Economic Globalization and Industrial Pollution

Abstract

In order to study the relationship between economic globalization and industrial pollution, this paper developed the theoretical framework and used simultaneous equations. The result shows that economic globalization has influences on the industrial pollution mainly by the direct effect of scale, structure and technology as well as the indirect effect of income and policy. Considering all the factors, economic globalization, especially foreign direct investment (FDI), will reduce industrial pollution, in which technology spillover effect plays an important role.     

Detailed Ecological Footprint Accounting of Liaoning in 2006

Abstract

Ecological footprint (EF) has received considerable attention as a useful indicator in the context of sustainable development. So far, EF has been used in numerous studies by academies, organizations and government authorities. However, the results of these studies failed to be comparable directly with each other due to imprecise data sets, unmodified accounting methods of pasture and fossil energy, ignored secondary products, undefined process of calculating yield factors and improper biocapacity for biodiversity. In this paper, we elaborated on EF estimating methods from six categories of consumption in order to overcome the limitations above. We adopted precise data and revised methods, calculated EF of some secondary products, introduced weighted factor to calculate yield factors and adjusted biocapacity by an appropriate amount. Meanwhile, we investigated the resource consumption of Liaoning Province in 2006 to assess EF. Its results showed that Liaoning Province overused its natural capital and was in an unsustainable state. We concluded that two specific problems that had arisen in EF assessment and gave some suggestions for Liaoning Province to improve its unsustainable state.     

Carbon Embodied in International Trade of China and Its Emission Responsibility

Abstract

Carbon emissions embodied in international trade of China during 1997–2007 are accounted by input–output method based on Chinese input–output table and global trade analysis project database. It is revealed that carbon emissions embodied in imports and exports both increased during 1997–2007, but carbon emissions embodied in exports are greater than those embodied in imports, China is a net export nation in embodied carbon. The net exports of embodied carbon account for about 10.82% of the total carbon emissions in 1997, dropped to 7.15% in 2002, increased to 13.13% in 2006, and slightly dropped to 12.64% in 2007. Low-end position of international industry division is an objective factor of being a net exporter of embodied carbon for China, and usage of a large amount of obsolete energy-using equipments wasted much energy and increased carbon emissions embodied in exports. Importers should take more responsibilities for carbon emissions embodied in trade, and China should take a certain responsibility for unreasonable energy dissipations too.     

An International Comparative Analysis on China’s Economic Growth and the Convergence in Energy Intensity Gap and Its Economic Mechanism

Abstract

In this paper, the authors have empirically analyzed the convergence in per capita GDP gap and the convergence in the variation of energy intensity with respect to the change of per capita GDP between China and eight developed countries. Then, the authors run a regression on the impact of decisive factors of economic growth on energy intensity and its change, so as to find out the economic mechanism of energy intensity gap changing with respect to the variation of economic growth. This study concludes that: First, there is a convergence in per capita GDP gap between China and the eight developed countries. With the convergence in per capita GDP gap, the energy intensity gap between China and eight different countries also converge, and the convergence rate of the latter is faster than that of the former, i.e. if the per capita GDP gap between China and the eight developed countries decreases by 1%, the energy intensity gap between them will correspondingly decrease by 1.552%. Second, the energy intensity decreases with the improvement of industrial structure, the rising of energy prices, the advances of technology, and the expansion of investment in fixed assets, and it slightly increases with the increase of FDI. Third, the energy intensity gap between China and eight developed countries narrows with the lessening of the difference in fixed assets investment, energy prices, and technological progress between China and eight developed countries, yet increases with the narrowing of the difference in FDI, and has no significant correlation with the difference in industrial structure. Fourth, the narrowing of difference in per capita GDP between China and the eight developed countries can result in the lessening of energy intensity gap, whose economic mechanism is that the decisive factors, such as difference in investment, technology, and the competition mechanism of prices, which can determine the difference in economic growth, can significantly affect the energy intensity gap.     

Can Labor Out-Migration Reduce Firewood Consumption by Rural Households in Western Mountainous China

Abstract

The relationship between out-migration of labor in the Qinling mountain area and households’ firewood consumption is explored. Migration and remittances reduce households’ firewood consumption due to increases in both income and opportunity cost of firewood collection. Previous studies have been equivocal because they ignored uncertainty in household economy, which is widespread in forest areas of less developed countries. This study provides additional insight by considering vulnerability and subjective assessment of poverty generated by unstable income and an uncertain future. We provide evidence that the amount of firewood consumed depends on income and opportunity cost of firewood collection, but also on a prudent consumption strategy, due to farmers’ subjective assessment of their future possible poverty. We also find out-migration of labor can reduce per capita firewood consumption but subjective poverty also acts against reduction of firewood consumption.     

The Belt and Road Initiative and the 2030 Agenda for Sustainable Development: seeking linkages for global environmental governance

ABSTRACT

Global environmental cooperation serves as an important part in the Chinese ideal of building a Community with a Shared Future for all Human Beings. The report of 19th CPC National Congress indicates that China is committed to proactive mitigation under the Paris Agreement and further participating in global environmental governance under the 2030 Agenda for Sustainable Development, and both of which are largely integrated to the Belt and Road Initiative (BRI). BRI are also closely linked with South–South environmental and climate cooperation proposed by China from previous UN summits. Based on shared ideas, intersected agendas, and compatible governance approaches, BRI and the 2030 Agenda for Sustainable Development grow increasingly relevant and they might form synergies based on increasingly interactive relations. In sum, seeking and intensifying the linkages between BRI and 2030 sustainable development goals (SDGs) could address global environmental governance deficits and enhance cooperation among nations.     

