Abstract
The damage caused by pollution is not equal across individuals within a given population, due to the differences in pollution level and coping ability. Identifying the different impacts of environmental pollution on agricultural economic growth and the source of the pollution is of great reference significance for realizing the organic integration of ecological protection and relative poverty alleviation. This study takes marine fishery culture as an example, with the cultured products data of 53 coastal cities in China from 1994 to 2018 and empirically captures the heterogeneous effects of environmental pollution on mariculture growth by constructing a theoretical analysis framework of heterogeneity in pollution damage. Results show that the deepening of marine environmental pollution will reduce the growth rate of marine cultured output, emerging significant regional differences. Nevertheless, under the background of the complex environmental situation currently, further damages mainly derive from the difference in the ability to deal with environmental pollution rather than the difference in pollution degree. In terms of different wastewater sources, the impact of industrial wastewater discharge on marine aquaculture production is not very significant. In contrast, the adverse shocks of urban domestic sewage are more prominent. Notably, the environmental pollution has a significant cumulative effect, which is not reversed. Therefore, a pollution shock in one period may leave the region permanently further behind. Based on this, in the follow-up process of pollution control, we should fully consider the heterogeneity in coping ability of individuals. While promoting industrial wastewater emission reduction, we should emphasize strengthening of the urban domestic sewage treatment strategies and give overall consideration to the ecological environment treatment and regional coordinated development.
Highlights
Since the reform and opening-up policy, while the industry and agriculture enjoy rapid development, it is bringing about severe environmental problems
In order to ensure the accuracy of model regression and avoid the appearance of “spurious regression,” this study carries out stationary test of all variables
The Levin Lin and Chu T statistical magnitude (LLC), which are used to judge the existence of the common unit root, and the Fisher ADF statistical magnitude (ADF), which is used to judge the existence of the individual unit root, are both adopted
Summary
Since the reform and opening-up policy, while the industry and agriculture enjoy rapid development, it is bringing about severe environmental problems. Agriculture restricted by vulnerability and reliance on the natural environment has been subject to various constraints and negative influence of environmental pollution. By resorting to the framework of economics and the econometric model, economic circles have substantiated the negative impact of ozone pollution on grain output. They have predicted that the losses caused by ozone pollution could be as high as 18 billion USD at a global scale, of which 6.45 billion USD would be from China (Wang and Mauzerall, 2004; Powell and Reinhard, 2016; Yi et al, 2016; YI et al, 2020)
