节能减排绩效及其与经济效益协调性的监控和评估

设计了节能绩效-减排绩效关系图及节能绩效、减排绩效与经济效益协调关系三角图,研究了1997～2006年中国石油、化工、冶金等行业(包括石油和天然气开采业(O1)、非金属矿采选业(O2)、石油加工及炼焦业(O3)、化学原料及化学制品制造业(O4)、化学纤维制造业(O5)、橡胶制品业(O6)、塑料制品业(O7)、黑色金属冶炼及压延加工业(O8)、有色金属冶炼及压延加工业(O9)和金属制品业(O10))节能减排绩效及其与经济效益的协调性状态和趋势.结果表明,塑料制品业(O7)的节能减排绩效最好,10个被研究的行业中有9个行业属于节能减排绩效很差-差的行业,其中,O3、O4、O8和O10等4个行业节能减排绩效有变差的趋势。2006年,上述行业节能减排绩效与经济效益协调性所处状态的离散程度相对于1997年变大,并分布在5个不同的状态,其中,O1和O2处于强不协调状态,O3处于弱不协调状态,O4、O8和O9处于弱协调状态,O5和O7处于强协调状态,O6和O10个处于很强协调状态;且O1、O2和O3呈弱不协调性发展趋势,O4、O5、O6、O8、O9和O10呈强协调性发展趋势,O7先呈强协调性发展趋势,后成为弱不协调性发展趋势.本研究设计的方法具有简便、直观、灵活和易用等特点,是值得推广的节能减排绩效及其与经济效益协调性监控和评估方法.

Monitoring and evaluation of energy saving and pollution reduction performance (ESPRP) and its coordination with economic benefit

Arectangular coordinate diagram based on the relationships between energy saving performance (ESP) and pollution reduction performance (PRP),and a triangle diagram based on the interrelationships among ESP,PRPand economic benefit,were designed to illustrate the statuses and trends of energy saving and pollution reduction performance (ESPRP) and its coordination with economic benefit,respectively. As a case study,China's petroleum,chemical and metallurgical industries,including petroleum and natural gas extraction (O1),nonmetal mineral mining and dressing (O2),petroleum refining and coking (O3),raw chemical materials and chemical products (O4),chemical fiber (O5),rubber products (O6),plastic products (O7),smelting and pressing of ferrous metals (O8),smelting and pressing of nonferrous metals (O9),and metal products (O10),were selected to evaluate the status and long-term trends of the ESPRPand its coordination with economic benefit from 1997 to 2006. The results show that 9 of 10 industry sectors belong to the very bad or bad ESPRPstatus. The plastic products industry has the best ESPRPperformance status. Four out of ten industry sectors' ESPRP,including O3,O4,O8 and O10,have a trend to become worse in the future. In2006,discrete level of coordination between ESPRPand economic benefit is higher than that in1997. In2006,10 industry sectors distribute in 5 different statuses,O1 and O2 at very strongly uncoordinated status,O3 at strongly uncoordinated status,O4,O8,and O9 at weakly coordinated status,O5 and O7 at strongly coordinated status,and O6 and O10 at very strongly coordinated status; O1,O2,and O3 have weak coordination trends; O4,O5,O6,O8,O9 and O10 have strong coordination trends; O7 has a strong coordination trend first,then a weak coordination trend. The ESP-PRPrelationship diagram and triangle method,as an intuitive platform for illustrating the status and trends of ESERPand its coordination with economic benefit,seems to hold promise as an analytical management tool given its simplicity,ease of use,and flexibility.
