Industrial Cluster Upgradation of Regenerated Resources in Miluo City

With China's rapid economic growth, ecological construction and environmental protection become increasingly important. The regenerated resources industry is an effective way to solve problems, such as resources depletion, energy shortage, and pollution, and it also has strategic importance for the construction of a resource-conserving and environment-friendly society. The regenerated resources industry has been established in Miluo for long time, which includes a recycling system, a processing and utilization system, and a refuse decontamination system. An industrial cluster is in its early stage of development. In order to solve current problems, such as short industrial chain, low processing rate, and low added value, the industrial cluster should be dynamically upgraded by means of technology innovation, chain nucleus creation, and chain extension. We think the industrial cluster of regenerated resources will become a local brand for Miluo, from which other regions or cities will gain valuable experiences and inspirations.

Towards a smallholder hydrology for equitable and sustainable water management

Situations of water scarcity challenge sustainability and threaten small users' access to water. In response to this problem, there has been a search for a method of hydrological analysis that can better represent the needs of small water users. While this search is rooted in the debate favouring a more participatory and inclusive allocation of the resource, it also requires a new focus on smallholder hydrology that can confront the gaps and biases found in current hydrological practices in many countries. This article looks at past hydrological practices and also at results of recent studies, highlighting the perspective of smallholder irrigators in surface water planning in Zimbabwe, and groundwater planning in India. These case studies show that wider social forces, not always best science, drive hydrological practices. However, new frameworks focusing on the water user can emerge for more equitable and sustainable water management.     

人口流动规律及其政策含义

人口流动是人力资源配轩优化的根本创新路径,人口流动的一般规律是:如果流动人口为理性行为选择者,在社会制度安排许可的发展环境下,当不同区域和不同产业间形成比较收益差异,存在着流动收益大于流动成本的潜在和现实的各种获利机会时,就必定驱使人们由低收益领域向高必益领域流动,而且比较收益差异量与流动人口的流速、流量正相关,并必然导致产生收益率及人口分布走向平均化的趋势,社会发展也将获得最优化的人力资源配置结果.其相关政策含义:一是人口流动是流动人口的理性选择;二是切实保障公民的自由流动权利;三是利用比较利益差别促进人口流动;四是降低各种不必要的流动成本和流动风险;五是建构人口流动的有效率社会发展框架.     

中国经济的“阿基米德支点”

资源是经济发展的“阿基米德支点”：世界十大经济国每年能源的生产占全球的６２．１％，消费为７１．０％。重要矿产资源的生产多排在世界前１０名生产国之，外面是消费则多排在１０名之内，且对这些矿产资源的消费量多在９５％以上。     

我国矿产资源态势与对策

我国矿产资源总量大,居世界第3位人均拥有量小,居世界第80位。我国要实现现代化建设的第二步战略目标,矿产资源供需存在着矛盾。为了解决供需矛盾,必须从地质找矿、矿山、一次资源回收、二次资源回收、节能和节材等方面挖掘潜力。改革资源耗费型经济发展旧模式,确立资源节约型经济发展新模式,废止“有水快流”的方针,确立开发与节约并重的方针,是缓解矿产资源供需矛盾的根本途径。具体对策有:(1)依靠科学技术进步开发节约(2)搞好资源进出口贸易取长补短(3)健全法制管理体系依法治矿(4)用好计划机制管好资源和矿山(5)用好市场机制搞活矿业经济。     

The evolution of sustainability

Six separate but related strains of thought have emerged prominently since 1950 in discussions of such phenomena as the interrelationships among rates of population growth, resource use, and pressure on the environment. They are the ecological/carrying capacity root, the resources/environment root, the biosphere root, the critique of technology root, the no growth/slow growth root, and the ecodevelopment root.Each of these strains of thought was fully developed before the word sustainable itself was used. Many of the roots are based on fundamentally opposing assessments of the future of mankind. Many of the roots, such as the ecology/carrying capacity root, are based on physical concepts, and they exclude normative values. Others, such as the ecodevelopment root, include such values as equity, broad participation in governance, and decentralized government.When the word sustainability was first used in 1972 in the context of man's future, in a British book,Blueprint for Survival, normative concepts were prominent. This continued to be the case when the word was first used in 1974 in the United States to justify a no growth economy.Sustainability was first used in a United Nations document in 1978. Normative concepts, encapsulated in the term ecodevelopment, were prominent in the United Nations publications.After about 1978, the term sustainability began to be used not only in technological articles and reports but also in policy documents culminating in the use of the term in the report of the summit meeting of the Group of Seven in 1989.The roots of the term sustainability are so deeply embedded in fundamentally different concepts, each of which has valid claims to validity, that a search for a single definition seems futile. The existence of multiple meaning is tolerable if each analyst describes clearly what he means by sustainability.     

中国跨境能源贸易及隐含能源流动对比——以“一带一路”能源合作为例

随着“一带一路”倡议的提出,能源互联互通成为中国对外合作的重要组成。以“一带一路”能源合作为切入点,从直接能源贸易和隐含能源流动的双重角度刻画中国跨境能源关联并开展对比研究,主要结论包括：（1）从直接能源角度,“一带一路”沿线沙特阿拉伯、俄罗斯等国家均为中国重要的直接能源进口国;（2）从隐含能源角度,中国为印度、新加坡、泰国等国家提供了大量的能源相关的商品服务;（3）中国与“一带一路”沿线国家直接能源贸易逆差明显,但隐含能源流动处于顺差地位;（4）综合考虑直接能源贸易及隐含能源流动,中国可以发挥不同类型能源关联的辐射带动作用,为中国与“一带一路”沿线国家能源互联互通与共建合作伙伴关系提供坚实基础。

中国“四化”建设对水足迹强度的影响分析

采用2000—2016年中国30省市（不包括香港、澳门、台湾、西藏四省区）的数据,构建四化指标体系,计算四化发展指数,进行地区四化水平评价,通过OLS和GMM回归模型考察四化发展对水足迹强度的影响,同时设置四化之间的交互项来识别四化指标之间的相互作用。主要结论如下：首先,从四化水平的地域发展差异上来看,中国四化水平总体上呈现出东部优于中部、中部优于西部的格局,水足迹强度的分布与之类似,说明四化水平发展与水足迹强度之间可能存在相关关系;其次,计量模型显示四化水平的提升对于水足迹强度的改善有积极影响,但每一化对于水足迹强度改善的影响大小不一;第三,以交互项衡量的四化相互作用对于水足迹强度的影响作用为正,表明四化发展对水足迹强度的改善效果逐渐趋于收敛。因此,优先提升落后地区的四化水平,以四化水平的提升推动水足迹强度的降低,能够有效降低我国总体水足迹强度水平。
