Research on challenges and strategies for China’s green economy development

The last 20 years have been the fastest economic developing period of China,and China has made great economic achievements through undertaking international industrial transfer.However,undertaking international industrial transfer has brought about severe environmental problems to China and the process of undertaking international industry transfer is also a process of undertaking international transfer of natural resource consumption and environmental pollution.Nowadays,China has the heaviest ecological burden and highest environmental risk in the world,and is gradually losing international competitive advantages among traditional industries.China is facing unprecedented pressure of economic transformation.Besides the advantages like huge domestic demands and abundant civil capital,China faces more challenges in its green economy development.First,China is still in the middle of industrialization and urbanization processes,hence the huge demands for traditional industries will only last 10-15 more years.Meanwhile,China lacks core technologies for transforming traditional industries,which means these industries will have high shut-down risks.Second,the domestic market share for new green industries is limited,since the market is dominated by traditional energy industries.Third,the value of land,water,mineral,and other natural resources is extremely underestimated because the environmental cost is excluded from the enterprises’cost-benefit calculation.China should foster and expand green industries based on domestic demands,and then strive for competitive advantages in the international market in the future.Therefore,China should focus on the following four points in order to promote green industry development:establishing a forced-upgrading-mechanism for traditional industries,an incentive-development-mechanism for new green industries and a TFP-based(total factor productivity based)economic development evaluation system;promoting the integration of new-type urbanization,new emerging industries,and new employments;taking the model of"technology innovating-patent formulating-standard establishing-market guiding"to enhance the global competitiveness of China’s new emerging industries;and building green consumption patterns in the whole society.     

Has EU ETS caused carbon leakage in the EU carbon-intensive industries?A study from the perspective of bilateral trade

Reducing carbon leakage is one of the important reasons that was put forward by the EU for their border adjustment tax proposal.However,there are not many empirical evidences supporting significant carbon leakage in the EU carbonintensive industries.This paper applied the structural breakpoint test for the time series of import and export of cement,aluminum,and steel between EU and China.No significant structural changes were detected in the import and export of cement and aluminum.However,there proved to be two breakpoints,i.e.,2003 and 2008,in the import and export of steel,in which at the second point the overall level of steel import increased.Furthermore,Granger causality test was applied to the carbon price from European Climate Exchange and the import and export of steel.It was found that the carbon price was the Granger cause for the changes of steel import,but not the Granger cause for the export.The results of the study showed that the impacts of EU ETS on the EU carbon-intensive industries were limited.Among the three industries,partial evidence of carbon leakage was only found in the steel industry.Therefore,reducing carbon leakage could not serve as a convincing justification for border adjustment tax.     

Optimizing Urban Spatial Structure of Lanzhou Based on Geographic Concentration Method of Industries

Geographic concentration of industries is the regionalized distribution of some industries in certain areas, which focuses on the ratio of a certain industry to the whole industries （He and Liu, 2006）. In this paper we explore the improved M function of geographic concentration that adds the parameter of the number of firms according to the definition of geographic concentration of industries. The spatial distribution of the main manufacturing industries of Lanzhou urban area is evaluated based on it. The results of the evaluation imply that the spatial distribution of the main manufacturing industries is more concentrated than that of others in Lanzhou and it can absorb lots of labor forces. But the incidence, competition ability and density of the distribution of enterprises are different for each single sector, and enterprises with different production features are located closely. And three main problems are discovered. Finally, three countermeasures are put forward： locating the industrial enterprises in urban areas in a proper way through planning and policies; adjusting the industrial structure of the inner city; strengthening the local rearrangement of the existing industrial concentration areas.

Optimizing Urban Spatial Structure of Lanzhou Based on Geographic Concentration Method of Industries

Abstract

Geographic concentration of industries is the regionalized distribution of some industries in certain areas, which focuses on the ratio of a certain industry to the whole industries (He and Liu, 2006). In this paper we explore the improved M function of geographic concentration that adds the parameter of the number of firms according to the definition of geographic concentration of industries. The spatial distribution of the main manufacturing industries of Lanzhou urban area is evaluated based on it. The results of the evaluation imply that the spatial distribution of the main manufacturing industries is more concentrated than that of others in Lanzhou and it can absorb lots of labor forces. But the incidence, competition ability and density of the distribution of enterprises are different for each single sector, and enterprises with different production features are located closely. And three main problems are discovered. Finally, three countermeasures are put forward: locating the industrial enterprises in urban areas in a proper way through planning and policies; adjusting the industrial structure of the inner city; strengthening the local rearrangement of the existing industrial concentration areas.     

Devising an integrated methodology for analyzing energy use and CO2 emissions from Taiwan's petrochemical industries

Input-output modeling and multiplier analysis are used to assess Taiwan's five petrochemical industries, based upon their economic contribution and potential impacts on energy consumption and CO2 emission. In addition, a consolidated index system was developed for evaluating energy and economic efficiencies as well as targets for CO2 reduction. Results indicate that petrochemical materials (PM) make a major contribution to economic development, with lesser contributions from plastic materials (PL) and artificial fibres (AF). PM has the highest energy multiplier while PL has the largest induced potential for energy consumption. Plastic and rubber products (PP, RP) are relatively insignificant energy consumers. AF has the highest CO2 multiplier, and its induced potential for CO2 emission is the most significant. The consolidated index shows that the upstream petrochemical industries perform rather poorly in an integrated view of economic, energy, and CO2 emission, and should be seen as the primary targets for CO2 reduction. Investment of the petrochemical industries in Taiwan should be adjusted to improve energy efficiency, economic bases, and lower CO2 emissions.     

Selecting suitable sites for animal waste application using a raster GIS

Rapid growth of intensive animal industries in southeast Queensland, Australia, has led to large volumes of animal waste production, which posses serious environmental problems in the Murray Darling Basin (MDB). This study presents a method of selecting sites for the safe application of animal waste as fertiliser to agricultural land. A site suitability map for the Westbrook subcatchment within the MDB was created using a geographic information system (GIS)-based weighted linear combination (WLC) model. The factors affecting the suitability of a site for animal waste application were selected, and digital data sets derived from up to 1:50,000 scale maps were acquired. After initial preprocessing, digital data sets were clipped to the size of the delineated subcatchment boundary producing input factors. These input factors were weighted using the analytical hierarchy process (AHP) that employed an objectives-oriented comparison (OOC) technique to formulate the pairwise comparison matrix. The OOC technique, which is capable of deriving factor weight independently, formulated the weight derivation process by making it more logical and systematic. The factor attributes were classified into multiple classes and weighted using the AHP. The effects of the number of input factors and factor weighting on the areal extent and the degree of site suitability were examined. Due to the presence of large nonagricultural and residential areas in the subcatchment, only 16% of the area was found suitable for animal waste application. The areal extent resulting from this site suitability assessment was found to be dependent on the areal constraints imposed on each input factor, while the degree of suitability was principally a function of the weight distribution between the factors.
