新疆人均收入和收入不平等的增长与收敛——基于空间面板模型

新古典经济增长模型预测,随着时间的推移,人均收入的差距将会缩小,收入不平等将会逐渐趋同。本文利用1995年—2012年新疆15个地州的空间面板数据,采用跨部门模型和空间面板数据模型,并考虑空间交互效应来检验上述预测对新疆的正确性。研究结果显示,在对教育程度、失业、产业构成、人均收入的空间滞后增长以及区域固定效应进行调控之后,人均收入存在条件收敛,而收入不平等则存在无条件收敛。

Growth and Convergence in Income Per Capita and Income Inequality in Xinjiang---Based on the Spatial Panel Model

The neoclassical growth model predicts that there will be both a reduction of income per capita disparities over time and long - term convergence in income inequality levels. This paper analyzes the spatial panel data from 15 regions and prefectures from 1995 to 2012 in Xinjiang by employing cross - sectoral model and spatial panel model to prove whether the above prediction is true in Xinjiang, taking spatial interactions into account. The results reveal that the conditional convergence exist in income per capita after controlling education, unemployment, sectoral composition, regional lagged income growth per capita, and regional fLxed effects, and an unconditional convergence exist in income inequality.
