The cleaner production technology innovation effect of environmental regulation policy: evidence from China

PurposeEnvironmental regulation policy and cleaner production technology innovation are the key links to achieve sustainable economic development. This paper tests the impact of Two Control Zone (TCZ) environmental regulation policy on cleaner production technology innovation and explains the heterogeneity effect between them from the perspective of regional pollution intensity and R&D investment scale.Design/methodology/approachThis paper takes TCZ policy as an environmental regulation policy and collects the patent data related to coal desulfurization cleaner production technology innovation in prefecture-level cities from 1994 to 2002 in China. This paper also tests the relationship between TCZ environmental regulation policy and cleaner production technology innovation based on difference in difference (DID) model. Take regional R&D investment scale and pollution intensity as category variables and analyze the heterogeneity effect of TCZ environmental regulation policy on cleaner production technology innovation based on difference-in-difference-in-difference (DDD) model.FindingsTCZ environmental regulation policy effectively promotes China's cleaner production technology innovation, but it is more conducive to cleaner production technology innovation in heavy pollution areas. With the increasing of R&D investment scale, the positive effect of TCZ environmental regulation policy on cleaner production technology innovation is stronger.Research limitations/implicationsOn the basis of this study, the authors should further explore the regulatory factors of the relationship between TCZ environmental regulation policy and cleaner production technology innovation and further expand the research object, so as to make the research conclusions more practical and instructive.Originality/valueThis paper tests the impact of TCZ environmental regulation policy on cleaner production technology innovation based on the prefecture city level data and DID model, and it handles the endogenous problem caused by the missing variables and provides the accurate conclusions. Moreover, this paper examines the heterogeneity effect of TCZ environmental regulation policy on cleaner production innovation from regional R&D investment scale and pollution intensity two hands and expands the existing theoretical research.

Making Clean Firms Cleaner: Targeting Environmental Regulation to Maximize Returns

Many environmental regulations are designed to clean up the dirtiest firms. However, if pollution intensity is negatively correlated with market share, this approach may not be the most cost-effective way to reduce pollution. This paper illustrates the theoretical conditions under which it is more cost effective to incentivize pollution intensity improvements among relatively cleaner firms. I provide a decision rule for regulators designing pollution reduction policy, and I show that the California wholesale electricity sector exhibits investment behavior consistent with the trade-off implied by this rule.

Environmental sustainability of Russian regions: energy and carbon intensity of regional economy

The article deals with one of the main elements of strategic sustainability of Russian regions - environmental and energy sustainability. The author proves the interrelation of energy and pollution intensity of regional economy. The article presents results of the factors analysis affecting the changes in energy and pollution intensity of GRP. The study allowed to draw conclusions about the most important factors to be taken into account in the formation of environmental and energy policy in regions. In addition, the article provides recommendations for the strategy of sustainable development in the regions of Russia.

Análise comparativa do desempenho elétrico de isoladores tipo pino sob diferentes condições de poluição

<p>This paper analyzes the performance of insulators subjected to pollution levels related to two topologies of 15 kV voltage class polymeric distribution isolators. A software was used to simulate the influence of various levels of pollution on the operation of insulators. Pollution layers with the variation of conductivity and permittivity parameters were modeled on the surface of the insulators and the electric potential, the electric field and the current density in the polymeric isolators were obtained by computer simulation. The results showed the increase of the electric potential distribution, the electric field and the current density of the insulators as the pollution intensity increases. The results proved that the topology with four sheds performs better in polluted conditions. Thus, it can be concluded that in long distribution lines different insulator topologies can be used, according to the region and microclimate that the insulators are exposed.</p>
