Economic and social development is the focus of the national “13th Five-Year Plan”. It is urgent to establish an evaluation index system that has both a significant reflection of the city's economic and social development but also a clear future economic and social development. Such a system can clear planning goals, set standards and promote urban development. From the perspective of the connotation of economic and social development, this paper chooses the indexes of economic development, social livelihood, scientific and technological progress, resources and environment. According to the principle of maximum information content and redundant information elimination, the paper select the index and construct a significant evaluation index system of economic and social development. The innovation and characteristics of the article: First, according to the principle that the greater the difference between the evaluation object and the indexes information content, the more significant the impact of this index on the evaluation results, this paper constructs the Gini coefficient of the index, and removes the smaller Gini coefficient, that is, information content of small indexes to ensure that the index system after screening has a significant impact on the economic and social development. and it also avoids the shortcomings of the existing evaluation system that the indexes do not distinguish the evaluation results clearly, and extend the application of the Gini coefficient. Second, according to the principle that the greater the value of the Gini coefficient, the higher the ability to identify of the index, the greater the information content to remove the smaller Gini coefficient, that is, information content of small indexes in the two index of partial correlation coefficient greater than 0.8. By this way ,the paper can avoid the shortcoming that of the existing evaluation system that the indexes with high discrimination ability may be mistakenly deleted when eliminate those redundant indexes. Third, the empirical results show that: The index system constructed in this paper covers all aspects of economic and social development, reflecting 98.7% of the original information through 37.1% of the indexes. It not only reflects the coordination with the national planning, but also reflects the Dalian city long-term planning continuity and the country's future hot issues.
