Our research indicates that carbon emission intensity from industrial structures in the Xuzhou Metropolitan Area at first showed an increasing trend, which then decreased. Furthermore, the relationship between emissions and industrial economic growth has been trending toward absolute decoupling. From the perspective of the center-periphery, the Xuzhou Metropolitan Area formed a concentric pattern, where both progress towards low emissions and the level of technological advancement gradually diminished from the center to the periphery. In terms of variation across provinces, the ISCB index in the eastern Henan has decreased the slowest, followed by the southern Shandong and the northern Anhui, with the northern Jiangsu ranking last. During this period, resource-and labor-intensive industries were the primary growth industries in the northern Anhui and the eastern Henan, while labor-intensive industries dominated the southern Shandong and capital-intensive industries dominated the northern Jiangsu. In terms of city types, the spatial pattern for industrial structure indicates that recession resource-based cities had higher carbon emission intensities than mature resource-based cities, followed by non-resource-based cities and regenerative resource-based cities. Generally, the industrial structure in the Xuzhou Metropolitan Area has transformed from being resource-intensive to capital-intensive, and has been trending toward technology-intensive as resource availability has been exploited to exhaustion and then been regenerated. Industrial structure has been the leading factor causing heterogeneity of carbon emission intensities between metropolitan cities. Therefore, the key to optimizing the industrial structure and layout of metropolitan areas is to promote industrial structure transformation and improve the system controlling collaborative industrial development between cities.展开更多

Research findings suggest that: RMB depreciation will drive employment and wage growth for most of China's laborintensive manufacturing sectors, and RMB appreciation will increase employment for certain capital-and technology-intensive sectors; but RMB depreciation has insignificant employment and wage effects for most sectors in the US. Hence, in achieving the longterm stability of RMB exchange rate, China should take advantage of RMB appreciation's manufacturing upgrade effect and ensure the steady growth of manufacturing employment.The US should make breakthroughs in various links of its economic development in order to tackle unemployment, instead of blaming RMB exchange rate. In addition, the nature of business activities and trade union characteristic are both significant factors that lead to differences in inter-sector employment levels of Chinese and US manufacturing sectors.Technology characteristic and other monopolistic characteristics exert decisive effects on the difference of wage return for various sectors in China and the US.展开更多

Using the industrial structure characteristic bias index and data from 29 manufacturing industries in each province from 1995 to 2010, we described the impact of pollution-emission characteristics of industry structure on the regional environment. The results show that wastewater-discharged characteristic of industrial structure in the northwest and central areas declined from 1995-2010, but this trend has weakened. The industrial structure of southwest and southeast areas had a high level of solid waste discharge and a constantly strengthening trend in SO2 emissions. We also analyzed the growth and recession of each sector in eight regions in China from 1995 to 2010. Among the eight regions, the middle reach of the Yel ow River, and northwest and southwest China had a clear increasing trend of high pol ution industries;the eastern coast, southern coast, middle reach of the Yangtze River and northeastern China did not sustain an increase in high pollution industries. In addition, regression analysis modeling was used to analyze the impact of the evolution of industrial structure on the disparities of regional environmental effects. We found that regional industry structure was closely related to environmental quality, especially for western areas at lower stages of economic development. In the future, all regions must prevent and forefend the risk of environmental pollution in the update and adjustment of industrial structure.展开更多

In this paper, comprehensive assessment indicators for re- gional economic development and environmental pollution subsystems are constructed. Then the degree of coupling and coordination of the regional economy-environment system is calculated for 350 prefectural units in China. It is found that the economic development and environmental pollution in most prefectural units is still at a low level of coupling and coordi- nation. According to the coupling and coordination values, the Chinese territory can be di- vided into four types of area： economy-environment harmonious area, economy-environ- ment gearing area, economy-environment rivaling area and low coupling degree of econ- omy-environment area. Based on a structural analysis of the industrial sector in the four types of areas, there is a spatial relationship between the regional industrial sector structure and the coupling-coordination level. In the economy-environment harmonious area, the sectors of manufacturing of high-technology and high value-added products, such as com- munications, computer and electronic equipment, transport equipment and electrical ma- chinery, account for a large proportion of the value of local industrial output. The industrial value of the economy-environment gearing area is concentrated on the manufacturing of machinery and equipment, and. contains a few polluting sectors such as ferrous and non-ferrous metallurgy, chemical manufacturing and electricity generation. The econ- omy-environment rivaling area is the type of area where polluting sectors concentrate, such as iron and steel, petrifaction, coal mining, building materials and electricity generation. In the low coupling degree of economy-environment area, its industry is concentrated on the pro- duction and processing of primary products.展开更多

文摘Given the great number of studies focusing on the temporal interaction between economic and environmental subsystems, it is useful to perform a quantitative spatial as- sessment of these subsystems. In this paper, comprehensive assessment indicators for re- gional economic development and environmental pollution subsystems are constructed. Then the degree of coupling and coordination of the regional economy-environment system is calculated for 350 prefectural units in China. It is found that the economic development and environmental pollution in most prefectural units is still at a low level of coupling and coordi- nation. According to the coupling and coordination values, the Chinese territory can be di- vided into four types of area： economy-environment harmonious area, economy-environ- ment gearing area, economy-environment rivaling area and low coupling degree of econ- omy-environment area. Based on a structural analysis of the industrial sector in the four types of areas, there is a spatial relationship between the regional industrial sector structure and the coupling-coordination level. In the economy-environment harmonious area, the sectors of manufacturing of high-technology and high value-added products, such as com- munications, computer and electronic equipment, transport equipment and electrical ma- chinery, account for a large proportion of the value of local industrial output. The industrial value of the economy-environment gearing area is concentrated on the manufacturing of machinery and equipment, and. contains a few polluting sectors such as ferrous and non-ferrous metallurgy, chemical manufacturing and electricity generation. The econ- omy-environment rivaling area is the type of area where polluting sectors concentrate, such as iron and steel, petrifaction, coal mining, building materials and electricity generation. In the low coupling degree of economy-environment area, its industry is concentrated on the pro- duction and processing of primary products.
