Energy Saving,Environmental Protection:Top Priority in China's Development——Exclusive interview with Dr.Yonglong L,Secretary-general,Chinese Committee for SCOPE(Scientific Committee on Problems of the Environment/ICSU).

Energy saving,emission reduction and economic development are major issues China has to meet in building a harmonious society.On one hand,China should pursue a sustainable,fast and sound economic development,on the other hand,she should try to decrease the overuse of energy resources and the environ- mental problems caused by the rapid economic growth. In this regard,on June 24,the Standing Committee of National People's Congress deliberated the draft of Energy Saving Law,according to which China is to take"resources saving"as a basic national policy.This is a key issue to the long-term benefits of China.With relevant questions,China's Foreign Trade interviewed Dr, Yonglong L(?),Secretary-general,Chinese Committee for SCOPE(Scientific Committee on Problems of the Environment/ICSU).and Research Professor at the Chinese Academy of Sciences. Let's listen to Dr.L(?)'s comments with wisdom.

Development of a Composite Eco-Material Based on Typha from a Clay Matrix

This work focuses on the design of a new type of eco-material based on Typha“Domingensis”and clay from the south of the Republic of Benin through various dosages.Three particle size classes of typha shavings were selected to be mixed with two types of clayin order to make parallelepiped shaped samples ready for experimentation.The massive use of these briquettes thus obtained,in the construction of habitats,would not only contribute to reducing the energy consumption inside the dwellings but also would limit the invasion of the waterways of Benin,which would facilitate navigation,fishing and river sanitation activities.In addition,this biosourced,low-polluting material would contribute to improving the energy transition by integrating it into rehabilitation of buildings.

财政分权视角下的地方政府多维效用函数与环保支出偏好

国内地方政府的环保支出偏好受制于特殊的财政分权架构,并会受到上级引导、同级竞争、本级财力等多重因素的制约,现有研究较少对财政分权架构下的地方政府的多维效用函数及由此引致的环保支出偏好特征展开讨论。为此,结合理论模型推导及涵盖2012—2019年247个地级市面板数据的实证检验,对财政分权架构下的地方政府环保支出的多元驱动机制作出诊断,结果发现:上级政策引导会激励地方政府的环保支出意愿,同级经济竞争和自身财力约束则会对其环保支出力度形成制约;多维约束间存在明显的交互效应,同级经济竞争与上级政策引导对地方政府的环保支出偏好存在显著反向对冲效应,而本级财力约束则会影响地方政府在上级引导与同级竞争压力间的权衡;本级财力约束会透过向上的财政依赖和内部财政支出腾挪两种不同的传导机制影响地方政府的环保支出偏好。因此,应构建兼容地方政府多维目标的综合方案,打造“考核竞争”的动态协同机制,设计适应地方财力约束的差异化路径,以有效解决地方政府环保支出激励问题。
