文章利用生产函数,对2004—2008年全疆与新疆三大区域的面板数据进行线性回归分析,从而对新疆建设用地扩张对二、三产业经济增长的贡献进行研究。结果表明:2004—2008年新疆二、三产业经济增长的要素弹性系数从大到小依次为建设用地、二三产业从业人数、资本存量,弹性系数分别为0.635、0.603、0.326,与此相反,其经济增长的贡献率依次为1.54%、15.04%、17.44%;新疆三大区域二、三产业经济增长的建设用地弹性系数南疆最高,其次是北疆,分别通过在1%、10%的水平上通过显著性检验,而东疆的没通过检验。虽然,当前新疆总体上处于工业化初级阶段,但是不同区域发展水平存在明显的差异,东疆和北疆的发展水平较高,而南疆地区较落后。因此,应考虑新疆不同地区所处发展阶段不同,疆内实行差别化的耕地保护战略,以保证新疆社会经济的可持续发展。
By using the production function, this paper conducts a linear regression analysis on the panel data of Xinjiang and Xinjiang from 2004 to 2008 so as to research the contribution of construction land expansion in Xinjiang to the economic growth of secondary and tertiary industries. The results show that from 2004 to 2008, the factors of elasticity of economic growth of the secondary and tertiary industries in Xinjiang are as follows: the land for construction, the number of employees in the secondary and tertiary industries, the capital stock and the elasticity coefficient are 0.635,0.603,0.326, respectively. On the contrary, The contribution rate of economic growth was 1.54%, 15.04% and 17.44% respectively. The elastic coefficient of construction land for economic growth of secondary and tertiary industries in three major regions of Xinjiang was highest in southern Xinjiang, followed by northern Xinjiang, The level of significance through the test, while the East did not pass the test. Although Xinjiang is generally in the initial stage of industrialization at present, there are obvious differences in the level of development in different regions. The development level in East and North Xinjiang is relatively high, while that in South Xinjiang is relatively backward. Therefore, different stages of development in different regions of Xinjiang should be considered, and differentiated cultivated land protection strategies in Xinjiang should be considered in order to ensure sustainable social and economic development in Xinjiang.
