Citizens´ Perception of Civil Engineering Quality Based on Data Mining

Quality of the civil engineering in a city can demonstrate the level of economic development, city image and the ability of governance of this specific area. Utilizing data mining method and algorithm, as well as the quality index of the civil engineering constructed from a large scale consumer survey, the results revealed that, as a whole, the quality of civil engineering in China is not quite good. The quality scores of Public Square, theatre, municipal pipeline, and so on, are fall behind the scores of some industry products. Moreover, there is big discrepancy existing in the results collected from different residents and different regions. The quality score of civil engineering in urban area is higher than that of rural area, same result applies from big city, medium city, and to small city as well. Marketization level, economic duality and government governance ability can be the reasons lead to diversity. So, government should reform the mechanism of quality regulation, adopt new strategy of governance to deal with the quality issues in civil engineering.
