China has commenced a high-quality development phase, necessitating significant promotion of the digital economy (DE), which includes green advancement as its foundation. Transitioning from a DE into high-quality development requires advancing the concept of new quality productivity (NQP), which unequivocally delineates the direction of Chinese socio-economic progress. Therefore, this study developed a new quality productivity indicator model encompassing three components aligning with NQP: (i) scientific and technological, (ii) green, and (iii) digital productivity. The analysis investigated the crucial role of the NQP in achieving the “double carbon” goal within the DE by utilizing panel data from 30 Chinese provinces between 2012 and 2022. Consequently, the DE substantially reduced carbon emissions (CEs) and exhibited a notable spatial spillover effect. The impact coefficient of the DE on CEs is −0.0583, which is significant at the 1% level. The direct effect and indirect effect analysis revealed that the inhibition effect of the DE on regional CEs was −0.0725 and −0.0964, respectively (significant at the 1% level). The heterogeneity outcomes denoted lower carbon emissions in non-resource-based regions due to the DE. Nevertheless, this process did not exhibit the same impact on resource-based regions. Furthermore, the NQP functioned as the intermediary factor in the correlation between DE development and CEs. This outcome then led to three critical recommendations: (i) the complete release of the digital dividend, (ii) enhanced government attention toward low-carbon environmental protection, and (iii) the establishment of a green technology innovation platform to achieve higher rates of NQP development.

Data have become a virtual factor of production, and when integrated with the traditional factors of labor, capital, and land form digital labor, digital capital, and digital land, thereby generating a multiplier effect that contributes to the comprehensive revitalization of rural areas. This paper utilizes panel data from 30 provinces (autonomous regions and municipalities) in China from 2013 to 2023 and employs a double machine learning model to empirically test the impact mechanism of rural digitalization on the integration of rural industries. The results indicate that digital villages significantly promote the integrated development of rural industries through three direct pathways—digital industry development, digital information infrastructure, and digital service levels—with this conclusion remaining valid after a series of robustness tests. A mechanism analysis shows that digital villages facilitate the integration of rural industries through three indirect pathways—alleviating urban–rural factor mismatches, adjusting the agricultural–industrial structure, and promoting agricultural technological advancement—with this conclusion still valid after various robustness tests. The heterogeneity results show that there is significant variability in how digital villages promote the development of integrated rural industries, with the effects being more pronounced in major grain-producing and eastern regions compared to non-major grain-producing and central-western regions. Based on this, this paper proposes policy recommendations focused on accelerating digital village construction, formulating differentiated strategies, and alleviating factor mismatches, aiming to provide references for achieving rural revitalization. We mainly propose countermeasures and suggestions from three aspects: digital dividend, differentiation strategy, and element mismatch. Our main purpose in writing this article is to make up for the shortcomings of existing theories, enrich the theoretical system of digital rural construction, contribute Chinese solutions for digital rural construction around the world, and improve the word’s level of digital rural construction.

The impacts of the COVID-19 pandemic have sparked global debate over how green economic recovery may and should be, and if the pandemic has accelerated the present energy transition while assuring a just transition for vulnerable populations such as unskilled workers and women. This study investigates the socioeconomic impact of South Africa’s planned green energy transition, with a focus on the Mpumalanga province—the country’s largest coal mining region with many coal-fired power plants. Using a regional-dynamic computable general equilibrium (CGE) model, the study analyses the economy-wide effects of different policy scenarios related to a changing electricity generation mix, investment financing costs, and international action against non-compliant industries, amongst others, with a specific focus on the vulnerable industries and population groups in Mpumalanga. Key results from the study highlights that (1) the structure of the Mpumalanga economy will be affected in the medium to long run regardless of the domestic transition path, (2) the Mpumalanga economy is indeed in danger of shrinking relative to the baseline, unless the Just Energy Transition (JET) is quickly and carefully managed, and (3) at a national level, at least, there is the strong possibility of a double dividend when greening the South African economy with overall economic growth and environmental outcomes expected to improve in the long run.

