The Empirical Study On The Relationship Between Economic Growth And Pollutant Emission In Huian County

With the concept of sustainable development, the paper mainly focuses on the relationship between environment and economic growth.EKC hypothesis is a tool to summarize the relationship between environment and economic growth. As economy continues to develop, the environment suffers from pollution at the beginning, and then gets better gradually. In principle, some media factors determine the relationship and drive the pollutants and economic forward, such as industrial structure, technology upgrade, import and export trade, population, social consumption, environmental investment and environmental policy.Based on the EKC hypothesis, the paper establishes EKC models between pollutants and income. The result shows no typical Kuznets curve, which reveals that the reversed U-shaped curve is not a unique pattern in EKC empirical study. The reversed U-shaped curve describes a general pattern in a long term history of social and economic progress, in comparison, the diversity of the Environmental Kuznets curve is a concrete reflection to a particular period according to the society, economy and culture. During studied period, the wastewater emission is not harmonious with economic growth, which is a logarithmic linear equation; the relation between SO₂ emission and economic growth is logarithmic cubic equation, only signaling harmonious development at the end of the studied period. If the economic model remained the same, with regard to the petrochemical industry, the relationship between environment and economic growth would go worse in the future.The paper applies both quantitative and qualitative analysis, including co-integration analysis and granger causality test and so on, to demonstrate driving forces between economic and environment. Detailed information about industry structure adjustment, social consumption, population, environmental protection investment is presented to discuss how they affect pollutant amount.We should keep in remind that the turning point of environmental Kuznets curve doesn't occur automatically. To promote a sound and rapid development, the paper takes Huian's situation into account, and then proposes suggestions for policy combination: improving environmental management and administrative ability at county level; taking a new approach to industrialization; increasing investment for environmental protection through diversified channels; defining responsibility of investors, implementing population policy in a steady manner to maintain a low increase; advocating green consumption, besides pollutant amount discussed in the empirical study, paying attention to other ecological problem. In that case, we can make sure a sustainable development in Huian in future.
