焦化企业工业共生模式实证研究

Empirical study on symbiosis pattern in coke-oven plants

介绍了我国焦化行业发展现状、面临的问题与挑战。按照某一共生单元(企业)在共生链网中的地位和作用,系统地识别和划分了主导型工业共生、平等型工业共生和依附型工业共生3种主要链网模式,总结了各自结构特点和运行模式,并对焦化企业进行了实证研究。主导型工业共生模式往往是以独立型焦化厂为主构成的,一些焦化厂在加强焦化下游产品的开发同时发展了钢铁、化工等耗焦炭量大的产业,构建起平等型工业共生模式,焦炭部分外销;依附型工业共生模式往往是焦化企业在钢铁、化工、动力等流程型生产环节内组成的共生链网,主要通过焦炭供应、焦炉煤气利用构建链网关系,焦炭一般不外销。

The status quo,also some problems and challenges of coke-oven industry in China were introduced. According to unit structure and function in the symbiosis network, the industrial symbiosis pattern could be classed into three types, i. e. dominant type, equal type, and adherent type. The character of the three types was summarized and analyzed, and the empirical study on symbiosis pattern in coke-oven plants was carried out. Symbiosis in stand-alone coke-oven plants is always the dominant type. The symbiosis construction is through utilization of coal tar and coke gas, accommodation of steam and hot water, nearly all coke is sold as a product. Symbiosis of equal type is always developed from stand-alone coke-oven plants. Such plants develop its downstream products and form steel works as an extended industrial chain. The symbiosis construction is through utilization of coke gas and accommodation of coke. Part of coke is accommodated to steel production, else is sold as a product. Symbiosis in coke-ovan plants in iron and steel complex, chemical industry or power is always the adherent type. The symbiosis constrnetion is through utilization of coke gas and accommodation of coke. Nearly all coke is accommodated to the production in its group.
