  • Measuring the Efficiency of Fiscal Policies for Environmental Pollution Control and the Spatial Effect of Fiscal Decentralization in China.
    International journal of environmental research and public health, 2020
    Co-Authors: Caihua Zhou, Xinmin Zhang
    Abstract:

    This paper uses both fiscal expenditure policy and fiscal revenue policy as input indicators and selects Environmental Pollution Control results reflecting different forms and sources of Pollution as output indicators. The efficiency of fiscal policies for Environmental Pollution Control (EFPE) of 30 provincial-level administrative divisions in China from 2007 to 2017 is measured by adopting the data envelopment analysis (DEA) method. Then, the spatial effect of fiscal decentralization on EFPE is empirically analyzed by using the spatial lag model (SLM). The results show that EFPE values in China have been greatly improved overall since 2014. The change in technical efficiency (TE) is caused mainly by the change in pure technical efficiency (PTE). EFPE values have regional heterogeneity and convergence. The eastern region has clearly higher EFPE values than other regions. The growth rate of the low efficient region is greater than that of the high efficient region. Fiscal expenditure decentralization has a direct negative effect and spatial spillover effect on EFPE values, while fiscal revenue decentralization has a non-significant effect. Based on these results, this paper proposes the following policy implications: increasing the level of fiscal expenditure of Environmental Pollution Control and improving the central transfer payment system for Environmental protection; reforming the government performance assessment system and innovating the conditions of government expenditure on Environmental Pollution Control; and promoting horizontal fiscal cooperation in cross-regional Environmental governance.

  • Does Fiscal Policy Promote Third-Party Environmental Pollution Control in China? An Evolutionary Game Theoretical Approach
    Sustainability, 2019
    Co-Authors: Caihua Zhou, Hualin Xie, Xinmin Zhang
    Abstract:

    To promote third-party Environmental Pollution Control in China, it is necessary to dissect the mechanism of fiscal policy in third-party Environmental Pollution Control. This study first discusses the acting paths of fiscal policies on third-party Environmental Pollution Control in theory. A tripartite evolutionary game model involving the local government, the polluting enterprise, and the third-party enterprise is established. The replicator dynamics, evolutionary stability strategies, and numerical simulation of the behavior of the three participants are analyzed to further study the acting mechanism of fiscal policy in third-party Environmental Pollution Control. In addition, the influences of other parameters on the implementation of third-party Environmental Pollution Control are evaluated. The results show that the behaviors of the local government, the polluting enterprise, and the third-party enterprise influence each other. Furthermore, strengthening the relevant fiscal policy, reducing the risks of the polluting enterprise and third-party enterprise, and improving the benefit to the local government are conducive to promoting third-party Environmental Pollution Control in China. Based on these results, this study proposes the following policy implications: formulating fiscal policies for third-party Environmental Pollution Control, implementing fiscal policies in a dynamic and progressive manner, improving the market mechanism of third-party Environmental Pollution Control, and strengthening the Environmental performance assessment of the local government.

  • Environmental Pollution Control devices based on novel forms of carbon heavy metals
    Energy & Fuels, 1997
    Co-Authors: A. Brennsteiner, J.w. Zondlo, A.h. Stiller, Peter G Stansberry, Dacheng Tian
    Abstract:

    The use of electrochemistry is an effective means to remove heavy metal contaminants from aqueous effluent streams. In this project, the development and testing of novel carbon materials for the electrochemical removal of heavy metal ions from aqueous wastes have been carried out. Both electroplating and electrosorption were employed by using a packed bed of the carbon material in a flow-through electrochemical remediation cell. The main focus of this work was to develop and test a cathodic material with a large ratio of surface area to volume. To this end, a packed bed of conductive carbon, either as carbon fibers or as carbon foams, was utilized. The increased surface area helps minimize the length of electrode through which the solution must pass. This decreased distance leads to reduced resistance to solution flow. The removal of cadmium, lead, copper, and nickel from aqueous samples using a small-scale electrolytic cell has been demonstrated. Removal efficiencies above 90% have been observed. Continuous removal of lead over a 72 h period was demonstrated at these levels. An effluent concentration below 10 ppm was observed for an inlet solution feed of 100 ppm. The use of electrolytic remediation on waste streams proved successful for the selective removal and recovery of metals. The removal of nickel ions from solution directly onto the bare carbon material was inefficient. By plating a small amount of copper onto the carbon surface prior to use, enhanced removal was obtained. At pH 7.0, a removal efficiency for nickel of 89% was achieved.

  • Environmental Pollution Control devices based on novel forms of carbon
    1996
    Co-Authors: A. Brennsteiner, J.w. Zondlo, A.h. Stiller
    Abstract:

    The use of carbonaceous cathodes is an effective means to remove heavy metal contaminants from aqueous streams. By increasing the surface area of exisitng cathode materials or by using new high surface area materials, improvements in the removal efficiencies are obtained without a vast increase in electrode volume. By careful selection of the appropriate experimental parameters, selective removal and recovery of these metal ions is feasible.
