In this study, remotely sensed images with approximately 30 m spatial resolution were used to quantitatively assess the spatial and temporal patterns of urban expansion of 60 Chinese cities(1973–2013). Urban-expansion-process curves of the cities studied were drawn using annual expansion area as an indicator. Curve similarity analysis generated four basic process modes of urban expansion in China. These included cities that: 1) peaked around 2004 and then decelerated; 2) peaked around 2010 and then decelerated; 3) showed sustained acceleration, and 4) showed continued deceleration. Four basic process modes represented cities under different levels of development stage. Geographic location was found to be the most related characteristic to urban expansion process. Regional development policies at the national level in each region also showed highly temporal consistency with fluctuation characteristics of urban expansion process. Urban characteristic such as population size and administrative level were not found to be significantly related to urban expansion-process modes. Understanding the basic process-mode categories well is extremely important for future regional-balance planning and development of macroeconomic policies.展开更多

However, leaves behind a huge material damage to the world economy and such crises remind national authorities of the mistakes done in the past while creating and running macroeconomic policy and teach them how they should overcome these crises in the upcoming period. The economic growth model of the selected South Eastern European （SEE） economies （Albania, Bosnia, Macedonia, Serbia, Slovenia, Croatia, Bulgaria, and Montenegro） during pre-global economic crisis was based mainly on foreign demand and capital inflows which created big external imbalances in those countries. It was the main reason why those countries were exposed to big vulnerability of external shocks. But, the crisis reshapes the world economic map. Competition on world markets gets new forms and players. The lessons learnt from economic crisis say that there is a need for revising the pre-crisis economic growth model in the selected countries as they are less vulnerable to external shocks. New economic model will enable their long-lasting and more sustainable economic growth in the future. One approach of remodeling their economy is presented in this paper. The main finding of this research is that instead of experiencing external ＂push＂ factors for economic growth by the governments, a promotion of internal resources is needed in order to enable ＂the catching up＂ process of these countries to continue. But, all those countries are members or candidates for becoming European Union （EU） members. That means there is no room for application on entirely new economy growth model, since those countries have to create economic model which has to be convergent to the EU one. There must be different approaches by individual countries in remodeling their economies. The findings of this survey are intended to remind the policy makers of the selected SEE countries of the mistakes they made before and during the economic crisis and the need and directions for remodeling their economies in the post-crises period that will enable their long-lasting and more sustainable economic growth in the future. The position assumed for this research is interpretative using qualitative methods of research. In order to ensure comparability among results, the proposed methodological design will be multiple-case study research on the selected SEE economies.展开更多

This paper discusses the theoretical origin of the circular economy, and clarifies the mechanism development of circular economy. Combined with the status quo of China＇s economic development, it analyzed the facing problems in the development of circular economy. Our country has carried on the positive exploration and practice in the use of the concept of circular economy to promote sustainable development, and China＇s circular economy is transferred from the start-up phase to promote the establishment of policy mechanisms. Circular economy strategy will also begin to implement in some of China＇s mega-cities. Faced with the arrival of the circular economy, we should look to a higher level up to explore how people should take effective measures to turn challenges into opportunities.展开更多

Treated as public policy since 2001, this mode of production and consumption has achieved increasing prominence on the world stage, its capacity for income generation and social inclusion. The program is developed from the parameters of the Municipal Social Assistance and Fellowship Economy and has the support of organizations such as the NGO （Non-Governmental Organization） Women in Motion, the Community Bank and SEBRAE. The research was based on survey data in the Registry, personal interview with the Superintendent of Solidary Economy. They still relied on data from the annual survey of the Department relating to the Network ECOSOL of 2007. This data allowed us to analyze the context of the movement, the target audience and the actions taken by the Department and effectively understand if the actions are having the desired results.展开更多
