金融风暴中循环经济的一个悖论——论保护废旧物资回收利用体系政策

在华尔街金融风暴中,废旧物资回收利用链条一度陷于瘫痪,资源循环利用遭受阻断,循环经济发展受到严重影响。企业对再生资源利用选择水平与废品回收率的价格所存在的两难关系,决定了合理的价格水平和稳定的价格决定机制是关系到促进再生资源综合利用水平不断提高,循环经济顺利发展的必要条件。因此,政府需要进一步完善保护废旧物资回收利用体系政策,化解矛盾,促进循环经济发展。

Construction of Circular Economy Industrial System

Abstract

It is difficult to realize the transformation from traditional economy industrial system to circular economy industrial system. Regarding primary raw materials as the indicators, the industrial system has been specified according to the divergence among the indicators and the circular utilization modes. In comparison with the association among industrial systems, the relationship among industrial sub-systems is named as industrial cross-linking in this paper. The industrial system which could completely utilize and recycle the indicators should be increased and strengthened, and the circular economy industrial system with complete industrial association and industrial cross-linking should also be constructed. Taking the development of circular agricultural system basing on the traditional agricultural system as an example, the traditional agricultural products are regarded as the indicators which have been divided into foodstuff and crop straws which are used to produce food and articles for use, like fertilizer, energy and papers etc. The way to construct the circular agricultural industrial system is to increase the industrial systems that could utilize the products generated from crop straws, feces and other castoffs and transform the wastewater and other trucks into environmental friendly products. It has also been pointed out that the construction of circular economy industrial system is conducive to the foundation of circular industrial economics and the establishment of the construction layout of circular economy and the application schemes. Suggestions to the theoretical and practical work of the next step have also been brought forward in this paper.     

Study on the Circular Agriculture Development in Beijing’s Mountain Areas

Abstract

Circular agriculture is an essential way to realize the positive recycling of ecology and harmonious development of the country construction. The sustainable development of Beijing’s mountain areas depends on the background and orientation of ecological economy. Beijing’s mountain areas bear the responsibility of protecting the ecological safety of the whole Beijing district and also the exploration of circular agriculture in mountain areas is very important to promote the sustainable use of agriculture resources. Beijing’s mountain areas have possessed some practical experience in recycling agriculture development. Through summarizing the development mode and analyzing the development practice, the article puts forward three key segments of promoting Beijing circular agriculture development: strengthen propagate, develop superiority and built management mechanism.
