy patents.The data pertain to the city-level renewable energy patents from 2000 to 2020.Based upon the triple difference-in-difference method,results suggest that both policy-push and demandpull factors exert positive effects on innovation.This paper further explores the practical and theoretical implications of green technology innovation under the new development perspective.

The Impact of Cost Sharing on Green Technology Investment in Competing Supply Chains

The investment in green technology in the process of product design and production is viewed asa powerful tool for sustainable development and carbon emission reduction However,the substantial cost and pressure of competition weaken incentives for manufacturers to engage in green technology.In this paper,we consider two competitive manufacturer-retailer supply chains,where each manufacturer sells partially substitutable products through the exclusive retailer,study green technology investment selection by manufacturers,and examine the efficacy of retailer cost sharing scheme.Our analysis shows that a dominant equilibrium strategy for both manufacturers is to invest in green technologies,whether cost sharing is in place or not.Retailer sharing the cost of manufac turer green technology investment can avoid firms'preference confliction over the green technology investment and improve social welfare simultaneously when both the cost-sharing rate and the degree of product/channel competition are relatively low.We also find that green technology investment by manufacturers does not necessarily curb total carbon emission,and the cost sharing can either strengthen or weaken the carbon emission reduction of green technology investment.

From laboratory research to industrial application:a green technology of fluidized mineral processing for manganese dioxide ore reduction

The efficient utilization of manganese dioxide(MnO_(2))ore is essential for the sustainable development of manganese(Mn)industry.Confronting the great challenge of chemical engineering scale-up,a commercial fluidized reduction project of MnO_(2)ore with the capacity of 200,000 t a^(-1)is carried out based on deep experimental investigation,extensive kilogram-scale test and detailed engineering design.Compared with other production technologies and equipment,it is proved that the fluidized process shows distinguished advantages of lower energy consumption,higher production efficiency,larger automation degree and less environmental pollution.The comprehensive studies of experiment,modeling,simulation and optimization are required for a more promising development of fluidization engineering in the future.

The Effect of Green Technology Adoption Strategy on Duopoly Competition

Given consumers’trade-offs between conventional economic and environmental attributes of products,we provide a game-theoretic model to explore the role of GTA strategy in duopoly competition by incorporating two salient features:Two product types—The green product produced by a firm with GTA strategy and the ordinary product produced by a firm without GTA strategy,and two consumer segments,i.e.,the green consumers who are willing to pay for green products and the ordinary consumers who are willing to pay for ordinary products.Our analysis shows that GTA strategy may either increase or decrease the green firm’s quality provision.The subtle relationship between the green firm’s quality strategy and GTA strategy not only affects its own equilibrium performances but its rival’s.We also find that two consumer segments may be better off in the presence of a lower GTA intensity.Additionally,although the GTA strategy benefits the environment,the GTA investment is not the more the better.Finally,we find that GTA strategy would lead to higher social welfare only when the GTA efficiency is high enough.Our work not only provides an alternative economic explanation why some firms choose to implement GTA strategy and some do not in reality,but gives managerial insights for firms with different GTA strategies as well as policy insights for the social planner.

The Technology of Green Chemistry and Its Function in Redox Response and: Environmentally Friendly Technology for Sustainable Development: Assessment of Recent Findings
