Unit Environmental Property Rights: Efficiency, Responsibility and System

The inexplicit efficiency of environmental property rights lies in its fuzziness. Based on the character of environmental property rights discussed, unit environment shows intra relationship between efficiency and duty of environmental property rights, and constructs a symmetrical system arrangement. Through analyzing the possibility and feasibility of unit environmental property rights, the significance of symmetrical system arrangement to avoid the inexplicit efficiency of environmental property rights is discussed in this dissertation from the aspect of the validity of offering and implementing system.

Economical Analysis and Optimization of Recovery Processing Policies about Discarded Product

On the foundation of analyzing the closed loop logistics chain of product with multi-lifecycle, the connotation of environmental value is set forth, recurring to such conceptions as supply chain and value chain. The plotting rules about disassembly tree are discussed in detail. The reachable matrix R of components’ disas- sembly is introduced into distinguishing if disassembly is needed, in combination with disassembly-deciding vector X. Furthermore, the arithmetic of disassembly cost is put forward. And the cost-benefits of components’ reusing, materials’ recycling, safety disposing are dissertated based on the activity-based costing. Then the 0-1 goal-programming model on product recovery processing is established, with components’ demotion calculated. In addition, taking the PC’s recovery processing for example, we put it into application.

Scenario Formation of Energy Demand and CO_2 Emissionsfor Sustainable China

Co-integration theory has been employed in this paper and Granger causes are found between urbanization rate and GDP, between capital stock and GDP. Scenario analysis of GDP is performed using the GDP model established in the paper. The energy consumptions in Germany, Japan and other developed countries are analyzed and compared with the energy consumption in China. Environmental friendly scenario of energy demand and CO2 emissions for sustainable China has been formed based on the results of comparison. Under environmental friendly scenario, the primary energy consumption will be 4.31 billion ton coal equivalence （tee） and CO2 emissions will be 1.854 billion t-c in 2050; energy per capital will be 3.06 tee that is 1.8 times of energy consumed in 2005 in China and 51% of consumed energy per capital in Japan in 2003. In 2050, the energy requirement of unit GDP will be 20% lower than that of Germany in 2003, but will be still 37% higher than that in Japan in 2003. It is certain that to fulfill the environmental friendly Scenario of energy demand and CO2 emissions is a difficult task and it needs long term efforts of the whole society, not only in production sectors but also in service and household sectors,

Environmental protection versus economic growth

This paper presents and analyses the differences in the eco-models implemented worldwide （such as whether and how carbon taxes being ＂recycled＂）, or in their efficiency parameters （inconsistent parameter values that account for different results）. This is the assumption that a real tradeoff exists between the production of environmental goods. The present article empirically proves that something must be given up in order to gain something else, and once equations are specified to trace out the path of the economy over time, the natural economic formulation of such equations will embody the notion of economic and bio-tradeoffs.

A model of techno-economic evaluation for eco-industrial park project

An eco-industrial park or estate is a community of manufactaring and service businesses located together on a common property. The goat of ElP is to create a win-win harmonious development aspect of ecooomic development and environmental protection. This paper emphasizes that the external .effect of an EIP is its main characteristic of technoeconomic evaluation for eco-industrial park project. From the view of the property, rights, the EIP＇s product is typicalty public-private. The government should take some inca.rares for the quantitative analysis on ecological positive externalities of the enterprises in EIP, and also should adopt Coase＇s Theorem, which supports that the market transaction is the best way to deal with positive externalities （external economics or diseconoraics）, or Pigou＇s Theorem, which holds that the government anti-positive externalities programs are the best way to cope with positive externalities, to internalize the EIP＇s external effects, which is also a fundamental tool to encourage investors to actively invest in EIP projects, Furthermore. this paper thinks that the EIP ＇s income should be equal to the income of staple products of the private property, and that of its by-products of the public property. According to this principle, this paper has put forward three major indicators, net present value （NPV）, internal rate of renan （IRR）, and investment repayment period （IRP）, which are also extensively used indicators in ardinary project techno-economic evaluation model to evaluate EIP technoeconomic effects. Theoretically, the indicatory not only can be used in EIP project evaluation, but also can provide a quantitative measure toot for the government to support EIP＇s construction to the maximum. In the end. a case is analyzed.

Based on the Incentive Mechanism of Enterprise Reverse Logistics Research Literature Review

In recent years, along with the people environmental protection consciousness enhancement and the concept of circular economy enterprises to implement reverse logistics is imperative. In recent years, based on the incentive mechanism of reverse logistics literature has gradually emerged. In this paper, the concept of reverse logistics are introduced in detail, and compares the forward logistics and reverse logistics, analyzes the driving factor for the formation of reverse logistics, from the Angle of the government and the enterprise two introduces the related literature, the incentive mechanism on the basis of the summary, summarized the problems of enterprise reverse, government incentives for enterprises is discussed the importance of reverse logistics, based on the existing research results in recent years to sum up, the paper further research are pointed out.

Approach to the Legislative Problem of the Recycling Economy in Kunming

This paper takes Kunming as an example, analyzes the reasons and advantages that Kunming badty needs to make local laws and regulations of recycling economy. Initiation and assist of the government and formulation of the corresponding laws and regulations are issues deserved to pay close attention to. Some plain suggestions for the local legislation of recycling economy are put forward.
