  • land use balance for Urban Economy a multi scale and multi type perspective
    Land Use Policy, 2019
    Co-Authors: Mengyao Han, G Q Chen, Michael Dunford
    Abstract:

    Abstract In a situation in which land is in short supply, attention has focused largely on the direct use rather than on the indirect use of land embodied in regional, national and international flows of goods and services. To fill this gap, the multi-scale input-output method is used to identify the impact of final demand and trade activities on the requirements of a single metropolis, Beijing as a case, for land use embodied in its supply chains and commodity trade. While Beijing has limited land at its disposition, the land embodied in its final demand exceeds its own land area by a factor of more than ten, indicating the importance of co-ordinated land use planning and of supporting assessments of land use balance. Covering both direct and indirect land utilization through supply chains, the multi-scale land use analysis plays a significant role to extend the Urban land use planning to different scales’ sources and sinks. It is thus essential to identify land use balance at Urban Economy, which could provide potential policy implications for dynamic adjustments of land use allocation and land-intensive industries from a multi-scale and multi-type perspective.

  • Urban Economy s carbon flow through external trade spatial temporal evolution for macao
    Energy Policy, 2017
    Co-Authors: Bin Chen, Qing Yang, Sili Zhou, G Q Chen
    Abstract:

    Abstract A typical heterotrophic Urban Economy relies heavily on external trade, which inevitably generates carbon emissions outside its administrative boundary. Based on the most updated multi-regional input-output table, this study investigates the evolution of energy-related carbon flows embodied in Macao's external trade. The results show that both carbon inflows and outflows maintain a growing trend from 2000 to 2013 in general, accompanied with some rise and falls during this period. Total carbon imports increase from 3.67E+06 t in 2000 to 1.24E+07 t in 2013, whose main contributor changes from Sector Textiles and Wearing Apparel in 2000 to Sector Electricity, Gas and Water in 2013. Mainland China, the European Union and Japan are the main providers of carbon inflows. Dominated by gaming service exports, total carbon outflows are equal to 6.48E+06 t in 2013, which is 2.6 times that of year 2000. Macao has avoided large amounts of local carbon emissions by net carbon emission imports, indicating that the decarbonization of the Urban Economy achieved by transferring carbon intensive industries to other places is a bias towards sustainability. Following the results, holistic energy conservation and carbon reduction policies are proposed for Macao from both the local and global perspective.

  • embodied water for Urban Economy a three scale input output analysis for beijing 2010
    Ecological Modelling, 2015
    Co-Authors: Mengyao Han, Ling Shao, M. T. Mustafa, Tasawar Hayat, G Q Chen, X.h. Xia
    Abstract:

    Abstract The scheme of a three-scale input–output analysis is presented in this study to investigate the water use profile of the Urban Economy in Beijing. Defined as total water including direct and indirect water, embodied water for an Urban Economy supported by massive domestic and foreign trade can be decomposed into nine categories corresponding to three sources (local withdrawal, domestic imports, and foreign imports) and three destinations (local final demand, domestic exports, and foreign exports). Based on statistics for Beijing in 2010, the case Urban Economy is endowed with just 3.53 billion m 3 of local water withdrawal, whereas the total embodied water demand is estimated up to 13.61 billion m 3 , almost quadruple the local water withdrawal. The extra 10.08 billion m 3 of indirect water use is obtained via cross-boundary trade. Overall, Beijing's total water demand is satisfied mainly by domestic imports by a share of more than 60%, and partly by foreign imports by a share of around 20%. The unintentionally induced water embodied in domestic and global trade plays an essential role in satisfying the water demand, which has essential implications for decision making to ease Urban water scarcity.

  • three scale input output modeling for Urban Economy carbon emission by beijing 2007
    Communications in Nonlinear Science and Numerical Simulation, 2013
    Co-Authors: Ling Shao, G Q Chen, Shan Guo, Zhanming Chen
    Abstract:

    Abstract For Urban economies, an ecological endowment embodiment analysis has to be supported by endowment intensities at both the international and domestic scales to reflect the international and domestic imports of increasing importance. A three-scale input–output modeling for an Urban Economy to give nine categories of embodiment fluxes is presented in this paper by a case study on the carbon dioxide emissions by the Beijing Economy in 2007, based on the carbon intensities for the average world and national economies. The total direct emissions are estimated at 1.03E+08 t, in which 91.61% is energy-related emissions. By the modeling, emissions embodied in fixed capital formation amount to 7.20E+07 t, emissions embodied in household consumption are 1.58 times those in government consumption, and emissions in gross capital formation are 14.93% more than those in gross consumption. As a net exporter of carbon emissions, Beijing exports 5.21E+08 t carbon embodied in foreign imported commodities and 1.06E+08 t in domestic imported commodities, while emissions embodied in foreign and domestic imported commodities are 3.34E+07 and 1.75E+08 t respectively. The algorithm presented in this study is applicable to the embodiment analysis of other environmental resources for regional economies characteristic of multi-scales.
