城镇化、金融发展与城乡统筹关系研究

通过构建指标体系,采用1991年至2010年的数据,对我国城镇化、金融发展与城乡统筹的关系进行了实证研究。采用主成份分析法形成城乡统筹水平、城镇化水平和金融发展水平变量综合数值,通过序列平稳性检验、格兰杰因果关系检验、相关分析等方法对问题假设进行了验证。研究结果表明:城镇化是金融发展的格兰杰原因,二者之间存在显著的正相关关系;城镇化与城乡统筹、金融发展与城乡统筹之间都不存在格兰杰因果关系,城镇化与金融发展并不必然导致城乡统筹水平的提高。     

互联网普及对城乡居民收入差距影响研究——基于VAR模型的实证分析

为了研究我国互联网普及对城乡居民收入差距的影响,本文基于2005-2018年的时间序列数据,通过建立VAR模型,运用单位根检验、协整检验、格兰杰因果检验、脉冲响应分析和方差分解等方法研究了互联网普及与城乡收入差距的动态关系.结果表明:在短期内,互联网普及与城乡收入差距存在双向格兰杰因果关系,互联网普及对城乡收入差距具有一定影响,但影响的方向具有不确定性;从长期看,互联网普及对城乡收入差距具有负向促进作用,并保持着稳定均衡关系,互联网普及率对城乡收入差距预测方差具有较大贡献度.对此,文章提出加大农村互联网资金投入力度、加强农村基础设施建设、提高农村互联网金融发展力度等建议,以缩小城乡收入差距.     

对我国CPI与PPI关系研究——基于季节调整后的数据分析

选取1997年1月～2011年12月间我国月度CPI和PPI数据进行了定基处理和季节调整,然后在其基础上建立了VAR模型。该模型分析的结果表明CPI和PPI之间存在协整关系。格兰杰因果检验分析结果表明,在5%的显著性水平下,CPI与PPI互为格兰杰因果。方差分解的结果表明,CPI和PPI自己对自己的变化的贡献率比较大。     

中国教育发展对经济增长贡献率水平的实证分析

教育发展将促进经济的增长,反之,经济的发展也必然要求教育的提高。文章通过格兰杰因果检验,分析教育与经济发展之间的因果关系,在此基础上,建立教育发展的生产函数模型,计算出不同教育程度的劳动力对经济增长的贡献率及教育整体发展对经济发展的贡献水平,从而提出应该加强以基础教育为主,同时注重对高等教育投入的观点。     

我国服务价格与物价总水平波动互动关系研究

通过采用1992～2011年全国居民消费价格总水平、服务价格上涨率时间序列数据,建立VAR模型,运用脉冲响应函数和预测方差分解的方法对服务价格波动和我国物价总水平波动互动关系进行实证研究。计量结果表明,服务价格波动与我国物价总水平波动间存在单向因果关系,服务价格波动是我国物价总水平波动的格兰杰原因。服务价格波动1%,会带来物价总水平0.5902%的波动。VAR模型的动态分析表明,服务价格波动对我国物价总水平波动约有5年的影响。方差分解的结果说明服务价格波动对我国物价总水平波动的贡献率最大达到38.4%。要防止我国物价总水平大幅度波动,政府需要更加重视产业价格政策。     

城乡统筹发展视角下湖南省城乡协调发展评价

在回顾国内外城乡统筹发展理论的基础上,运用主成分分析法和格兰杰因果分析模型构建了城乡协调发展评价模型,以湖南省1995—2012年年度数据为实证材料,分析了湖南省城乡协调发展水平,结果表明:城乡统筹度与城乡收入差距之间存在双向的因果关系,为进一步促进湖南省城乡统筹、协调发展,有必要立足于经济社会全面发展的角度,遵循城乡发展的客观规律和现实需要,建立和完善城乡一体化发展的体制机制,促进农村与城市同步并进、协调发展。     

宁夏回族聚集区乡村发展对城镇化的响应及空间特征

以宁夏回族聚集区为例,对2007—2015年乡村发展水平指数和城镇化水平指数测度的基础上,利用格兰杰因果检验、脉冲响应函数及方差分解模型,计量分析了乡村发展对城镇化的响应程度。结果表明:(1)2007年以来,宁夏回族聚集区乡村发展水平与城镇化水平经历了非同步发展的演变过程;(2)乡村发展水平及其子项农业生产水平、农户生活水平和农村经济水平分别与城镇化互为格兰杰因果关系,但是对城镇化的响应程度存在显著差异性;(3)经济发展状况越好的地区,乡村发展水平、农村经济水平越容易受城镇化的影响,而农业生产水平却相反,经济发展状况越低的地区越容易受影响,农户生活水平普遍受城镇化影响较大。     

教育对西部地区农村经济影响的实证研究——以统筹城乡综合配套改革实验区重庆为例

为反映教育与西部地区农村经济发展的关系,本文选择统筹城乡综合配套改革实验区重庆的实际数据,运用灰色关联分析测算教育与农村经济的关联度,然后利用Mincer模型计算教育对农村经济的产出弹性,最后利用复杂劳动简化系数法测算教育时农村经济的贡献率.实证分析的结果表明:教育与农村经济关联度较大,仅次于资本要素;教育对农村经济的产出弹性较显著;教育对农村经济的贡献较大.教育发展可以成为统筹城乡发展、缩小城乡差距的重要手段.     

