This paper analyzes the small cosmopolitan and stability of the industrial coupling symbiotic network of eco-industrial parks of oil and gas resource-based cities. Taking Daqing A Ecological Industrial Park as an example, we constructed the characteristic index system and calculated the topological parameters such as the agglomeration coefficient and the average shortest path length of the industrial coupling symbiotic network. Based on the complex network theory we analyzed the characteristics of the scaled world, constructed the adjacency matrix of material and information transfers between enterprises, drew the network topology diagram. We simulated the system analysis and analyzed the stability of the industrial coupling symbiotic network of the eco-industrial park using the network efficiency and node load and maximum connected subgraph. The analysis results are as follows: the small world degree δ of Daqing A Eco-industrial Park is 0.891, which indicates that the industrial coupled symbiotic network has strong small world characteristics; the average path is 1.268, and the agglomeration coefficient is 0.631. The probability of edge connection between two nodes in a symbiotic network is 63.1%, which has a relatively high degree of aggregation, indicating that energy and material exchanges are frequent among all enterprises in the network, the degree of network aggregation is high, and the dependence between nodes is high; when the tolerance parameter is 0 to 0.3, the network efficiency and the maximum connected subgraphs show a sharp change trend, indicating that the topology of the industrial coupling symbiotic network of the eco-industrial park changes drastically when the network is subjected to deliberate attacks. It is easy to cause the breakage of material flow and energy flow in the industrial park, which leads to the decline of the stability of the industrial coupling symbiotic network of the eco-industrial park.

本文分析了油气资源型城市生态工业园区产业耦合共生网络的小世界性和稳定性。以大庆A生态工业园为例，构建了产业耦合共生网络的特征指标体系，并计算了集聚系数，平均最短路径长度等拓扑参数。基于复杂网络理论，分析了可扩展世界的特征，构造了企业间物资和信息传递的邻接矩阵，绘制了网络拓扑图。我们利用网络效率和节点负载以及最大连通子图，对系统分析进行了仿真分析，并分析了生态工业园区工业耦合共生网络的稳定性。分析结果如下：大庆A生态工业园的小世界度δ为0.891，表明工业耦合共生网络具有很强的小世界性；平均路径为1.268，结块系数为0.631。共生网络中两个节点之间进行边缘连接的概率为63.1％，具有较高的聚集度，表明网络中所有企业之间的能量和物质交换频繁，网络聚集度高，节点之间的依赖性很高；当容差参数为0到0.3时，网络效率和最大连接子图显示出急剧的变化趋势，这表明，生态工业园区的工业耦合共生网络的拓扑在受到蓄意攻击时会发生巨大变化。工业园区容易造成物质流和能量流的破裂，导致生态工业园区的工业耦合共生网络的稳定性下降。
