摘　　要：本文利用部门间的关联和经济距离来识别黑龙江省农业产业链。部门间的关联根植于部门之间的投入产出存在相互交易,表示相互依存程度;经济距离是一种平均传递长度,表示一个部门的外生性变化对另外一个部门影响步长的平均数。将部门之间的关联和距离结合在一起,我们就可以清楚关于产业链的信息,运用该方法来研究黑龙江省农业产业链。This article identifies the chains of the agriculture industry in Heilongjiang Province with the linkages inter-industry and economy distance. The linkages of inter-sector root in the transaction of input and output, meaning the degree of dependence. Economy distance is the average length of propagation, meaning the average number of steps it takes an exogenous change in one sector to effect another sector. Combining the linkages and the distance, we can see more information of the chains of industry, and with this methods we can research the chains of the agriculture industry in Heilongjiang Province.
