Coordinate Evaluation between Expressway Construction and Economy Development Based on DEA Model

As we all know, the construction of expressway promotes regional economy development enormously. However, the investment for expressway is huge, including cost of manpower and material resource, which may also have negative effects on environment. Thus, the construction of expressway should be adapted to regional economy development and the environmental bearing capacity. Above all, based on the analysis of the interaction between expressway and economy, we choose GDP, population, vehicles and volume of passenger transport and freight transport as the evaluation index, which could reflect the interaction more comprehensive. Then, we construct the DEA model for coordinated evaluation and make a case research with the data of Shandong Province. As a conclusion, the result suggests that the construction of expressway is ahead of its time. And finally, we provide the modified value of expressway’s evaluation index in 2012. The DEA model in the paper is practical to evaluate the coordinated development between expressway and economy, which could be the reference for expressway development.
