To evaluate the key factors of Tianjin's oceanic resources environmental carrying capacity, this paper selects 27 indicators among oceanic resource system, oceanic environmental system and social economy system to establish an evaluation index system of oceanic resources environmental carrying capacity, with entropy-weighted TOPSIS model applied to evaluate Tianjin's oceanic resources environmental carrying capacity during 2007 to 2016 and its three sub-systems, key factors identified with gray correlation coefficient. In the period of 2007 to 2016, Tianjin's oceanic resources environmental carrying capacity amounts to 0.3412 to 0.5664, an intermediate level, showing a developing trend of descending-stabilizing-rising-stabiliing, descending during 2007 to 2010, stabilizing during 2010 to 2012, rising conspicuously during 2012 to 2014, and gradually stabilizing during 2014 to 2016. Tianjin's oceanic resources carrying capacity has a little change, its oceanic environmental carrying capacity shows a “V-shaped” trend and its social economic carrying capacity has a “W-shaped” trend. Gray correlation coefficient calculation indicates that key factors are annual sulfur dioxide and pollution control investment to GDP. This paper presents suggestions on rationally developing oceanic resources and developing coastal tourism aiming at improving Tianjin's oceanic resources environmental carrying capacity.

This paper establishes a dynamically optimized model of sustainable development for Hebei's water resource, water environment and social economy based on input/output table, and uses LINGO software to simulate the economic growth in different scenarios under dual constraints of water resource and environment. In the case of optimized scenario (comprehensive scenario), industrial adjustment, fiscal allowance for recycling water and southwaternorthtransfer, introduction of waste water processing technology can promote the sustainable development of Hebei's water resource, environment and economy. COD emission will be reduced by 10% in 2025 compared to the year of 2015. Economic growth rate will be 7.51% annually from 2007 to 2025. Industrial structure will be optimized to 12∶32∶54 in 2025 among the three industries. Water use in agriculture, industry, living and landscaping will be optimized to 59%, 21%, 12% and 8%. Underground water, surface water, recycling water and input water will be optimized to 63%, 16%, 7% and 13%. Hebei provincial government will provide fiscal allowance 7.813 billion RMB in water resource supply, of which 5.225 in newlyconstructed waste water plants, and 2.588 in recycling water piping.

In order to mitigate the shortage of water resources in Beijing-Tianjin-Hebei area, government attempts to change the traditional decentralized water resource allocation model into a unified platform. This paper, by making a detailed social accounting matrix of water production and supply in Beijing-Tianjin-Hebei, uses multiplier analysis and structured path analysis to compare their economic influence and path changes if water production and supply changes. After unified allocation, Beijing's driving force of water production and supply is declining, but there is a rise in capital circulation proportion; Tianjin and Hebei's driving force is rising with an increasing linkage in production departments, and Tianjin's residents' capital income also rises. That means the unified mode has a positive influence on Beijing-Tianjin-Hebei's water industry. This paper suggests establishing and optimizing trans-region water resource allocation mechanism in Beijing-Tianjin-Hebei for a co-integrated development.

BeijingTianjinHebei located in the Northern China is seriously short of water that the water supply is less than the half of demand. Agricultural water mounts up to 70%, and in rising. A rational allocation of water use can help the sustainable development in this area. This paper by using the virtual water algorithm measures their virtual water of ten agricultural products and establishes a fixed effect regress model to analyze its influence on economy. Adjusting agricultural structure can reach the objective of saving water and promoting sustainable development of economy. In 2014 the virtual water of agriculture is 10 times the actual water use, 1854×1010m3. Their annual virtual water in ten agricultural products rank in order, grain crops, poultry eggs, forest products, meat, dry and fresh fruit, milk, vegetables, fishing products, oil products and cotton. It could save 32×108m3 every year under an open system through adjusting agricultural structure and virtual water trade.

China's urbanizationlevel is rising withenergy consumption. Short of energy, energy security and carbon emission demand to consider the influence of urbanization on China's energy consumption and economic development. This paper, based on China's input & output 2007, uses social audit matrix and static CGE model to simulate the influence that urbanization has a strong positive pull to macroscopic economy, and leads to a rising energy demand influenced by income effect, increasing energy investment from substitutioneffect, ascending energy price, improving residents' welfares with urban residents better than ruralones.

This paper, based on Henans 2007 and 2010 input/output data, establishes input/output model to calculate Henan coal industry coefficient, which is used to analyze the correlation effect of Henans coal industry. The result displays a high correlation with other industries, indicating coal industry is an intermedium product industry. Coal industrial development is a strong drive to other industries, also needs others support. Henan can promote upgrading and optimizing industrial structure through adjusting coal department, developing upperand downstream industries and improving industrial chain.

Mining economic zone is a vital carrier in promoting resources to be rationally allocated and sustainable development of mining economy. This paper, based on the concept of mining economic zone, uses AHP which is given weight by grey correlation to analyze Anhui's 6 mining economic zones in their regional competitiveness from economic strength, industrial benefits, openness and concentration capability, labor, infrastructure, scientific and educational capability and resources environment, with ranking, downwards, Maanshan iron mining economic zones,TonglingFanchang Nonferrous, Huainan CoalCoal Chemicals, Huaibei CoalCoal Chemicals, Lujiang mining economic zones, Huoqiu iron ore mining economic zones. The former four belong to maturedeclining zones, while latter two to developing zones.

This paper,based on the definition of adaptability of industrial ecological system in mining zones,uses vulnerability,sensitivity,stability and elasticity to establish an index system to evaluate the adapt ability of Huoqiu in 2008 to 2012 by means of a hierarchical AHP and entropy is used to give weight of each index,combined with a levelled evaluation.The results show Huoqiu’s adaptability climbs to 0.1756 from 0.1585,indicating a rising adaptability and a descending vulnerability.Among Huoqiu’s industries,resources and environment system’s adaptability rose largely,but with a higher sensitivity,strong vulnerability and poor stability.This paper gives proposals to enhance Huoqiu’s adaptability of industrial ecological system.
