This study focuses on a national regional coordinated development strategy and adopts China Multi-Regional Computable General Equilibrium model to analyze the economic and social development, energy demand, and carbon emissions of the provinces during the 14th Five-Year Plan (FYP, 2021 2025) period based on the economic development and energy demand since the New Normal. The main conclusions are the following: 1) Under the guidance of the regional coordinated development strategy, 13 provinces/municipalities are expected to have a per capita gross domestic product (GDP) of more than US$15,000, and 16 provinces/municipalities will have a per capita GDP of US$10,000 15,000. All provincial economies are expected to achieve steady and rapid development by the end of the 14th FYP. 2) The total energy consumption of the provinces is expected to reach 5.45 Gtce (excluding Tibet) in 2025, and the average annual growth rate is approximately 1.5%. The growth of energy demand will remain in low speed. The key point of energy demand will gradually shift from the eastern to the middle area, while the proportion of energy use in the western provinces will remain stable, which is consistent with the economic development stage and regional coordinated development strategy. 3) The annual average carbon intensity (mainly considering carbon emissions from energy use) of the provinces will approximately with most provinces dropping by over 4.0%. The trend of a considerable decline in carbon intensity, as observed in recent years, is expected to continue.

Gold-catalyzed intermolecular amination of allyl azides with ynamides: Efficient construction of 3-azabicyclo[3.1.0] scaffold

Chinese Chemical Letters 2025年第2期36卷 384-388页

作者： Chong-Yang Shi Jian-Xing Gong zhen Li Chao Shu Long-Wu Ye qing sun Bo Zhou Xin-Qi Zhu College of Chemistry and Chemical Engineering Yunnan Normal University Key Laboratory of Chemical Biology of Fujian Province State Key Laboratory of Physical Chemistry of Solid Surfacesand College of Chemistry and Chemical EngineeringXiamen University State Key Laboratory of Organometallic Chemistry Shanghai Institute of Organic ChemistryChinese Academy of Sciences Key Laboratory of Jiangxi Province for Persistent Pollutants Control and Resources Recycle Nanchang Hangkong University

Gold-catalyzed amination reactions based on azides via α-imino gold carbene intermediates have attracted extensive attention in the past decades because this methodology leads to the facile and efficient construction of synthetically useful N-containing molecules, especially valuable N-heterocycles. However,successful examples of intermolecular generation of α-imino gold carbenes by using azides as amination reagents are rarely explored probably due to the weak nucleophilicity of azides. Herein, we disclose an efficient gold-catalyzed intermolecular aminative cyclopropanation of ynamides with the allyl azides, enabling flexible synthesis of a wide range of valuable 3-azabicyclo[3.1.0]hex–2-ene derivatives in good to excellent yields with excellent diastereoselectivities. Importantly, this protocol represents the first use of allyl azide as an efficient amination reagent in gold-catalyzed alkyne amination reactions.

将轻工产业碳排放量作为非期望产出纳入全要素生产率模型,利用数据包络分析模型以及方向性距离函数,测算了2007—2016年我国轻工产业16个细分行业绿色全要素生产率增长情况,分析了轻工产业绿色生产率行业差异,并通过对轻工业绿色生产率的分解发现:全部行业和以农产品为原料与非农产品为原料两大类行业组技术效率指数总体上呈现出围绕着“1”上下波动的趋势,都经历了一个被拉伸的W型变动轨迹;技术进步指数走势线基本一致,均呈现出一条被拉伸的N型变动轨迹。还可以得到技术进步因素是轻工产业各行业绿色全要素生产率增长的主要驱动力,以农产品为原料轻工行业技术效率明显低于非农产品原料轻工行业,而农产品原料行业技术进步指数略高于非农产品原料行业。利用系统GMM等计量方法从轻工业细分行业角度对我国轻工产业绿色生产率增长以及分解项绿色技术效率、技术进步的影响因素进行实证检验,发现行业规模因素与轻工产业行业层面绿色生产率和技术效率负相关,与技术进步正相关,但是在统计学上都表现为不显著;禀赋结构因素对轻工业各行业绿色生产率增长及其分解项的影响是负向显著的;产权结构因素与轻工业行业层面绿色生产率及分解项显著正相关;能源结构因素对轻工业各行业绿色生产率以及分解项产生了显著的负面影响;研发水平因素对轻工产业绿色生产率及其分解项产生了显著的正向作用;外资规模因素对轻工业各行业绿色生产率以及分解项的影响是不显著的。

R. China School of Economy and Management Tianjin University of Science and Technology Tianjin 300222P.R.China Tianjin Municipal Committee of Development and Reform Tianjin 300040P.R.China

Low-carbon economic development has become *** approach to coordinating economic development and carbon emissions mitigation. As rapid developing economic, aviation and navigation, and financial center of North China. Tianjin＇s energy demand and CO2 emissions are mushrooming, with per capita CO2 emission from fossil fuel combustion exceeding 20 t in 2020, which much exceeds current level of USA. In the background of global responding to climate change, China will likely be requested to commit peaking its GHG emissions during 2020-2030, which will inevitable reduce the room of development in Tianjin enormously. Tianjin should make deployment ahead, realizing win-win of addressing climate change and sustainable development, with low-carbon economic development as important strategic mission. First of all, Tianjin should devote more efforts to reducing energy intensity and realizing relative emission reduction. Scenario analysis shows that Tianjin＇s future CO2 emissions will continue to increase rapidly, but they can be significantly reduced by taking measures. Second, Tianjin should get ready for achieving absolute reduction of CO2 emissions as soon as possible, preparing system, technology and talent in advance, making great efforts to establish institutional meehanisms conducive to low-carbon development from now on. starting from energy conservation and emission reduction, actively carrying out low-carbon technology research and development, vigorously developing the tertiary industry with low emissions, developing new and renewable energy resources, actively promote low-carbon consumption.

基于DEA-Malmquist指数测算省级区域绿色全要素生产率,运用莫兰指数定量分析其时空演化规律及其空间关联,借助信息透明度指数建立空间杜宾模型,实证检验信息透明度对绿色全要素生产率的空间溢出效应。结果表明在研究范围内中国绿色全要素生产率水平总体趋势稳定,存在一定波动。区域看绿色全要素生产率水平从高到低依次是东部、中部、西部,且绿色全要素生产率具有空间正相关性。信息透明和绿色全要素生产率之间存在空间非对称分布格局特征,信息透明度对绿色全要素生产率具有显著的空间溢出效应,提高信息透明度有利于中国绿色发展。最后针对中国当前绿色全要素生产率水平低、信息透明的溢出效应,提出相关政策建议以促进地区绿色、高质量发展。
