An Analysis on the Relative Efficiency of the Infrastructure Investment in the Liaoning Coastal Economic Belt Based on DEA Method

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 relative 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 comprehensively 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.
