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. 展开更多

Promoting agricultural modernisation through technological change is an important strategy for China.China's carbon neutrality strategy is leading to systemic socio-economic changes that could exacerbate the uncertainty of agricultural development.Therefore,applying a computable general equilibrium(CGE)model,this study characterises the agricultural sector in detail,introducing endogenous technological change proxied by research and development(R&D)to assess the impact of different technological change scenarios on agricultural development under the carbon neutrality target.The results show that allocating carbon revenue for R&D inputs can mitigate the significant negative impact of achieving carbon neutrality on knowledge capital and production in agricultural sectors.Overall,using carbon revenue only for R&D input in crop sectors has the optimal effect on increasing the agricultural sectors'knowledge capital,improving crop production and profit,reducing crop external dependence and promoting the synergistic reduction of carbon and pollutant emissions.However,this scenario has the largest negative impact on macro-economics and household welfare.In contrast,allocating carbon revenue to promote technological change in broader non-energy sectors or both crops and non-energy sectors can effectively mitigate negative socio-economic impacts,but the positive impact on agricultural development is minimal.These findings provide practical insights for the rational use of carbon revenue to expand agricultural R&D investment and ensure balanced agricultural and economic development under the carbon neutrality target. 展开更多

This article explores the effects of investment upon energy intensity by applying a unique panel data of China's 27 provinces between 2004 and 2013.In addition,it also particularly stuthes other factors,such as energy price,economic structure,and urbanization.The results,based on four econometric regression model results,suggest that in general,the indigenous investment on research and development is a more powerful tool to decrease China's energy intensity regardless of region disparity.The foreign direct investment(FDI) has a prominent but not persistent effect on energy intensity.However,the outward direct investment has not shown its significant impact on energy intensity.At the level of an aggregate economy and China's eastern region,the results demonstrate that FDI improves energy efficiency significantly.For the central and western provinces,FDI does not support the similar conclusion.Based on these analyses,we present the corresponding regional policies for policymakers. 展开更多

In recent years, China has promulgated many laws and regulations of environmental protection, gradually forming an environmental regulation system, and most enterprises are under the dual pressure of environmental protection and business performance. It would be a significant way that enterprises undertake R&D activities for a change. This paper is based on the Shanghai and Shenzhen A-share listed heavy pollution enterprises in 2011-2016, which is based on the review and summary of research results of former researchers, combining with current environmental regulation situation of our country, raising the relevant hypothesis between environmental regulations, R&D investment and business performance against heavy pollution industry. Adopting the method of empirical research, it also built the linear regression model which employs the relevant financial data of heavy-polluting enterprises in China as the statistical research sample. The relationship for heavy-polluting enterprises affected by environmental regulations between environmental protection R&D investment and enterprise business performance was tested. The results show that there is a positive influence on the environmental R&D investment and business performance, and a lag effect upon the R&D investment of enterprises to business performance. Finally, the research results were used to evaluates problems existing in the R&D investment on pollution industry in China as well as business performance and we put forward some suggestions on improving environmental regulation standards and technology innovation consciousness as well as optimizing the structure of R&D investment. 展开更多

The super-deduction of research and development(R&D)expenses is at the core of the policy to stimulate enterprise innovation in China.This paper identifies whether firms are supported by the super-deduction policies for R&D expenses and uses the diferencein-diferences method to investigate the impact of the policies on R&D investment.The results show that changes in policy in 2013 significantly increased the R&D investment of firms engaging in key state-supported technologies.Policy changes in 2016 significantly increased the R&D investment of firms engaging in non-key-state-supported technologies.Enterprises not only invested all their tax incentives in R&D activities but also increased their investment in self-raised funds.The super-deduction policy had different impacts on different industries,firms with different boards,and firms with diferent ownership.The policy significantly affected the manufacturing and construction industries,the Small and Medium Enterprise Board,and non-state-owned enterprises.Through a mechanism analysis,we found that the policy significantly reduced the user cost of R&D and increased the net cash flow of enterprises,which could raise a firm's R&D investment.It is necessary to increase policy support,expand the scope of super-deductible expenses,and increase the super-deduction rate based on industry classification according to the sensitivity of different industries to the policy. 展开更多

Research is essential for improvement of agricultural productivity,resource use and resilience,and for food systems transformation more broadly.This article analyzes the drivers of past agricultural productivity growth in low-and middle-income countries(LMICs)and argues that productivity is not growing fast enough to meet the needs of a global population of 10 billion by 2050.A sustainable transformation of agri-food systems in LMICs will need greater and faster technical change.Higher investment in agri-food R&D is therefore needed to accelerate productivity growth and address the social,economic,nutritional and environmental challenges facing LMICs.Greater and bettertargeted investment in sustainable technologies and climate change mitigation and adaptation will be particularly important to reducing the climate change impacts on agriculture and food security in the coming decades.However,LMICs with small research systems and limited innovation capacity lack the scale and resources to effectively tackle the challenges ahead.Better coordination and a clear articulation of roles and responsibilities among national,subregional,regional and global R&D actors(both from the public and private sectors)are essential to ensuring that scarce financial,human,and infrastructure resources are optimized,duplications minimized,and synergies and complementarities enhanced. 展开更多
