许多人都相信我国省区经济差距与制度变迁(渐进改革)有关,但为制度内生性等问题所困,严谨的实证分析并不多见。本文尝试实证分析各省区内生的社会基础设施(由制度、政策等构成)的差异在省区经济差距中的作用。具体而言,我们找到... 许多人都相信我国省区经济差距与制度变迁(渐进改革)有关,但为制度内生性等问题所困,严谨的实证分析并不多见。本文尝试实证分析各省区内生的社会基础设施(由制度、政策等构成)的差异在省区经济差距中的作用。具体而言,我们找到了反映各省区历史上曾拥有的发展市场经济软环境的数据,并视其为工具变量,从而把各省区当今的社会基础设施内生,结果发现,各省区经济绩效的差异可稳健地归因于其内生的社会基础设施的差异。 展开更多

Rural development inequality is an important practical issue during the course of full establishment of a ′moderately well-off society′ in modern China,and the objective understanding and evaluation of the status and regional inequality of rural development can provide scientific basis for ′building a new countryside′ and coordination development of rural-urban regions.Based on the county-level data of 2000,2005 and 2009,this paper examines the rural development inequality of Jilin Province in Northeast China by establishing a rural development index.The spatio-temporal dynamic patterns and domain factors are discussed by using the method of exploratory spatial data analysis and multi-regression model.The results are shown as follows.Firstly,most of the counties were in lower development level,which accounted for 58.3%,62.5% and 66.7% of the total counties in 2000,2005 and 2009,respectively.The characteristics of spatial inequality were very obvious at county level.For example,rural development level of Changchun Proper and the proper of seven prefecture-level cities were much higher than that of the surrounding regions.The counties in the eastern and northern Jilin Province were the lowest regions of rural development level,while the middle counties were the rapid growth areas in rural economy.Secondly,Moran′s I of rural development index(RDI) was 0.01,–0.16 and –0.06 in 2000,2005 and 2009,respectively,which indicated that spatial agglomeration of RDI was not obvious in Jilin Province,and took on the characteristic of random distribution.The counties of both the units and its adjacent units have higher development level(HH) were transferred from the western areas to the eastern areas,while the countries of both the units and its adjacent units have lower development level(LL) were diffused from the eastern to middle and western Jilin Province.Finally,the result of multi-regression analysis showed that the improvement of agricultural production condition,development of agricultural economics and the adjustment of industrial structure were the domain factors affecting rural development inequality of Jilin Province in the later ten years. 展开更多

本文建立了空间不平等的动态演进模型(DEMSI模型),并对模型结果进行数值模拟,从理论上论证了空间不平等与经济发展之间的倒"U"型关系的存在。同时,本文基于1978-2012年中国的省际面板数据,分别使用半参数面板固定效应模型和... 本文建立了空间不平等的动态演进模型(DEMSI模型),并对模型结果进行数值模拟,从理论上论证了空间不平等与经济发展之间的倒"U"型关系的存在。同时,本文基于1978-2012年中国的省际面板数据,分别使用半参数面板固定效应模型和参数面板固定效应模型实证检验了空间不平等与中国经济发展之间的关系。研究结果表明:在控制了其它解释变量后,1978年以来,空间不平等与中国经济发展存在明显的"W"型关系,而非简单的倒"U"型关系。最后,本文就研究的结论提出了相应的政策建议。 展开更多
