基于MRIO对铁矿石开采生态补偿新机制的探讨

基于多区域投入产出（MRIO）方法，从需求端出发，研究了2010年中国省域间贸易隐含铁矿石的情况，识别了铁矿石消费的重点省份与重点部门.研究结果显示：2010年贸易隐含铁矿石总调出量最大的省份为河北省、辽宁省与内蒙古省，均是铁矿石开采大省；总调入量最大的省份为江苏省与浙江省，位于东部沿海地区，经济较为发达.河北省净输出了3.5亿t贸易隐含铁矿石，占全国开采量的32%.铁矿石开采大省将大量的贸易隐含铁矿石输出到东部沿海地区，以满足当地对建筑业与设备制造业的最终需求.最大的贸易隐含流发生在河北省与浙江省之间，河北为浙江提供了3030万t贸易隐含铁矿石，其中绝大多数进入到浙江的建筑业.

A new eco-compensation mechanism for iron ore extraction based on multi-region input-output analysis

China's interprovincial trade embodied iron ore network in 2010 was analysed by applying a multi-region input-output (MRIO) model. From the demand-based analysis, some key consumers, either provinces or sectors, were identified. Results showed that in 2010, Hebei, Liaoning and Inner Mongolia were the most important exporters of trade embodied iron ore, which were also important iron ore extractors; Jiangsu and Zhejiang were the greatest importers, which were better developed regions located in eastern coastal area. The net exportation of Hebei was 350million tons, which was approximately 32% of the national extraction. Those important iron ore extractors exported most of trade embodied iron ore to eastern costal area, to meet the final demand of construction and machinery sectors. The largest trade embodied flow was the one between Hebei and Zhejiang. Hebei exported 30million tons of trade embodied iron ore to Zhejiang, and most of which was sent to the construction sector of Zhejiang.
