China's Urban Economic Benefit Analysis

With the development of our national economy, people live to oneself of cities and urban environment put forward more and more high demand, the city planning, layout, construction, traffic, environmental protection etc. Get the increasing emphasis on all levels of government. Reviewing urban development, the research of urban development law, explore urban development direction, make urban development strategy and planning, seeks the modern urban scientific management approach, has become each city managers and even every city citizen issues of concern, urban economics and therefore produced, urban economic benefit is part of the study of urban economics, analyses city economic benefit can help research how to develop the city.The principal component analysis is in the same problems involved in many the features of the correlation between, namely each feature information between "overlapping" sexual start,use a less, independently new information features to instead of original features to provide most information, then based on the new with less information characteristics to solve the problem.Principal component analysis of the basic idea that the multiple feature mapping for few comprehensive features, the purpose is dimension reduction.Clustering analys is according to the similarity between the sample and the sample to classification, a prior to a batch don't understand its category of samples are classified, similar into categories, no similar into another. Clustering algorithm has a lot of kinds, such as: neighbor clustering method, the maximum minimum distance method, hierarchical clustering algorithm, dynamic clustering algorithm, simulated annealing clustering algorithm etc.Regression analysis, is the study of the statistical relation between variables of a statistical method.,It from the independent variable and dependent variable of a group of observations aesthetics, and find a function type, between variables statistical correlation will expression comes out, the functional can approximation of the relationship between independent variable and dependent variable called regression equation or regression function.This paper based on principal component analysis cluster analysis, and regression analysis theory, using China 35 major cities on the end of 2008, the total population, the gross domestic product, total industrial output value, passenger amount and freight amount, local financial budget income, investment in fixed assets, urban and rural residents, on-the-job worker number in saving balance, on-the-job worker total wages,urban and rural residents, on-the-job worker number in saving balance, on-the-job worker total wages, ten indexes of data, the application of matlab software statistical analysis to study the city's development speed , and the gross domestic product (GDP) and other indicators relationship. And through the dalian 1991 to 2008 statistics analysis to the GDP , industrial output, the urban and rural residents of savings, investment in fixed assets, on-the-job worker is average number of long-term stability relationship.
