The Research Of Ecological Industrial Agglomeration

Industrial agglomeration theory research can be traced back to the 19 th century, the Marshall was the first to put forward theory of industrial agglomeration and industry cluster is defined as industrial parks, industrial concentration can generate internal economies of scale and external economies of scale. Then Webb will gather economic development to become a a systematic theoretical system. After the 1950 s, industrial agglomeration theory in the study of relationship between industrial agglomeration and economic growth continuously perfect.Industry cluster can produce agglomeration benefit, its core is the external economy, on the one hand, make the industry lower production costs, on the other hand, to improve yield.Therefore, the industrial concentration can significantly promote the growth of regional economy, in recent years has become a popular choice of parts of the domestic economy.The industrial concentration, cannot separate research from economic growth system cluster form, also cannot from low carbon concept, to expand the scale of industrial pure benefit at the expense of the external environment, and the concept of low carbon development. Such pollution can easily be overshadowed by industrial agglomeration economic benefits of; At the same time, also hide the agglomeration effect to environment can play a positive externalities, make the development of the industry into the opposite of the environment. Industrial agglomeration externalities can, in fact, between industry and industry through some means to achieve the effect of energy conservation and emissions reduction. The construction of industrial concentration is low carbon model is based on this idea, and industrial agglomeration ecology as the development direction of low carbon mode,in domestic has the implementation conditions and material basis. Based on the development direction, the contradiction between economic benefit and environmental benefit opposite can be effectively avoid through the practice of low carbon mode, low carbon energy saving also contains the economies of scale in industrial agglomeration ecology.
