Realizing ecological product values is a key part of China’s ecological civilization construction, and a necessity for China to make policy and manage natural resources. This paper gives definition of conceptual content of ecological products according to realization need of ecological product values, and establishes a system margin of ecological product values, in which the basis of realizing ecological product values is discussed from ecological system, ecological product value constitution, ecological product accounting and balancing. Life circle rule is used to build the approaches to ecological product values, including unit processes of ecological system, ecological products, accounting, balancing, producing, trading and consuming. Alternative approaches involve three key steps, producing, trading and consuming. Selection of them is actually to define the trading ways and to turn products into consumer goods. The core in producing stage is supplier and supplying means of productive elements, the key in consuming stage is payer who is related to consuming category of ecological products. Analysis and summary of approaches to different ecological systems and realization of ecological product values provides references for the innovation of realizing ecological product values.

To improve theoretical research and practical summary of renewable resources recycling and to resolve environmental impacts of recycling resource dumping on surface so as to develop ecological economy and boost renewable resource industry, this paper reviews the theoretical research and practical progress from basic theory, reverse logistics of renewable resources and recycling practice. Scholars worldwide carry out theoretical research on economic evaluation, potentials, reverse logistics of mineral resources, and elaborates practices on China's policies and industrial evolution, and analyzes the revelation of America, Japan and Germany on renewable resources recycling, and presents approaches to China's developing renewable resources industry.

This paper, based on a case study on Shanxi-Shaanxi-Inner Mongolia (JSM) energy concentrating area, establishes an input output model which is used to study its hidden carbon emission transfer in their trading, calculates their carbon emission transfer volume in each province to other regions and their mutual transfer volume, aiming at offering reference for clarifying responsibilities in carbon emission reduction. The transferred carbon dioxide volume from other regions to JSM is higher than that from JSM to other regions, meaning JSM partially bears carbon emission pressure from other regions, mostly concentrating on coal mining and beneficiation, petroleum, coking and nuclear fuel processing. Inside JSM, their transferred volumes relatively close. JSM provides large quantity of high-energy-consuming and high-carbon-emission products to other regions by means of its abundant energy resources, and can provide energy consumption for itself, only needing a few from outside to satisfy the diversity. This paper suggests making regional collaborative emission reduction policy and taking reasonable responsibilities in order to promote low carbon development.

This paper, based onnine factors relatedto energy supply stability and Shaanxi'sdata 1990—2011, concludes that the major factors of Shaanxi's energy supply stability are energy investment, carbon emission intensity, GDPper capita, industrial structure, population with their elasticity 0.8293, -0.2373, -0.2876, -2.1336and -2.4144, respectively. According to Shaanxi'senergy objectives and economicsocial planning, thispaper sets up scenarios for economy,popular growth, carbon emissionintensity andenergyinvestment, and forecasts the stability under ninescenarios. Shaanxi's stability rises upto 5.567 1 in 2020 under a low growth of populationand GDP per capita, a high growth in energy investment, andan intensified industrial structureadjustment and reducing carbon emission, but can't last long. Scenarios A, Band C are assumed under different energy investment growth to study the influence ofenergy investment over energy supply stability,which need tolimit growth in energy investment to avoid over mining and to maintain a rational energy production.

This paper, based on GDP per capita from 2000-2010, uses standard deviation, variation coefficient to describe the temporal features and uses deviation, ratio and relative development speed to describe the spatial features of the economy of Xinjiangs 14 regions. The reasons for regional economic disparity in Xinjiang are analyzed, and the approaches to promoting regional economic development are presented. The economy in Karamay is more developed than other regions. The development level is middle in Urumqi, Changji, Turpan and Bayinggol, but low in other regions, which is connected with natural environment, location, transportation, policy, industrial structure and population. This paper suggests enhancing governmental controls, optimizing regional industrial structure, controlling population, enhancing population quality and boosting Xinjiangs coordinated development.

Abundant mineral resources could promote regional economic growth. However irrational exploitation of mineral resources may bring about various environmental, economic, social problems. This paper analyzes the adverse effects of the exploitation of mineral resources on environment, economy and society, with some practical examples of China’s western regions, and makes suggestions on how to escape the detrimental impacts. The solutions that are given include achieving sustainable development, promoting green mining, considering the benefits of the majority of local residuals, enhancing international exchanges and other related measures.