空气污染程度与经济发展水平对人口死亡率的影响研究——基于向量自回归模型的实证分析

利用1983—2015年的时间序列数据,构建计量实证模型,采用协整分析和向量自回归等分析方法,实证研究人口死亡率、空气污染程度与经济发展水平之间的协整关系、格兰杰因果关系、脉冲效应以及方差分解,以探析空气污染程度与经济发展水平对人口死亡率的影响。研究发现:空气污染程度上升会导致人口死亡率增加,而提高经济发展水平则会降低人口死亡率,人口死亡率、空气污染程度与经济发展水平之间存在长期稳定的协整关系;人口死亡率、空气污染程度与经济发展水平之间存在单项的格兰杰因果关系,即空气污染程度与经济发展水平是人口死亡率的格兰杰成因;从脉冲效应和方差分解得出,空气污染程度的变动对人口死亡率产生较大的正作用,而经济发展水平的变动对人口死亡率产生较小的副作用。     

河北省信息产业对经济增长的间接贡献度测量分析

在采用关联度及格兰杰因果关系检验来验证信息产业与三大产业之间的关联性的基础上,建立中性技术进步假设下修正的柯布—道格拉斯生产函数,测量信息产业对河北省三大产业的间接贡献度,结果表明:河北省信息产业与服务业有较强的关联度,并且互为发展的因果关系,但与农业的关联水平较低。河北省发展信息产业应依托产业集聚度,充分发挥信息产业集聚效应,加强信息人才培养。

What would happen if terrorists took down the bridge between San Francisco and Marin County? How much of the region would be affected and for how long?     

John Stuart Mill's Theory Of Justice

John Stuart Mill has traditionally been portrayed as self-contradictory and failing to construct a unified social theory. Recent scholarship, however, has challenged this view, finding Mill's work to be creatively synthetic in bridging the antinomies inherent in liberal democratic thought. This revisionist interpretation of Mill is advanced by an understanding of his theory of justice and its role in shaping his policy positions on issues such as welfare, education, voting rights, property rights, taxation, government intervention, and the future of capitalism.

John Stuart Mill's Theories of Wealth and Income Distribution

Although he was much influenced by David Ricardo when he wrote the classical part of his Principles , John Stuart Mill was not a Ricardian when he penned his theories of wealth and distribution. They are based on a triple foundation. First, a belief that economics is a moral discipline. Second a theory of custom-driven human behavior. Third, an empirically formed conviction that the institutions of state, education and business cooperate to structure the distribution of income. On the basis of these presuppositions, Mill formulated 1) an institutional theory of the formation of human and non-human wealth and 2) an even more institutional theory of distribution demonstrating how the aforementioned institutions malignantly skew the distribution of income to the advantage of the propertied classes and to the extreme disadvantage of the working class. As a social economist, Mill recommended institutional reforms designed to eradicate the poverty of the working class.     

Toward a Phylogenetic Reconstruction of Organizational Life

Synopsis Classification is an important activity that facilitates theory development in many academic disciplines. Scholars in fields such as organizational science, management science and economics and have long recognized that classification offers an approach for ordering and understanding the diversity of organizational taxa (groups of one or more similar organizational entities). However, even the most prominent organizational classifications have limited utility, as they tend to be shaped by a specific research bias, inadequate units of analysis and a standard neoclassical economic view that does not naturally accommodate the disequilibrium dynamics of modern competition. The result is a relatively large number of individual and unconnected organizational classifications, which tend to ignore the processes of change responsible for organizational diversity. Collectively they fail to provide any sort of universal system for ordering, compiling and presenting knowledge on organizational diversity. This paper has two purposes. First, it reviews the general status of the major theoretical approaches to biological and organizational classification and compares the methods and resulting classifications derived from each approach. Definitions of key terms and a discussion on the three principal schools of biological classification (evolutionary systematics, phenetics and cladistics) are included in this review. Second, this paper aims to encourage critical thinking and debate about the use of the cladistic classification approach for inferring and representing the historical relationships underpinning organizational diversity. This involves examining the feasibility of applying the logic of common ancestry to populations of organizations. Consequently, this paper is exploratory and preparatory in style, with illustrations and assertions concerning the study and classification of organizational diversity.     

Information infrastructure: Who builds broadband networks?

This paper examines the essential difference between the U.S. and Japan, when one considers information infrastructure. There are seven perception gaps between the U.S. and Japan concerning Information Infrastructure policies. These gaps must be understood in order to compare the countries' governmental policies in this area. In looking at the present circumstances, the essential question to answer concerns who is to build, own and operate the network(s) of the infrastructure. Liberalization is certain to be a central factor in the ongoing telecommunications debates. Now that customers have had a taste of the liberalized market-place, the movement toward more open markets will be difficult to stop. When considering options, it is necessary to pay close attention to standardized network access and the increasingly important role software plays. These issues are causing us to take a new approach to the traditional role played by regulators. They also force a closer look at the appropriate structure of utility companies. This paper addresses the above issues in hopes of stimulating dialog on the new telecommunications infrastructure paradigm.

海岛地区产业演替及资源基础分析--以舟山群岛为例

改革开放以来,舟山市产业构成发生了显著变化,其经济发展过程可以划分为三个阶段。1992年前,是以产业结构渔业占绝对地位的单一结构阶段;1993—1998年,以旅游业为主的第三产业快速发展阶段;上世纪末以来,又进入了新一轮的经济发展时期,即工业产值比重快速增加阶段。根据海岛的自然资源基础和特点,在新世纪的经济发展过程中,舟山市应定位为生态型的港口旅游城市。以港口及临港工业为主导,以海岛旅游和海洋经济为特色,大力发展第二产业和第三产业。海岛地区的主导产业应体现海岛资源优势及区位优势,以集群性环保型产业为主。同时由于海岛地区淡水资源缺乏,主导产业也应着重选择低耗水型产业。
