Transportation In China The Development Of Statistical Analysis

Integrated with domestic and foreign economical theory that people have obtained common consensus, mainly based on data in Yearbook of China Transportation & Communications, making use of exploratory data analysis method and factor analysis method etc., the dissertation aims to find out the law and tendency of communications and transportation's development, make economic forecasting, test reliability and feasibility of all sorts of economical theory and recommend for all or different governments and enterprises. The dissertation provides more beneficially quantity basis to make concrete policy and make forecasting by the departments of Communications.Experience and theoretical research make people recognize that classic statistical technology may show quite bad, when real occasions diverge from ideal model described by strict hypothesis. Exploratory data analysis is a copious kind of method to investigate in detail a cluster of data. It lay special emphasis on probing into the data with good flexibility before comparing the data with probability model. Exploratory data analysis separates pattern and characteristic from data and shows powerfully them to the analyst. The analyst usually makes exploratory data analysis and then selects structural or random measure of weight confidently; the analyst still can use exploratory data analysis to unexpected data deviation from common model. The essential of exploratory data analysis method is flexibility: it gets with not only the structure of data with good flexibility, reacts to the pattern with good flexibility which the later analysis steps expose. The dissertation makes use of exploratory data analysis method where analyzing the tendency to communications and transportation's development and obtains comparatively ideal result.The contents of the dissertation's each chapters and sections are arranged:Chapter one makes general descriptive statistical analysis to the situation of China communications and transportation's development since China was built up.Chapter two sets forth evaluation index system, analysis method and characteristic of the situation of China communications and transportation's development.Chapter three selects some economical index which represents the situation of China communications and transportation's development, for example, turnover of freight traffic, turnover of freight traffic and output of communications and transportation, uses statistical graphs, charts or tables, multiple regression, exploratory analysis method etc., and finds out the factors influencing China communications and transportation's development, based on the characteristics of China communications and transportation.Chapter four makes overall evaluation to the situation of China communications and transportation's development in the means of factor analysis, builds up factor score model, calculates factor score and analyzes law of China communications and transportation's development.The dissertation's main contribution lays in using exploratory data analysis method.
