清洁发展机制项目省际面板数据实证研究

中国目前已经成为签订京都议定书以来实施清洁发展机制项目数量最多的东道国,之前的研究文献鲜有对省级清洁发展机制项目分布的内在机理进行分析。考虑到中国具体的政治、经济、地理多样性背景,本文通过对2004~2011年已经审批通过的所有清洁发展机制项目数量变量及相关解释变量的变截距固定效应面板检验,发现各省份的电力消费水平、经济发达程度、外资流入水平在很大程度上影响着清洁发展机制项目的布局。研究结果发现清洁发展机制项目主办方更多考虑到减排项目的经济效益,从而将清洁发展机制项目选择落户在电力消费水平较高、人均国内生产总值较低、外资流入不太积极的省份地区,间接说明发展清洁机制项目对于缩小经济发达省份与欠发达省份经济差距,改善中西部基础设施建设有正向积极作用。

社会资本与经济增长的正相关作用浅析

对经济增长影响因素的研究历来是经济学文献中的重要组成部分,但主流经济学大多忽视了非经济因素,特别是社会资本对于经济增长的作用。该文在文献回顾的基础上概括出社会资本影响宏观经济增长可能存在的作用机制,并指出成本内部化和收益外部化的正外部性是社会资本影响经济增长的根本性原因。同时通过对我国目前社会资本与经济增长相关性研究的分析,发现研究结论虽然能说明正相关作用性,但存在数据上可靠的理论依据,进而发现该研究思路及研究方向上可能存在的问题。

Spatial Distribution of Integrated Impact Index of Mega-event——A Case Study of Expo '99 Kunming

Taking the affinity between events and media as a conceptualization base, a total of 1032 related news re-ports of Expo '99 Kunming, gathered from the internet data bank of China INFOBANK from 1992 to 2003, are used as data sources. After classifying them with a communication research method-the content analysis, a data bank for SPSS is set up, and a mathematic model called the Integrated Impact Index of Expo '99 Kunming is constituted. With the model, the spatial distribution of the total integrated impacts of Expo '99 Kunming on the regions or cities with different regional scales is analysed quantitatively. The conclusions are: 1) the Expo '99 Kunming made obvious integrated impacts on the regions or cities of every scale, especially in the venue city and the region-Kunming City and Yunnan Province; 2) it had corresponding impacts on other provinces; 3) the spatial distribution of Integrated Impact Index had a disaggregation with both plane extension and spotted decentralization; and 4) there was a distance decay law in all three scales of regions (Kunming City, Yunnan Province and the whole China), which incarnated the spatial extension law of the integrated impact of a special mega-event.

Changing Rural Development Inequality in Jilin Province, Northeast China

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.
