Abstract
The infrastructure construction is playing an important role in the development of Liaoning Coastal Economic Belt, whereas a calculation and analysis on the relative efficiency of its 6 cities’ infrastructure investment will offer a useful reference to the decision on the future investment scale and structure of this area’s infrastructure. Based on DEA model and from the viewpoint of constant scale return and changing scale return, this paper calculates the comprehensive rela- tive efficiency and scale relative efficiency of the infrastructure investment in Liaoning Coastal Economic Belt in 2000-2009, and draws the following conclusion: Infrastructure investments in Dalian, Jinzhou and Panjin are compre- hensively relative efficient, while infrastructure investments in Dandong,Yingkou and Huhudao are comprehensively relative inefficient. Infrastructure investments in Yingkou and Huludao are technically efficient, but inefficient in the sense of scale, and are taking increasing scale returns, while the infrastructure investment in Dandon is inefficient from both the technology and scale senses, and is showing a decreasing scale return.
Highlights
The term of “infrastructure” was introduced to the field of economics in the 1940s, economists have much earlier realized the importance of public facilities such as the navigation, port, warehouse, and water conservancy project

Summary
The term of “infrastructure” was introduced to the field of economics in the 1940s, economists have much earlier realized the importance of public facilities such as the navigation, port, warehouse, and water conservancy project. Its basic idea is to spread the single-input and single-output engineering efficiency concept to the effectiveness assessment of decision- making unit with multi-input and multi-output, to apply the mathematics planning to assess the relative effectiveness of multi-input and multi-output “unit”. It decides whether the DMU is effective by the means of its observation data, essentially, it decides whether the DMU is located in the leading edge of production possible anthology. Based on DEA model and from the viewpoint of constant scale return and changing scale return, this paper aims to analyze the comprehensive relative efficiency and scale relative efficiency of the infrastructure investment in the Liaoning Coastal Economic Belt in 2000-2009
