Large-scale construction company plays a vital role in the infrastructure construction. Constractors are commonly seen working on concurrent projects, and single-project-oriented way of construction management can no longer meet the increasing demand of firm growth. Programme management has more advantages than project management. Research on the interaction between the construction projects and contractor becomes necessary. In this paper, theoretical analysis on programme contracting, the organic growth and growth stages of firm, is applied to investigate the coupling interaction of programme contracting and firm growth. Growth stages are identified and key influential factors of each stage are discussed. The result provides a solid theoretical basis for future evaluation and decision making of corporational programme contracting.