In order to cope with the climate problem of global warming and respond to the call of the United Nations to reduce carbon emissions, China has put the goals of carbon peaking in 2030 and carbon neutrality in 2060 forward and has promoted the transformation and upgrading of the economic development mode and the green, low-carbon development path. In international practice, various countries have widely adopted the carbon trading market and tax policy as effective carbon emission reduction mechanisms and tools. In 2012, China implemented a carbon trading pilot project and established a national unified carbon trading market in 2021 based on accumulated experience, but the carbon tax has not yet been introduced. According to the international carbon tax practice and the current situation in China, the introduction of the carbon tax is conducive to the establishment of a sound carbon emission reduction system and the promotion of green and low-carbon development from the macro-control level. In this paper, we analyzed the necessity and theoretical research of carbon tax policy in China and explored the feasibility of a carbon tax in China by combining the internationally advanced carbon tax practice. By establishing a CGE model at the carbon-tax level and using the social accounting matrix (SAM) as the database, we simulated the impact of implementing carbon tax policies under different carbon tax prices on China’s environmental and economic benefits and whether the double-dividend effect of a carbon tax can be effectively realized. The results show that the carbon tax will help reduce carbon emissions and significantly affect carbon reduction. However, in the short term, it has a negative effect on economic development. Accordingly, it is suggested that a scientific carbon tax system should be established according to national conditions, and a carbon tax should be introduced at a lower carbon tax price. The carbon tax should be supplemented by carbon tax subsidies to ensure effective carbon emission reduction so as to alleviate the inhibiting effect on economic development. At the same time, the compound carbon emission reduction mechanism of carbon trading and tax should be improved to lay the institutional foundation for the early realization of the carbon neutrality target.

The rapid development of energy consumption and carbon emissions in the construction industry poses an enormous and negative challenge for China’s energy and environment. While maintaining moderate economic growth, it is particularly important to realize energy conservation and carbon reduction. Carbon tax policy, a direct tool to reduce carbon emissions, can effectively alleviate the environmental issues caused by construction activities. However, relying solely on a single method is insufficient to handle the complicated circumstances of China’s construction industry. This study explores the influence of carbon tax on the construction industry through adjustments to tax rates via developing a Computable General Equilibrium (CGE) model. Then, it analyzes how the carbon tax affects the economic and environmental variables by designing scenarios for recycling tax revenue and improved energy efficiency. The results indicate that the carbon tax rate of 40 RMB/t-CO₂ is the most appropriate. At this tax level, the negative impacts of energy demand and emissions reduction on macroeconomy and construction industry are minimized. It was also determined that carbon tax revenue recycling to households and sectoral investment will realize the “weak double dividend” effect on the construction industry. Furthermore, improving energy efficiency in the construction industry will demonstrate the additional advantages of carbon tax. This study serves as a theoretical foundation for the Chinese government to develop various energy strategies to achieve low-carbon development in the construction industry. Full article

Existing studies have examined the double dividend effect of environmental protection tax. However, less attention has been paid to the influencing factors and transmission paths of the pollution abatement effect of the environmental protection tax. Based on the panel data for 30 of China’s provinces from 2007 to 2019, this study discusses the environmental protection tax’s influencing factors and transmission paths on the emission scale and intensity of different air pollutants through the panel threshold regression model and mediating effect model. The results show that: (1) the environmental protection tax has a positive emission reduction effect on the emission scale or emission intensity of sulfur dioxide (SO₂) and nitrogen oxides (NO₂); (2) the abatement effect is stronger when per capita gross regional product is above the threshold value; (3) technological progress, economic growth, and industrial structure all have positive mediating effects. Therefore, the local environmental protection tax rate should be set with comprehensive consideration of regional economic development, industrial structure, and technological progress. Full article

By originally integrating the structural decomposition analysis (SDA) into a computable general equilibrium (CGE) model, this paper simulates and analyzes the impact and mechanism of energy taxes on carbon emissions. Changes in carbon dioxide emissions, energy consumption structure, and other macroeconomic variables are investigated under different pre-set scenarios. The conclusion shows that the imposition of an ad valorem energy tax will indeed impact the production and consumption of enterprises. A higher tax rate leads to more pronounced reductions in carbon dioxide emissions. The carbon intensity effect is the dominant factor driving national carbon emissions and carbon emission intensity decline. Although the production structure effect and final demand effect play a role, their influences are relatively weak. While levying energy taxes, subsidies for personal income tax or corporate production tax can achieve double dividends. The progress of energy utilization technology is capable of increasing unit energy output and easing the negative impact of energy tax collection, and the gross national product may rise rather than fall. Under this circumstance, the production structure effect will play a greater role because the total demand coefficients of various industries for energy industry products will further decline. Only by levying energy taxes on coal and oil, exempting energy taxes on natural gas, or using energy tax revenue to subsidize investment in the natural gas industry can the government optimize the energy consumption structure. Subsidies will boost final demand for the natural gas mining and processing industry and increase the consumption share of natural gas, a cleaner energy source than coal and oil, which is critical in the current energy transition process.

