| Strategic extended producer responsibility can double China’s formal electric vehicle battery
|
2026-04-29 |
|
Abstract:China’s booming electric vehicle (EV) sector is generating a rapidly growing stream of retired batteries, most of which still enter pollution-intensive informal recycling channels. How to redirect these batteries into formal recycling remains unclear, particularly given the complex and dynamic interactions among governments, producers, consumers, and informal recyclers. Here, we devel...

| The impact of pollution transmission networks in a transboundary pollution game
|
2026-04-29 |
|
摘要：To explore transboundary pollution games with network externalities, this study develops a multi-region differential game which investigates the interaction and co-evolution of multiple pollution stocks across a continuous horizon. Pollution transmission networks are incorporated into the model via an adjacency matrix, detailing transmission paths of pollution across regions. Equilibrium ...

| 区域间碳交互过程下的策略分析与碳市场影响研究
|
2026-04-29 |
|
摘要：针对二氧化碳流动性引发的区域间碳交互问题，本文于碳市场背景下探讨了分散决策与集中管理两种模式下的区域碳管理策略，探究出各区域策略的演化趋势与碳减排效果，并提供区域实现特定碳治理效果的市场条件。结果表明1）碳市场价格波动对区域内碳存量与管理策略演变产生异质性调控效果，且影响区域治理效果在两种模式下的占优特性。2）分散决策下提高博弈持续时间可明显降低区域碳产出的增长率，还可管控区域碳吸收的下降...

| 数据为证：各类煤矿事故致因差异化分析与危险源管控研究
|
2026-04-29 |
|
论文摘要：为分析各类煤矿事故致因要素间的差异，本文构建了基于危险源和隐患的事故致因模型，并以事故文本数据为证据来源展开研究。首先，提取煤矿安全生产过程中人员、设备、环境和管理4类危险源的外在表现形式；其次，将TAN贝叶斯网络模型和Apriori关联算法作为证据生产方法，利用前者分析煤矿事故类型与事故致因的关系，借助后者从管理的角度找出各类煤矿事故中亟须重点防控的有关员工、设备和环境的不安全要素。研究发现：...

| Enhancing the understanding of China's wind power development: Spatial-temporal dynamics an
|
2026-04-29 |
|
Abstract:As China's wind power industry shifts from scale expansion toward value enhancement, improving development performance increasingly depends on coordination across segments of the industry chain. This study provides a comprehensive analysis of China's wind power development (CWPD) from a whole industry chain perspective, covering innovation, investment, production and consumption. Using...

| Measurement and Promotion Strategy of China’s Power System Regulation Capacity
|
2026-04-29 |
|
Abstract:Power system regulation capacity is the key factor affecting the development and consumption of renewable energy. Based on China’s policy to promote the consumption of renewable energy, this paper constructs an evaluation index system of power system regulation capability covering four dimensions: the supply side, grid side, load side, and support system. The entropy method is used to...

| Price elasticity of electricity demand in China– A new instrument variable based on marketization
|
2026-04-29 |
|
Abstract:Estimating the price elasticity of the demand for electricity is important in research on the economics of electricity. However, the conventional approach of using average electricity prices as explanatory variables introduces endogenous challenges, such as measurement errors and reverse causality. In this study, we provide a novel analysis of China's coal and electricity marketization...
