Electric vehicles (EVs) have prominent advantages for reducing CO₂ emissions and alleviating the dependence on fossil fuel consumption in the transport sector. Therefore, many countries have set targets for EV development in recent years and have employed a number of policies to achieve environmental objectives and alleviate the energy pressure. Despite the fact that the adoption of EVs has increased in the past few years, more policies, such as financial incentives, technology support or charging infrastructure, should be made by governments to promote broader range use of EVs. In this paper, we review the relevant policies that different countries may adopt for stimulating the market of EVs. Based on this, we analyze the relationship between the policies and the adoption of EVs by taking America as an example. In conclusion, some effective policies are summarized to spur the market. Therefore, each country should learn from each other and employ effective policies based on the actual situation.

China had set an ambitious development target of electric vehicles (EVs) to mitigate the environmental pollution. However, the actual situation of EVs far lagged behind the goals. This paper analyzes the elements impeding EVs’ development, which are identified into four contributors, including deficient EV subsidy policies, embarrassed EV market, local protectionism, and unmatched charging infrastructure. Based on the actual situation of China, this paper discusses corresponding policy suggestions and explores the alternative roadmap of EVs. In the initial development stage of EVs, it is important to select the appropriate charging mode for EVs according to different characteristics across users. Moreover, the development of hybrid electric vehicle (HEV) may open the EV market faster than battery electric vehicle (BEV). In addition, the low-speed EVs may be a good choice for the rural market and should be well developed. With the promotion of EVs, China central and local governments should make rational policies to promote EVs’ development, which is the crucial force to drive the uptake of EVs.

The study was carried out to investigate the empirical effect of a strategic management system on sustainable development by using a balanced scorecard (BSC), as a theoretical lens, and organizational performance, as an intervening variable. The study incorporated a positivism research paradigm in order to address the objective nature of research. As the current study has an empirical and impartial nature, a quantitative method was considered the best method for achieving the research objectives of the study. The study used questionnaires as a data collection instrument. In total, three hundred questionnaires were disturbed among Chinese power companies based in Pakistan. A stratified-random sampling approach was adopted to reach relevant respondents. Partial least squares-structural equation modeling was used for statistical analysis. BSC indicated a positive influence on sustainable development. Additionally, organizational performance depicted partial mediation between the strategic management system and sustainable development. The study underpins the theoretical foundation of a resource-based view (RBV) and a balanced scorecard view of the strategic management system. The findings suggest that non-financial measures have better consequences for employees’ performance, making them ecologically responsive, unlike the financial performance measures used previously. The study suggests taking measures related to wastage and usage of inimitable resources that focus on in-addition rather traditional measures, which can allow sustainable development.

The economic operation of battery swapping stations (BSSs) is significant for the promotion of large-scale electric vehicles. This paper develops a linear programming model to maximize the daily operation profits of a BSS by considering constraints of the battery swapping demand of users and the charging/discharging balance of batteries in the BSS. Based on the BSS configuration and data from electric taxis in Beijing, we simulate the operation situation and charging/discharging load of the BSS in nine scenarios with two ordered charging and discharging strategies. The simulation results demonstrate that the model can achieve the maximum daily profits of the BSS. According to the sensitivity analysis, the battery swapping price for batteries is the most sensitive, followed by the number of batteries in the BSS, while the operation-maintenance costs and battery depreciation costs are least sensitive. In addition, the charging and discharging of batteries in the BSS can be coordinated by increasing the battery quantity of the BSS and formulating the ladder-type battery swapping price.

This paper investigates the development trends and variation characteristics of China’s economy, energy consumption and carbon emissions from 2007 to 2030, and the impacts on China’s economic growth, energy consumption, and carbon emissions under the carbon tax policy scenarios, based on the dynamic computable general equilibrium (CGE) model. The results show that during the simulation period, China’s economy will keep a relatively high growth rate, but the growth rate will slow down under the benchmark scenario. The energy consumption intensity and the carbon emissions intensity per unit of Gross Domestic Product (GDP) will continually decrease. The energy consumption structure and industrial structure will gradually optimize. With the economic growth, the total energy consumption will constantly increase, and the carbon dioxide emissions are still large, and the situation of energy-saving and emission-reduction is still serious. The carbon tax is very important for energy-saving and emission-reduction and energy consumption structure optimization, and the effect of the carbon tax on GDP is small. If the carbon tax could be levied and the enterprise income tax could be reduced at the same time, the dual goals of reducing energy consumption and carbon emissions and increasing the GDP growth can be achieved. Improving the technical progress level of clean power while implementing a carbon tax policy is very meaningful to optimize energy consumption structure and reduce the carbon emissions, but it has some offsetting effect to reduce energy consumption.

This paper develops a hybrid computable general equilibrium model to explore the impacts of reducing renewable energy subsidies on China's energy transition in various scenarios. The results of the benchmark scenario indicate that China can realize its regulatory goals in energy consumption and structure and carbon emission intensity in 2030. This paper sets various policy scenarios to simulate the impacts of reducing renewable subsidies between 2021 and 2030. The analytical results of the scenarios indicate that the government's 2030 target for total energy and natural gas consumption and carbon emission intensity can be achieved. However, the target for non-fossil energy is hard to fulfill when the renewable energy subsidy is reduced. The empirical results also indicate that a moderate renewable energy subsidy associated with significant technical progress in renewable energy is a crucial way for China to fulfill government targets and energy transition in 2030.
