Conclusions and Policy Implications of this Book

Income distribution, as a research topic, has never lost its attractions to economists. Since the research about income distribution by Ricardo (1981), classical theory, neoclassical theory, Keynesian theory and modern economic theory have never stopped their study about income distribution throughout the history of past 200 years. Generally, income distribution can be divided into two aspects, i.e., size income distribution and functional income distribution. Size income distribution discusses the distributional relationship among different groups while functional income distribution focuses on distributional relationship of income among different factors.
