A Study On The Interplay Between The Coastal Economic Growth And The Marine Environmental Pollution

The land of China’s11Coastal Provinces which accounts for13%of the wholearea created60%of the national wealth. The result attracts the world’s attention. Butwith the rapid economic development in coastal areas, the marine environmentalpollution is becoming more and more serious, marine life decreases because of thepollution of human behavior. Therefore, studying on the relationship between theeconomic growth in China’s coastal areas and pollution of the marine environment,the rational development and utilization of marine resources, the protection of themarine environment, have important theoretical and practical significance to promotethe healthy and coordinated economy development in coastal areas.The paper targets the relationship between the economic growth in coastal areasand the marine environment pollution by using the methods of qualitative analysis andquantitative analysis, normative analysis combined with empirical analysis, based onthe authority of public data, and a variety of econometric techniques, using multiplemodels, from different levels, different latitudes, different angles, Attempts to masterthe real state of the mutual influence mechanism as well as the influence to relativelyaccurately so as to provide policy recommendations for comprehensive managementof economic development planning and the marine environment at all levels ofgovernment. Meanwhile, it tries to explore a new way for the study of economicgrowth in coastal areas and the marine environment pollution relations and provides anew perspective to study more scientifically, comprehensively, more profoundly, andmore objectively.This paper consists of three parts. The first part builds marine economy andmarine environment four analysis model by VAR analysis technology. Based on theunit root test and cointegration test for the data, using statistical analysis method to determine the VAR lag order number, and then the model fitting and stability test, itanalyzed the estimation results in the impulse response function and variancedecomposition method. The second part uses the panel data econometric analysistechnology, which contains both time series information and section information, andbuilds three environmental Kunzites curve analysis model. Based on the unit root andcointegration analysis, determined according to the model of data, it implements themodel fitting and estimation analysis. The third part sets up the simultaneous equation,which includes three elements of the production function and the logarithmic linearthree environmental Kunzites curve as the main body of simultaneous equations. Thecoefficients of the equation of four simultaneous national areas, the Yellow Sea area,the East China Sea and South China Sea Area have been estimated. With the scenarioanalysis method for the four model the dynamic impact, based on actual data, itobjectively analyzes the status of the marine economy and environment in ourcountry.The main conclusions which are drawn by VAR model analysis are: red tide isincreased with marine second industry growth. The marine shipbuilding industry andthe pollution of the marine environment have greatly changed the red tide area. Theoil pollution and heavy metal pollution of cadmium could reduce the total marineeconomy. The concentration of dredged material numerical and seawater copperhigher response to the total marine economy. The main conclusions of the analysis ofpanel data model are: the economy of11coastal areas and the pollution of the marineenvironment have the same way and trend of development. The environmentalKunzites curve showed "N" shape. The pollution of the marine environment isdeteriorating in experienced a short period of improvement. The main conclusions bythe simultaneous equation model are: the changes in the industrial structure have littleeffect on the pollution of the marine environment. The economic growth can’timprove the marine environment pollution. The environmental protection investmentis not to improve environmental contamination.This paper shows that there is a complex relationship between economic growth in coastal areas and the marine environment pollution. Not only different indexeshave different effect mechanism, but also the same indicators in different regions arealso different. So we should grasp the relationship between economic growth incoastal areas and the marine environment as a whole, according to the relationshipbetween different regions and different variables, taking different measures to control.
