Huaibei is a typical coal resource-based city, the abundant coal resources lay a solid foundation for its economic development. Coal mining has induced a series of social problems, and affected the regional social and economic development. Ecological planning of Huaibei City concentrates on ecological restoration of coal mining subsidence, and applies circular economy to develop eco-agriculture, eco-tourism and eco-industry, which will contribute considerably to the economic transformation of the city. Analytic Hierarchy Process and mathematical statistical model were applied to calculate sustainable development indexes of Huaibei from 2002 to 2010. By evaluating the indexes, it was found that Huaibei City has a low sustainable development level, and 3 imbalanced subsystems as the major obstacle. The authors proposed countermeasures according to specific conditions of the city.展开更多

Furthermore, it makes current ways of reforming staffs' identity replacement and managers' shareholding mode inefficient in state-owned enterprises reformation in resource-based cities. According to the characteristics of resource-based cities and property right reform theory, cash and share right compensation for the different staffs in the process of staffs' identity replacement have been identified. In addition, different profitable investment policies have also been suggested. For managers' share holding, the stimulant share ownership should be adopted principally, at the same time corresponding restrictions should be set up for managers' investment share ownership due to share ownership structure.展开更多

Nineteen resource-based cities in Northeast China were analyzed using the indicator system. The results showed that Liaoning and Jilin provinces had higher economic resilience than Heilongjiang Province. Panjin, Benxi, and Anshan in Liaoning Province were the top three cities, while Shuangyashan and other coal-based cities in Heilongjiang Province ranked last. Metals-and petroleum-based cities had significantly higher resilience than coal-based cities. The differences in persistence, adaptability, transformation, and resilience among resource-based cities decreased since the introduction of the Northeast Revitalization Strategy in 2003. Forestry-based cities improved the most in terms of resilience, followed by metals-based and multiple-resource cities; however, resilience dropped for coal-based cities, and petroleum-based cities falling the most. The findings illustrate the importance and the way to develop a differentiated approach to improve resilience among resource-based cities.展开更多

This is because resource-based cities' economic development has fallen below general levels due to resource exhaustion and an unbalanced industrial structure, among other factors. Further, an economic gap has long existed between Northeast China's large number of resource-based cities and non-resource-based cities. This article comprehensively studies the economic convergence of Northeast China's resource-based cities and non-resource-based cities from 1996 to 2015 by using a dynamic panel to analyze not only the economic development of different industries and types of cities, but also the main factors that influence economic development. The empirical results demonstrate that economic convergence exists in both resource-based and non-resource-based cities, but the economic gap between them has clearly narrowed since the implementation of a strategy to revitalize the Northeast's old industrial base. Shrinking cities are the fastest to converge, as mature cities are slower and regenerating cities are the slowest; regarding industry structure, the secondary industry dominates the economy in mature and shrinking cities, and the tertiary industry in regenerating cities. The primary stimulus in resource-based cities' economic development involves upgrading the industrial structure and investing in human capital. As China faces a ‘new normal' economy, resource-based cities in Northeast China should restructure the economy and perfect their market system to avoid again widening the economic gap.展开更多

文摘The paper has proposed the design concept of "solid waterscape". It considers that in waterscape design, it should select a design style suitable for local climate, traditional culture and folk customs; respect the nature and be close to nature; and approach the life and fit in with the reality. In terms of flowing water and solid water, it should make a reasonable and comprehensive design in terms of time, space and pattern, develop new landscape factors, and enrich winter landscape; set indoor waterscape; and enrich color design. By taking waterscape design of the residential area "Riverbank House" for example, it has stressed the solid character of water to highlight snow and ice culture and northeastern style, so as to create a natural and vivid snowy and icy landscape. Snow and ice have been the lead of winter landscape. Finally, waterscape can provide two different patterns of beauty throughout the year.
