中国碳交易政策扩散的影响因素、路径差异与减碳效果研究——基于省域数据的实证分析

碳交易市场的建设有助于实现全球碳平衡,而碳交易政策扩散对于促进中国碳交易市场的持续健康发展有着重要的现实意义。在我国碳交易市场建设不断深化的情境下,有必要识别省域碳交易政策扩散的多维影响要素,检验不同扩散路径下的政策效果差异,总结政策扩散经验。文章基于省域面板数据,首先运用事件史分析法,通过Cox比例风险模型发现,能源政策的落实、地方政府的综合服务能力和社会创新能力是碳交易政策扩散的关键驱动要素;其次,利用合成控制法进一步检验,发现主动扩散地区的减排效果弱于试点扩散地区,试点扩散地区对主动扩散地区的激励和带动作用有限,试点成果尚未得到有效学习和复制。为此,在我国统一碳交易市场的建设过程中,应强化中央统筹协调与地方相关举措之间的协同配合,依托有力的政策驱动激发我国碳交易制度活力,提升碳减排效果,形成路径清晰、梯度有序的政策扩散机制,以稳步实现2030“碳达峰”、2060“碳中和”的目标。     

英国的“低碳转型计划”及其政策启示

作为低碳经济的先行者，近来英国正式颁布了低碳转型计划。该计划对电力部门、家庭与社区、工作场所和就业、交通系统、农业等领域的碳排放都给出了详细的应对措施，将减排目标具体量化，并在此基础上提出了明确的时间表。与此同时，计划还突出强调政府在低碳转型中的定位和作用。该计划对我国发展低碳经济具有重要启示。     

Informed Public Preferences for Electricity Portfolios with CCS and Other Low‐Carbon Technologies

Public perceptions of carbon capture and sequestration (CCS) and other low‐carbon electricity‐generating technologies may affect the feasibility of their widespread deployment. We asked a diverse sample of 60 participants recruited from community groups in Pittsburgh, Pennsylvania to rank 10 technologies (e.g., coal with CCS, natural gas, nuclear, various renewables, and energy efficiency), and seven realistic low‐carbon portfolios composed of these technologies, after receiving comprehensive and carefully balanced materials that explained the costs and benefits of each technology. Rankings were obtained in small group settings as well as individually before and after the group discussions. The ranking exercise asked participants to assume that the U.S. Congress had mandated a reduction in carbon dioxide emissions from power plants to be built in the future. Overall, rankings suggest that participants favored energy efficiency, followed by nuclear power, integrated gasification combined‐cycle coal with CCS and wind. The most preferred portfolio also included these technologies. We find that these informed members of the general public preferred diverse portfolios that contained CCS and nuclear over alternatives once they fully understood the benefits, cost, and limitations of each. The materials and approach developed for this study may also have value in educating members of the general public about the challenges of achieving a low‐carbon energy future.     

尖镰孢菌F.oxysporum L19内切纤维素酶诱导碳源的研究

以在自然界中筛选到的一株产纤维素酶的丝状真菌尖镰孢菌F.oxysporumL19为材料,定时测定尖镰孢菌在10种碳源中的纤维素酶活力,发现酶的合成受培养基中碳源种类的调节控制。结构相对完整的纤维类物质(微晶纤维素、TYPE50、CMC、醋酸纤维素)诱导活性较高,二糖(乳糖、麦芽糖、蔗糖)和单糖(葡萄糖和D-木糖)几乎没有诱导作用,麸皮汁液体培养液表现出了较高的诱导活力。菌丝在麸皮汁培养液上的生长状况的研究表明,菌丝的生长情况与酶的产生存在不同步性。这为下一步酶的纯化和分子生物学的研究中选择不同生长期的培养也提供了依据。     

Do greater amounts of FDI cause higher pollution levels? Evidence from OECD countries

Using an ARDL model for a panel of 15 OECD countries, this work analyses the impact that FDI, both jointly and by sector, has on CO₂ emissions. The findings reveal that these countries are yielding to the pressure on the trade sector. Unexpectedly, gross fixed capital formation shrink pollution, excluding in the mining sector. With findings supporting the Pollution Haven Hypothesis, policymakers must pay attention to FDI inflows, ensuring that FDI place high importance on the transfer of green technologies to improve the efficiency. These goals could be achieved through an increase in the stringency of environmental laws within the host countries, especially the ones related to FDI.     

