Understanding Urban Vitality from the Economic and Human Activities Perspective:A Case Study of Chongqing,China

The literature on urban vitality tends to focus on the built environment.This paper argues that some important processes in shaping vitality may be overlooked without examining the intensity and diversity of economic and human activities.Using newly developed spatial big data and adopting the methods of multi-indicator measurement and spatial analysis methods,we analyzed the pattern of urban vitality in Chongqing,a provincial city in western China and,on this basis,evaluated the creation and maintenance of urban vitality from the economic and human activities perspective.Our findings indicate that the impacts of economic and human activities are positive and significant.Among the three intensity and diversity indicators,economic intensity and population density show an effect on urban vitality stronger than that of economic diversity.However,economic diversity has the strongest superposition or interactive effect,and is thus an important foundation dynamic.The positive effect of population density on urban vitality is largely a result of Chongqing’s jobs-housing balance.The case of Chongqing highlights the importance of topographic features,historical inheritance,large-scale migration,and cultural activities in shaping the distinctive vitality pattern of a city.This study contends that the creation and maintenance of urban vitality can not be fully explained without incorporating the impacts of economic and human activities.It contributes to a comprehensive measurement of urban vitality and enriches its connotations.

Analysis and Research on Industrial Land Transfer in Hefei City Economic and Technological Development Zone of Anhui Province

In recent years,with high-speed development of economy and society,and fast propulsion of industrialization and urbanization process in the development zone,average annual land demand in the development zone also quickly enlarges,and the contradiction between high-speed growth of economy and shortage of land resources is apparent increasingly. Meanwhile,to guarantee crop safety and stick to 0. 12 billion hm2of farmland red line as a rigid constraint which could not be exceeded,the supply-demand contradiction of industrial land is more and more prominent. With industrial land scale continues to enlarge,land resources become more and more scarce,but there exists the phenomenon of low-efficiency land use and even idle. For land use characteristics of the development zone,taking Hefei City Economic and Technological Development Zone as an example,the countermeasures of perfecting industrial land transfer mechanism in the development zone are proposed.

Spatial Pattern Evolution and Industrial Characteristics of Economic and Technological Development Zones and High-tech Industrial Zones in China

Economic and technological development zone and high-tech industrial zone are important types of development zone in China,and there are differences in their connotation and goal setting.In this paper,basic data of national and provincial economic and technological development zones and high-tech industrial zones in China were collected and arranged.Kernel density analysis and other GIS spatial analysis techniques were used to analyze the evolution laws of spatial patterns of economic and technological development zones and high-tech industrial zones in cities from 2006 to 2018.First,the agglomeration intensity was compared by measuring the degree of regional agglomeration and dispersion on the two time nodes.Next,kernel density method was used to explore the evolution of the two in the spatial layout and location,and analyze development commonness and difference of economic and technological development zones and high-tech industrial zones.Finally,the trend and reason of spatial evolution of development zones with different leading industries were explored.Research results show that:①the agglomeration degree of layout of high-tech industrial zones is stronger than that of economic and technological development zones,and there are similarities and differences in distribution trend of spatial patterns of the two types of development zones;②the distribution of labor-intensive,capital-intensive and technology-intensive development zones is concentrated at smaller scales and dispersed at larger ones;③although there are differences between the economic and technological development zones and the high-tech industrial zones in the goal,support,structure and function,management system and so on,their spatial development presents a trend of convergence.In the future,when enhancing urban-rural planning and public administration,governments should combine the trend of industrial transformation and upgrading,and optimize spatial layout of development zones by adjusting industrial structure,layout,transportation and land use.

Modeling of Combined Economic and Emission Dispatch Using Improved Sand Cat Optimization Algorithm

Combined Economic and Emission Dispatch(CEED)task forms multi-objective optimization problems to be resolved to minimize emission and fuel costs.The disadvantage of the conventional method is its incapability to avoid falling in local optimal,particularly when handling nonlinear and complex systems.Metaheuristics have recently received considerable attention due to their enhanced capacity to prevent local optimal solutions in addressing all the optimization problems as a black box.Therefore,this paper focuses on the design of an improved sand cat optimization algorithm based CEED(ISCOA-CEED)technique.The ISCOA-CEED technique majorly concen-trates on reducing fuel costs and the emission of generation units.Moreover,the presented ISCOA-CEED technique transforms the equality constraints of the CEED issue into inequality constraints.Besides,the improved sand cat optimization algorithm(ISCOA)is derived from the integration of tra-ditional SCOA with the Levy Flight(LF)concept.At last,the ISCOA-CEED technique is applied to solve a series of 6 and 11 generators in the CEED issue.The experimental validation of the ISCOA-CEED technique ensured the enhanced performance of the presented ISCOA-CEED technique over other recent approaches.

Trumponomics and China-US Economic and Trade Relations

Since he took office, the new US president, Donald Trump, has unveiled his broad economic policy--now called Trumponomics. It emphasizes neoliberalism at home, less government regulations, more growth and weakening the welfare state. Intemationally, Trumponomics embraces protectionism and nativism with a focus on US economic interests. Trumponomics caters to the lower-middle classes, a reflection of the country＇s current economic and diplomatic challenges. Trumponomics will bring uncertainty to China-US economic and trade relations. China should carefully study the policies of the Trump administration and prepare contingency plans.

Economic and Financial Viability in Spanish Thermal Power Station

This article tracked, identified, and demonstrated the economic and financial viability of the renewable energy sector from biomass in a Spanish Thermal Power Plant. The methodology used came from Theoretical postulates （GITMAN, 2004; VAN HORNE, 1993） called, Technical Preparation of capital budgets （Economic and Financial Analysis） called, payback, Net Present Value, and Internal Rate of Return）. The economic and financial viability results demonstrated were in two stages： the first identified that the plant is viable according to the payback. The second traced the economic and financial viability from the thermal energy production hypothesis equivalent to electricity power in the amount of 7,699.08 MWh, which resulted in the following indicators： payback of seven years and three months, NPV of R$ 369,064.98, and the IRR of 12.46%. Therefore, managers would have to make a user raising campaign in the ratio of 24.66%, taking into account of an unused capacity of 25%. These indicators were calculated using the following financial data： initial investment of R $ 3,654,731.86, operational income of R $1,262,264.16, operational inputs of R$ 503,639.59, and capital cost of 10.95% over 20 years. This industrial plant is located in the city of Cuellar in northern Spain, having two employees working eight hours a day; it produces only thermal power, represented in this study by MWh of electric power. This industrial plant produces power by burning forest residues from tree pruning. It was concluded that, given the research question developed in this paper--is the study plant profitable from the economic and financial point of view？--The response was identified by calculating the economic and financial indicators that the plant studied is viable from the proposed of maximizing sales revenues to 7,699.08 MWh.