Industrial layout reconstruction,the role of local government and variation of pollution distribution in China

ABSTRACT

In recent years, high-polluting industries have been gradually shifted from the eastern developed regions to the central and western underdeveloped regions in China. Certain environmental regulations have been in place accordingly in various regions, but the pollution in the central and western regions has risen sharply. Based on the data of interprovincial panel in China from 2006 to 2015, this paper calculates high-pollution industry dynamic agglomeration index, environmental pollution agglomeration index and relative environmental regulation intensity index, and uses Generalized Method of Moments to carry out the regression analyses of the whole samples, regional heterogeneity and temporal heterogeneity. The results show that there is an inverted U-shaped relationship between relative environmental regulation and environmental pollution concentration in China. The concentration degrees of industrial wastewater pollution and industrial waste gas pollution are deepened, which are mainly caused by the transfer of highly polluting industries. However, the concentration of industrial solid waste pollution caused by the transfer is not obvious. Furthermore, the deepening of industrialization intensifies the concentration of regional environmental pollution. Environmental Kuznets Curve does exist in China, but it is not significant. The increase of labor cost and quality will reduce the concentration of environmental pollution.     

基于环境容量的县域农用地土壤重金属风险概率预警研究

《土壤污染防治法》的正式出台,标志着我国土壤污染防治工作由"现状治理"转向"风险预防",为此开展区域土壤重金属风险预警研究具有一定的理论与现实意义。以太湖沿岸某产粮县为研究对象,以2015年为基准年,运用重金属输入-输出通量模型和土壤环境负载容量法对研究区耕地土壤中的As、Hg、Cr、Cd、Pb 5种重金属15年(2030年)与35年(2050年)后的风险概率进行预警研究。研究结果表明:大气干湿沉降成为除As以外其他4种土壤重金属的主要来源,畜禽粪便、化肥投入与灌溉水也会在一定程度上影响土壤重金属输入;此外,研究区耕层土壤中As、Cr、Pb 3种重金属整体情况较为良好,Hg、Cd污染风险概率较高,主要分布在研究区中部的O镇、P镇。通过GIS技术与区域物质流通量模型的结合能够很好地对不同区域以及不同重金属污染类型的区域进行风险预警,这可以为土壤污染差别化管控策略的制定提供重要思路。     

基于复式记账的土地资源资产核算与报表编制研究

借鉴会计学复式记账核算的优点,在国际资源核算体系的基础上,根据我国自然资源资产核算需求,提出土地资源资产核算的复式记账体系和报表编制框架。研究认为,基于复式记账的土地资源资产核算和报表编制要以“摸清家底、反映自然资源负债、提供土地资源审计和绩效考核信息”为目标,明确区、县级自然资源局为土地资源资产受托管理和进行土地资源资产核算与报表编制的核算单位。在界定土地资源资产、负债和权益相关概念的基础上,提出土地资源资产属性变化的核算内容和每次土地资源资产实物量变化必须遵循占补平衡的基本原则,进行过程核算。以YC县土地资源资产变化为例,对土地资源资产变化进行了基于复式记账的土地资源资产核算与报表编制实证研究,确定核算的事项类型和特征及其借贷核算流程,编制出土地资源资产负债表,并同时进行实物量核算和价值量核算的报表编制,结果表明:YC县土地资源资产实物量1485 km^2,2018年末价值量5639874.22万元、经济权益5271874.22万元、生态权益367991.6万元,土地资源负债8.40万元,通过土地资源资产用途调整,土地资源资产价值量增加21319.42万元,但在调整过程中,形成了土地资源负债0.07 km^2(8.4万元),在以后土地整治中需要增加园地。     

The application of system dynamics in different practices of a waste management system

The continuous increase in waste generation warrants global management of waste to reduce the adverse economic, social, and environmental impact of waste while achieving goals for sustainability. The complexity of waste management systems due to different waste management practices renders such systems difficult to analyze. System dynamics (SD) approach aids in conceptualizing and analyzing the structure, interactions, and mode of behavior of the complex systems. The impact of the underlying components can therefore be assessed in an integrated way while the impact of possible policies on the system can be studied to implement appropriate decisions. This review summarizes various applications of SD pertinent to the waste management practices in different countries. Practices may include waste generation, reduction, reuse/recovery, recycling, and disposal. Each study supports regional-demanding targets in environmental, social, and economic scopes such as expanding landfill life span, implementing proper disposal fee, global warming mitigation, energy generation/saving, etc. The interacting variables in the WMS are specifically determined based on the defined problem, ultimate goal, and the type of waste. Generally, population and gross domestic product can increase the waste generation. An increase in waste reduction, source separation, and recycling rate could decrease the environmental impact, but it is not necessarily profitable from an economic perspective. Incentives to separate waste and knowledge about waste management are variables that always have a positive impact on the entire system.