Facing the increasingly severe environmental problems, the development of a green and sustainable low-carbon economy has become an international trend. In China, the core issue of low-carbon economic development is effectively resolving the contradiction between the exploitation and utilization of fossil energy and greenhouse gas emissions (mainly carbon emissions). Based on the SAM matrix, we established a static Computable General Equilibrium (CGE) model to simulate the impact of carbon tax policies on energy consumption, carbon emissions, and macroeconomics variables under 10, 20, and 30% emission reductions. Meanwhile, we analyze the impact of different carbon tax recycling mechanisms under the principle of tax neutrality. We find that the carbon tax effectively reduces carbon emissions, but it will negatively impact economic development and social welfare. A reasonable carbon tax recycling system based on the principle of tax neutrality can reduce the negative impact of carbon tax implementation. Among the four simulated scenarios of carbon tax cycle, the scenario of reducing residents’ personal income tax is most conducive to realizing the “double dividend” of carbon tax. Full article

Most previous articles estimate the effects of information communication technologies (ICTs) on economic growth average using national data without consideration of heterogeneity of ICT effects on cities across multiple economic development. The heterogeneity of ICT effects is confirmed to promote both the sustainability and equitableness of the whole cities. In order to investigate the heterogeneous effects of ICT between developed and less developed cities, a quantile spatial autoregressive (QSAR) model is applied to estimate coefficients at different quantiles while accounting for the spatial dependence of urban economy. We find significantly positive effects of ICT in local and neighboring cities after controlling the spatial dependence of urban economy. We have further found larger coefficients of ICT-related variables in cities with lower gross domestic product (GDP) per capital suggesting that digital dividend from ICT prefer the less developed cities over developed cities. Our conclusions indicate there would be “double dividend” from ICT, namely an improvement of both overall economic growth and balanced economic development among cities. Full article

Accurate and reliable power load forecasting not only takes an important place in management and steady running of smart grid, but also has environmental benefits and economic dividends. Accurate load point forecasting can provide a guarantee for the daily operation of the power grid, and effective interval forecasting can further quantify the uncertainty of power load on this basis to provide dependable and precise load information. However, most of the previous work focuses on the deterministic point prediction of power load and rarely considers the interval prediction of power load, which makes the prediction of power load not comprehensive. In this study, a new double hybrid load forecasting system including point forecasting module and interval forecasting module is developed, which can make up for the shortcomings of incomplete analysis for the existing research. The point forecasting module adopts a nonlinear integration mechanism based on Back Propagation (BP) network optimized by Multi-objective Evolutionary Algorithm based on Decomposition (MOEA/D) to improve the accuracy of point prediction. A fuzzy clustering interval prediction method based on different data feature classification is successfully proposed which provides an effective tool for load uncertainty analysis. The experiment results show that the system not only has a good effect in accurately predicting power load, but also can analyze the uncertainty of the power load, which can be used as an effective technology of power system planning.

In this paper, we build and analyze a general equilibrium model to evaluate the effects of environment tax reform on a small open economy in a “suboptimal environment” with existing tax distortions. We then use the macroeconomic data from the Chongqing Municipality in China to conduct simulations to empirically test our analytic results. Our main findings include the followings. First, an increase in environmental tax rate can effectively reduce the use of polluting consumer goods by households as well as investment in polluting factors by enterprises. Hence, an increase in environmental tax rate can improve environmental quality and obtain “environmental dividend”. Second, an increase in environmental tax rate can negatively impact employment, family income and economic growth. Hence, there is no “non-environmental dividend” effect. Third, an increased environmental tax rate has both substitution effect and income effect on household consumption. On the one hand, it motivates households to substitute polluting consumer goods with clean consumer goods. On the other hand, it lowers the total consumption level of households. Fourth, we show that the “double dividend” hypothesis on environmental tax is invalid. And the optimal environmental tax under the suboptimal environment is lower than the Pigouvian tax rate. Finally, we discuss the policy implications of our results. Full article

