Empirical Study on Effect of Industrial Structure Change on Regional Economic Growth of Beijing-Tianjin-Hebei Metropolitan Region

Based on the data of gross domestic product(GDP),industrial added value and the proportion of industrial employees from 2000 to 2008,this paper studies the effect of industrial structure change on the regional economic growth of Beijing-Tianjin-Hebei Metropolitan Region in China using the shift-share method.The results show that:1) In the 21st century,the industrial output of three industries,namely,primary,secondary,and tertiary,and the GDP grew rapidly in the study period.The tertiary industry grew the fastest;it had the largest contribution to the GDP and mean-while had become the most competitive industry in the metropolitan region.2) The development of cities within the region was not balanced.Firstly,compared with Tianjin,Beijing,as one of the two core cities,was more rational in the industrial structure.Secondly,the surrounding eight cities,which are Shijiazhuang,Qinhuangdao,Tangshan,Langfang,Baoding,Cangzhou,Zhangjiakou,and Chengde,were all uncompetitive than the two core cities.3) There was a great industrial gradient in the region(especially between the two core cities and the cities of Tangshan,Baoding,Zhangjia-kou,Chengde,Cangzhou,and Langfang).As a result,it is foreseeable that the industry transfer in the Bei-jing-Tianjin-Hebei Metropolitan Region will be one of the trends in regional development,and the industry transfer is inevitably to promote the regional integration.

Analyzing the economic viability of a large-scale integrated model of municipal solid waste:a study case for the most important Brazilian economic region

Despite the National Policy for Solid Waste(PNRS)in 2010,nothing has changed to waste disposal in Brazil.Planned to reach 100%of all Municipal Solid Waste(MSW)collected and treated in landfills by Aug.2nd,2014,until nowadays,42%of this total remains in dumps.Even the most important national economic region treating its urban waste in landfills,what it has is no more than 4%of recycling and its landfills reaching the exhaustion.Building other ones is getting harder year by year,due to water reservoirs around the region,high freight costs,waste disposal and the severe control of emissions associated with its logistics.This article comes to break the paradigm of investment and profitability proposing an alternative to the land-use,achieving higher rates of recovering.The economic viability,carried out through well-known financial variables and Monte Carlo analysis,has taken into account proven local waste characteristics and market prices for recyclables and energy without subsidies.Even considered a proposal highly intensive in capital and people,the revenues from the sales would be enough to guarantee the viability of 100%equity with IRR of 33.7%and ROI of 24.5%per year within the confidence of 99%.
