China‘s fast growing electrical vehicles leads to sharply rising used batteries, whose graded utilization needs to be industrialized, but its path and results are directly influenced by different technical directions. This paper, aiming at choosing appropriate investing direction and making matching policies, analyzes the key factors of industrial development from perspective of system based on practices, summarizes scales, costs, gains and profits under different technical directions by taking grid energy storage a scenario, and establishes a systematic dynamics model that is simulated for comparison. Two major technical directions, “decomposing-reconstructing” and “whole package utilization”, have their own pros and cons; however, “decomposing-reconstructing” direction prevails in expansion speed with no constraints of brands. Thanks to scale effect, “decomposing-reconstructing” direction beats the “whole package utilization” at the initial stage, but the latter will be gradually overcoming in a long term. Facilities cost and batter cost are the key factors, the former is falling while the latter is rising, facilities cost proportion has a faster/fluctuated falling compared to the “whole package utilization”, whose growing speed and gains will be largely improved if issues among different brands can be resolved and different EV makers can be united. This paper presents suggestions on selecting technical directions in accordance with national strategies, providing initial funds, offering matching allowance policies, promoting upper-to down-steam cooperation and implementing limited information sharing among different brands. 

This paper establishes a comprehensive index system to evaluate tourism and low-carbon city, uses AHP entropy to determine the weight of index to construct a coupling coordinated model of tourism and low-carbon city, and quantitatively analyzes its coupling process and trend of Huangshan’s tourism and low-carbon city from 2005-2014. The result shows a rising comprehensive tourism level and low-carbon city level with the exception of the year of 2013. The comprehensive tourism level from 2006-2012 is slightly higher than low-carbon city level. Their coupling coordination displays a consistent trend from three proportional contributions, indicating the proportion has little influence on coupling coordination. There is a rising coupling coordination between Huangshan’s tourism industry and low-carbon city with coordination types changing from disordered in 2005 to coordinated later and well coordinated in 2014. Huangshan city has a good basis for its development of tourism and low-carbon city at a fast rate; although fluctuated, it remains a sound developing trend. The administration’s supportive policies and tourism input will boost its tourism competitiveness along with its culture and ecology.

Unlike other industrialized countries, China's resource enterprises have to, too early, to face a series of issues derived from exhausted resources, which emerge before the completion of industrialization. These issues chiefly reflect on inherited burden, loss of core competitiveness and insufficiency of human resources because of a lagging regime reform, lack of technical innovation and weak industrial transformation. The dilemma from a unique historical reason needs efforts for enterprises in many aspects so as to achieve a sustainable development, in regime reform, industrial policies, social guarantee and industrial transformation and upgrade

Xuzhou, a typical resource-exhausted city with sole industrial structure, less economic growth point, and poor employment, is facing vast structural unemployment due to the exhausted resource. It is challenge that a labor transfer is unavoidable. This paper, based on a case study on Xuzhou, under the precondition of resource-exhausted city theory and surplus labor transfer mode theory, uses qualitative and quantitative method to analyze the feature of Xuzhous labor transfer, and presents approaches to a proper selection of surplus labor transfer mode, which guarantees a full employment for this transferred labors and promote a sustainable development in its economy.