Based on a panel ARDL (AutoRegressive Distributed Lag) model, this paper investigates the environmental and economic consequences of energy tax levied in the four Nordic countries and the G7 countries from 1994 to 2016. Based on the double dividend theory of environmental tax, this paper investigates five variables: energy tax, energy consumption per unit of GDP, income tax, profit tax and capital gains tax, carbon dioxide intensity and fossil fuel burning ratio. A panel ARDL model is established to empirically test the relationship between energy tax and other variables. Experiments show that both the four Nordic countries and the G7 countries have found the existence of green dividends in the long run: the green dividends of the four Nordic countries are reflected in the reduction of carbon dioxide emissions, while those of the G7 countries are reflected in the reduction of fossil fuel use. In terms of blue dividends, the implementation of energy tax in the four Nordic countries can not only reduce distorted taxes in the short term, but also promote economic growth and adjust tax structure in the long term. For the G7 countries, blue dividends are not reflected in the long term. The model used in this paper is a panel ARDL model, which is more suitable for the study of multiple countries, multiple variables and long-term cycles. This model has been seldomly used in previous studies. The application of the panel ARDL model in this paper is not only more scientific and applicable, but also more innovative, which makes up for the shortcomings of previous studies. The research object of this paper selects the energy tax, which is an important part of the environmental tax system, and strives to provide a reference for the implementation of environmental taxation priorities and effects through empirical research. This paper may also serve as a reference for other countries to establish and improve environmental tax. As the first environmental tax law in China, the Environmental Protection Tax Law of the People’s Republic of China was formally implemented on 1 January 2018. This paper chooses G7 countries and Nordic countries as the research objects. As these are important economies in the world, their environmental tax implementation is more perfected and has strong representativeness. This study can provide some experience for the continuous improvement of China’s environmental tax law. Full article

OECD countries are the largest energy consuming economies in the world, improving energy efficiency and reducing pollution emissions is one of the important goals of the environmental tax policies of OECD countries. Based on the total factor energy efficiency index, this paper establishes an epsilon based measure-data envelopment analysis (EBM-DEA) model to measure the energy efficiency levels of 32 OECD countries during 1995–2016 when undesired outputs are included and not included. The effect of environmental factors on energy efficiency evaluation is compared by efficiency analysis and projection value analysis. On this basis, a Panel Logit model was established to empirically examine the impact of energy taxes on energy efficiency in 32 OECD countries. This paper finds that undesired output has a large impact on the energy efficiency level of OECD countries. Measuring energy efficiency levels without considering undesired outputs tends to lead to overestimation of the energy efficiency level of environmentally friendly countries and underestimate the energy efficiency level of countries that value environmental protection. The collection of energy tax has an important impact on energy consumption efficiency. Without considering the unexpected output, the energy tax has a significant impact on improving the efficiency of coal energy consumption. When considering the unexpected output, the energy tax has a significant impact on improving the efficiency of oil energy consumption. Regardless of the expected output or not, the energy tax has a positive effect on improving the efficiency of natural gas energy consumption. The experimental results also show that the energy structure and energy price have a negative impact on energy efficiency, while the progress of environmental protection technology and industrial structure have a positive impact on energy efficiency. Energy taxes have a “double dividend”. This paper argues that when evaluating a country’s energy efficiency, it should consider the undesired output factors of environmental constraints; governments should pay attention to the role of energy taxes in improving energy efficiency, improve the energy tax system, optimize industrial structure upgrades, stabilize energy prices and support the development of environmental technologies and improve energy efficiency.

We investigate the potential for double or even multiple dividends arising from a climate and energy tax reform (CETR), using a regional computable general equilibrium model. Such dividends indicate if government revenues raised from energy-related environmental taxes and recycled back to households or industries through (regional) social security contributions will yield welfare gains larger than gross cost. Building on existing double dividend theory, we broaden the scope by considering both social and regional aspects of a CETR. We explore the use of household transfers and regional payroll taxes as recycling instruments and investigate to what extent wage formation on the labor market has an effect. For Norway, our results indicate that a CETR may conflict with sub-national policy goals under all assessed scenarios. In particular, this holds for income inequality. Although our analysis concerns the social, economic and environmental aims of a Norwegian policy, the approach can be generalized to, e.g., a European context. Full article

An environmental fiscal reform (EFR) represents a transition of a taxation system toward one based in environmental taxation, rather than on taxation of capital, labor, or consumption. It differs from an environmental tax reform (ETR) in that an EFR also includes a reform of subsidies which counteract environmental policy. This research details different ways in which an EFR is not only possible but also a good option that provides economic and environmental benefits. We have developed a detailed dynamic CGE model examining 101 industries and commodities in Spain, with an energy and an environmental extension comprising 31 pollutant emissions, in order to simulate the economic and environmental effects of an EFR. The reform focuses on 39 industries related to the energy, water, transport and waste sectors. We simulate an increase in taxes and a reduction on subsidies for these industries and at the same time we use new revenues to reduce labor, capital and consumption taxes. All revenue recycling options provide both economic and environmental benefits, suggesting that the “double dividend” hypothesis can be achieved. After three to four years after implementing an EFR, GDP is higher than the base case, hydrocarbons consumption declines and all analyzed pollutants show a reduction. Full article
