收入分配不公是影响社会协调发展的重要因素。为了从微观视角考察结构转型对贫富差距的影响．本文利用非线性阈值协整理论定量刻画了洛伦兹曲线随产业结构变化而发生变动的特征。研究结果表明：随着产业结构的不断变动，洛伦兹曲线斜率的变化具有非线性的特征．即当产业结构偏离均衡相同大小时，洛伦兹曲线恢复到均衡斜率的速度不同：产业结构的“突变”位置发生在结构转型程度为0．014处。该突变值对洛伦兹曲线斜率的影响存在显著的门槛效应，且该门槛效应发生在结构转变后的第3期。由此揭示的经济含义为：在结构发生转变的过程中。我国财政政策和货币政策效果具有滞后性和非对称性的特点,滞后性表现为当结构转型发生之后。洛伦兹曲线在滞后3期才发生明显的非线性变动作用，而非对称性表现为当结构转型发生变动时，我国政府未能兼顾财政政策和货币政策对收入分配所造成的不利冲击。从而导致收入分配不公的程度出现加剧恶化现象。因此,仅仅依靠市场机制对缩小贫富差距的作用不大，政府需要控制政策操作力度以及调整要素适应结构转型。从而达到缩小贫富差距的效果。

Unequal distribution of income is an important factor which influences social coordination development. In order to consider the effect of structural transformation on wealth gap from micro perspective, this article uses nonlinear threshold co-integration theory to portray Lorenz curve＇ s character with the changes in the industrial structure. The results show that the slope of Lorenz curve has nonlinear characteristic with the continuous changes of industrial structure ; that is, when industrial structure deviates from the balanced value, Lorenz curve restores to balance at a different speed. Industrial structure ＂mutation＂ position occurs at the structural transition of 0.014, the mutation value has significant threshold effect on Lorenz curve slope, and the threshold effect occurs in the first three post-structural changes. Thus the article reveals the economic meaning： in the process of structural transformation, China＇ s fiscal policy and monetary policy have hysteresis and asymmetry characteristics. Hysteresis means that when structural transformation occurs, Lorenz curve begins to change obviously in the following three periods. However, symmetry means that when structural transformation occurs, our government fails to take full account of fiscal policy and monetary policy＇ s adverse effect, thus leading to the level of income distribution inequality exacerbates. Therefore, it is less meaningful to narrow the income gap between rich and poor. In order to achieve the effect of narrowing the gap between the rich and the poor, our government needs to control the degree of policy operation and adjust factor to suit for structural transformation.
