摘要
保持重点生态功能区居民收入较快增长对促进其生态保护与建设意义重大。文章测算了2010、2020年全国首批重点生态功能区3个空间尺度的居民收入水平,利用尺度方差、Dagum基尼系数、核密度估计以及计量经济模型等方法分析了居民收入的时空变化特征及驱动因素。结果表明:①居民收入增速快于全国,但收入水平明显低于全国。以胡焕庸线为界东侧增速慢于西侧,但东高西低的收入绝对差距扩大。以秦淮线为界,南方增速快于北方引致收入北高南低转为南高北低。②居民收入水平的区域差异明显收敛,但差异依然较大。收入差异由主要体现在县区尺度转为县区和功能区尺度均比较明显。大区尺度差异主要表现为各大区的内部差异,大区间差异主要是西部与其他大区间的差异。③县区与功能区尺度收入的趋势面特征及变化趋势相似,中部和西部的趋势面变化不明显,东部和东北变化较大。④驱动因素趋向多元化,因素作用总体增强。城镇化、人口规模、农业发展、地方财政是重要驱动因素,经济发展主要通过传导机制起作用。应加快城镇化、推进绿色发展、促进就业、优化财政资金使用、实施差异化政策等以提高居民收入。
To maintain a relatively fast growth of residents'income in key ecological function areas is of great significance to promote the ecological protection and construction.This study measured the residents'income level at three spatial scales in the first batch of national key ecological function areas(NKEFA)in 2010 and 2020,analyzed the spatial-temporal characteristics and driving factors of residents'income level using the methods of scale variance,Dagum Gini coefficient,kernel density estimation,and econometric model.The results show that:1)The growth rate of residents'income level is faster in NKEFA than that at the whole country,but its income level are still significantly lower than the national average.The growth rate is slower in the east side of the HU Huanyong Line than that in the west side,the absolute gap of income widens between the east side of the HU Huanyong Line and the west.The growth rate is faster in the south side of the Qinhuai Line than that in the north side,which leads to a shift from'higher in the north side of the Qinhuai Line'to'lower in the north side of the Qinhuai Line.2)The differences in residents'income level decreases but the income gap is still significant.The income differences mainly present at the obvious shift from the county scale to both county and functional area scales.The income differences at regional scale are mainly manifested in respective intraregional differences,and the differences among regions are mainly among the west China and other regions.3)The spatial characteristics and change trend of residents'income level are similar at county and functional area scales,the trend surface of income changes is not obvious in the middle of China and the west of China,but it has obvious changes in the east of China and the northeast of China.4)The driving factors of residents'income tend to be diversified and their role has generally enhanced.Urbanization,population scale,agricultural development and local public finance are important driving factors of the residents'income level,and economic development mainly affects residents'income through the transmission mechanism.Finally,some suggestions are given to improve residents'income,such as accelerating urbanization,promoting green development,enhancing employment,optimizing the use of financial funds,and implementing differentiated policies.
