Through refining the ability of distribution center node and combining the national political factors, this paper proposes an improved P-median model, which considers the constraints of the import operation scale, export operation scale and intermediate operation capability of each candidate distribution center node and mandatory nodes. Finally, this paper takes a large express logistics enterprise parcel transportation network as an example to analyse the optimization result of case and parameter sensitivity of node service scope. We find that the optimized layout of the distribution center breaks the administrative division constraint, realizes the nearest transit of parcel, fully considers the scale of each operation of the node, and meets the requirements of mid-to-long term development trend of the parcel express transportation network, which has reference significance for the development of the parcel transportation business and the research on site selection model.