Carbon Emissions Abatement (CEA) allocation and compensation schemes based on DEA

As environment constraints on economic growth are strengthening, Carbon Emissions Abatement (CEA) allocation becomes a significant issue that draws academia׳s attention. In the literature, the Data Envelopment Analysis (DEA) technique has been applied to obtain CEA allocation with centralized models. Nevertheless, a centralized allocation plan suffers from an implementation difficulty in persuading decision-making units (DMUs) into an agreement. In this paper, we propose a new two-step method to mitigate this side effect. In the first step, we provide improved DEA-based centralized allocation models under the assumptions of constant returns-to-scale (CRS) and variable returns-to-scale (VRS) respectively and in the second step, two compensation schemes are developed for centralized allocation plans. An empirical application to the countries in Organization for Economic Co-operation and Development (OECD) is presented to elaborate the main idea.     

CO2气体冷却器性能测试实验台设计

为了对CO2气体冷却器进行系统全面的性能分析,根据CO2制冷剂在亚临界区和超临界区的换热特性,以第二制冷剂量热器法和水冷气体冷却法为理论基础,结合企业实际测试需求研制了能够全面测试CO2气体冷却器性能的实验台。其可测试的换热量范围是1.6~32.0 kW,测量精度高。实际选用了一个气体冷却器做验证,结果显示2种测量方法的偏差小于4%,满足企业验收标准。此实验台的设计可为相关性能测试实验台的研究提供借鉴。     

消费者低碳消费行为的心理归因和政策干预路径:一个基于扎根理论的探索性研究

引导消费者的生活方式和消费模式转向低能耗、低污染、低排放的方向是当前一个重大课题。然而,消费者为什么会实行低碳消费行为模式(即低碳消费行为归自何种心理)?如何促进和引导消费者的低碳消费行为(即低碳消费行为如何才能持续)?对于这两个关键性问题目前还缺乏深度的研究。本文通过深度访谈,应用扎根理论这一探索性技术探究低碳消费行为的深层次心理归因(解决第一个问题)及相应的政策干预路径(解决第二个问题)。研究发现,个体心理意识、社会参照规范两个主范畴是低碳消费行为的内部和社会心理归因。但它们对于低碳消费行为的促成机理并不一致:个体提高心理意识产生相应的低碳消费行为,这归于认知性学习范畴;个体观察参照群体的消费模式及其结果产生特定的低碳消费行为,这归于观察性学习范畴。不同心理控制源的个体(内控型还是外控型)之间也存在一定的差异。低碳传播沟通和情境结构变革两个主范畴是低碳消费行为的政策干预变量,且它们是相互补充、相互配合的。通过传播沟通影响个体心理意识、社会参照规范,通过情境结构变革影响低碳消费行为的成本收益结构成为主要的政策干预路径。这些研究结论可以为政府制定有效的干预政策,为引导消费者的消费行为模式提供理论基础和政策借鉴...     

后京都时代的碳关税制度及其对我国的启示

碳关税制度最早为欧盟提出,近期美国众议院通过的《美国清洁能源与安全法》规定了碳关税制度。碳关税的实施将会导致我国相关产品的出口额下降、恶化我国的出口环境并导致我国高碳产业的离岸发展。碳关税制度因违反最惠国待遇原则和约束关税制度而与国际贸易法存在冲突,但是它因符合GATT第20条（b）款和（g）款而与国际贸易法相协调。碳关税对我国具有三方面的启示：第一,碳关税折射出国际法的不成体系性;第二,在多边体制内解决碳关税问题是可行的;第三,在国内应当大力发展低碳经济。
