洛伦兹曲线模型研究是近年来收入分配领域较为活跃的研究领域之一，本文先提出了几种应用效果良好的模型，用国外文献中通常采用的方法与国际上通用的数据对这些模型的应用效果进行了分析，说明新模型远优于利用现有文献中模型构造的模型。然后将其中效果最好的模型用于研究我国的收入分配。本文使用了湖北省2009年、2010年、2012年三年的收入分配抽样数据，用其形成分组数据，然后用新洛伦兹曲线模型对产生的分组数据进行拟合，再利用拟合得到的模型估算基尼系数，证明由此得到的基尼系数与从样本数据计算得到的基尼系数基本相同。估算得到的洛伦兹曲线几乎准确地通过分组数据点。说明本文提出的洛伦兹曲线模型具有重要的应用价值，适用于研究我国的收入分配。对湖北省收入分配数据的分析说明，我国城乡收入分配中财产性收入不平等最严重，甚至部分人口尚无财产性收入。农村转移性收入的数量或比例还落后于城镇。

The research of Lorenz Curve model is an active research field in the income distribution analysis. This paper puts forward several effective models, and applies these models to international data widely used in the literature, showing that the new models are far better than those models which are used in the literature. Then the best model found is used to study the income distribution of China. This paper uses 2009,2010,2012 income distribution sample data of Hubei province, forming grouped data, then uses one of the new Lorenz Curve models to fit the grouped data, estimates the Gini coefficient, and proves that the resulting Gini coefficient is very close to the Gini coefficient calculated from the sample data. The estimated Lorenz Curve almost accurately passes the grouped data points. So the proposed Lorenz Curve model has important application value, which is suitable for the study of income distribution of our country. The analysis of income distribution of the province shows that the property income inequality is the most serious, and some population have no property income at all. The number or proportion of rural transfer income still lags behind that of the urban area.
