Studies Of Sealand Industrial Optimization Under Environment Restraint In Liaoning Province

Resources and environment is the basis for sustainable economic and social development. Industry structure and industry development of resource consumption and environmental impacts vary. On the base of sea-land resources and environment carrying capacity of the ecosystem, social and economic vitality and potential of the system, this paper analysis the population of the sea-land environment, economic environment and the natural environment system. Subject to the marine environment sustainable development, this paper discusses the basic theories and research methods of sea-land integration. And this paper focuses on land and sea industry coordination and optimization of marine industry structure problems. Meanwhile, by taking Liaoning Province as the case to analyze the correlation degree and coordination efficiency of sea-land industries, the marine industrial structure optimization is studied based on marine industrial input and output and the related countermeasures are put forward. This paper is divided into six chapters.The first chapter is the introduction, mainly focusing on the background and research significance of the selected topic. The research progress is unscrambled and the thinking, research contents, methods and innovation are discussed.The second chapter is about theoretical basis for sealand industry manpower. Through sorting out the basic characteristics of marine economy, the definition of marine economy and industry, classification and characteristics of marine industry, marine environment and restriction mechanism, the optimization of marine industrial structure and its evolution theory are summarized. The basic connotation, core content and basic features of sea-land overall planning are discussed through analyzing the sea-land overall planning theories.The third chapter is the mechanism analysis concerning land and marine industrial coordination and optimization of marine industrial structure under the thought of sea-land overall planning. From aspect of relation mechanism of the land and marine industries and the structural differences of land and marine industries, the coordinated development mechanism of land and marine industries are analyzed. By explaining the internal relation between evolution of marine industrial structure and economic growth and analyzing influencing factors and the driving force of the marine industry structure optimization, the evolution of marine industrial structure and the optimized influencing mechanism are studied.The fourth chapter is focused on the research methods of land and marine industrial coordination and marine industry structure optimization. Through summarizing and evaluating the research methods of marine industrial coordination assessment and marine industrial structure optimization, the favorable research methods to achieve land and marine industry coordination and marine industrial structure optimization are discussed under the background of sea-land overall planning.The fifth chapter is the empirical analysis concerning the industrial coordination and optimization of marine industrial structure of the Liaoning Province. Through the analysis and evaluation of current situation of development of marine economy in Liaoning Province, the degree of association between three marine industries and related land industries are evaluated quantitatively by using the grey complex correlative degree analysis and grey similar correlative degree analysis. DEA method is adopted to estimate the sea-land industrial efficiency in Liaoning Province. Then marine industrial structure optimization is discussed based on input and output and the related countermeasures are put forth.The sixth chapter is the summary and outlook. T he defects are analyzed and research orientation is brought forth.
