区域消费水平是经济发展的重要动力。本文以1978-2011年间我国各省区的人均消费品零售额表征区域消费水平,在我国区域消费水平差异测度的基础上,对区域消费水平差异的时间序列值进行突变点检测,进而将我国区域消费水平变化划分为1978-1986年和1986-2011年2个阶段。通过利用传统马尔科夫链及空间马尔科夫链方法,分别构建人均消费水平的非空间和空间马尔科夫转移概率矩阵,对1978-1986年与1986-2011年2个阶段的区域消费水平的时空格局演变特征进行分析。研究结果表明:(1)区域消费水平在2个研究时段内的变化均存在着“俱乐部趋同”现象,无论是低消费水平与高消费水平区域均沿着最初类型稳步演进。(2)区域消费水平变化受到来自邻域消费水平背景的影响,使得其趋同的过程在空间上不独立。(3)区域间消费水平相互作用呈现出显著的东西分异特征,东部地区多为区域自身消费水平与邻域消费水平同时向上转移的状态,西部地区多为向下转移的状态,而中部地区多为平稳分布,邻域消费水平的状态变化较大。  相似文献

京津冀都市区经济增长空间分异的GIS分析   总被引:2,自引:0,他引:2  
基于GIS技术和探索性空间数据分析(ESDA)方法,利用京津冀都市区1995-2007年人均GDP数据,对京津冀都市区经济发展水平、经济增长率及其和初始发展水平动态关系进行了深入的研究。研究表明:(1)京津冀都市区经济差异和空间集聚都呈逐步扩大趋势,空间依赖增强,经济差异和空间集聚呈较高的正相关关系,京津冀都市区经济发展水平空间集聚的增加,在一定程度上加大了经济差异。(2)京津冀都市区内部形成了两大空间集聚区,一个以北京、天津、唐山为核心的高经济发展水平的集聚区;另一个是以承德、张家口和保定为核心的低经济发展水平的集聚区。(3)初始经济发展水平局部空间自相关类型不同的区域,经济增长率与初始发展水平的动态关系不同,初始发展水平高的空间集聚区表现出明显的经济收敛性,而初始发展水平低的空间集聚区中的多数地区则有落入"恶性循环累积陷阱"的倾向。  相似文献

区域人口迁移流的规模不仅取决于迁出地与目的地的“双边”要素,也与前期迁移流和周边迁移流息息相关。传统重力模型揭示了区域人口迁移过程的“推-拉”机制,但受制于对时空维度的忽视,无法有效表达迁移流之间的时空依赖关系,因而难以度量区域要素变化对迁移流产生的时空溢出效应。本文引入多种形式的时空依赖结构,构建迁移流时空重力模型,并采用贝叶斯马尔可夫链蒙特卡洛(MCMC)方法进行估计。在此基础上,结合时空效应框架量化区域要素对迁移流的影响,定量分析人口迁移过程的时空溢出效应与动力机制。本文以1985-2015年中国省际人口迁移为例,通过与非空间的动态重力模型估计结果比较,初步表明时间依赖、空间依赖以及时空扩散依赖在区域人口迁移过程中不容忽视;时空维度上,区域要素变化在初期对迁移网络的溢出效应超过对该区域迁移流的直接影响;逐渐衰减的时空溢出效应维持了区域人口迁移规模发展的相对稳定,与动态重力模型估计结果形成了鲜明对比。区域人口规模、人均GDP水平及其时空溢出效应共同驱动中国省际人口迁移系统的发展。耦合时空维度依赖关系的时空重力模型能更好地理解区域人口迁移过程的演化特征,为促进区域人口均衡发展提供科学的决策依据。  相似文献

Regional disparity and convergence of China’s inbound tourism economy   总被引:1,自引:0,他引:1  
Comprehending regional characteristics and influencing factors of China’s inbound tourism economy is important to make effective policies that will help inbound tourism develop harmoniously and shrink regional disparity. This paper studied the regional disparity and convergence of China’s inbound tourism economy during 1996–2008 with the methods of σ-convergence, club convergence and β-convergence. The results indicate that 1) inbound tourism receipts per capita (ITRPC) of the whole country, the eastern, central and western regions presented the rapid increasing trend; 2) ITRPC of the whole country was characterized by convergence; 3) the eastern region presented club convergence, but the central and western regions did not show this trend; 4) the star-hotel levels and investment in fixed assets for the tourism industry per capita had a same trend to growth rates of ITRPC, promoting inbound tourism development, and there was no difference among the 31 provinces (municipalities) in the mainland of China; 5) but the proportion of employed persons in the tourism industry accounting for total population and the proportion of the tertiary industry accounting for GDP had a reversal trend to growth rates of ITRPC, shrinking the provincial disparity in inbound tourism economy, and there were differences between the developed provinces and the developing provinces. Based on these analyses, we put forward some suggestions for the developing provinces to speed up inbound tourism economy.  相似文献

While China‘s economic growth has been impressive since 1978, regional disparity in terms of provincial per capita GDP has been increasing. On the other hand, this rapid but uneven growth was accompanied by China‘s deepening openness and structural reforms including the development of non-state-owned enterprises (non-SOEs) and fiscal decentralization. Based on quantitative analyses, this paper tries to explore the features of regional disparity in China and the relationships between regional growth and China‘s openness and economic structure reforms in the period from 1981 to 2000, The paper finds that the catching-up of the coastal region to the initially rich provinces, which are mainly located in inland areas, brought about a convergence of the growth pattern across provinces in the 1980s. The subsequent divergence in the provincial growth rates between the coast and the interior generated an enlarging regional disparity in China in the 1990s. The ever-faster growth in the coastal region was benefited by China‘s openness and the development of non-state-owned enterprises. The development of non-state-owned enterprises underlies the higher operational efficiency in the coastal region. Additionally, with the insignificant regression results, fiscal decentralization was observed to facilitate faster growth in the coast region. The findings justify the initiative of the “West Region Development Strategy“ and offer some policy implications for China.  相似文献

Measuring the economic and social effects of the Northeast China Revitalization Strategy is critical to addressing regional sustainable development in China. To shed light on this issue, an integrated perspective was adopted that is combined with the difference-in-differences method to measure the effects of the strategy on economic growth and social development in Northeast China. The findings suggest that the strategy has significantly improved regional economic growth and per-capita income by increasing its gross domestic product(GDP) and GDP per capita by 25.70% and 46.00%, respectively. However, the strategy has significantly worsened the regional employment in the secondary industry of the region. In addition, the strategy has not significantly improved regional infrastructural road, education investment or social security, and has had no significant effect on mitigating regional disparity. In addition, the policy effects are highly heterogeneous across cities based on city size and characteristics. Therefore, there is no simple answer regarding whether the Northeast China Revitalization Strategy has reached its original goals from an integrated perspective. The next phase of the strategy should emphasize improving research and development(RD) and human capital investments based on urban heterogeneity to prevent conservative path-dependency and the lock-in of outdated technologies.  相似文献

Social assistance is the last safety net in the social security system and plays a vital role in poverty alleviation in countries around the world. Promoting the equal financial assistance is meaningful to achieve equalization of social assistance. Based on the provincial panel data from 2002 to 2017, this paper analyzes the dynamic characteristics and main influencing factors of the equity of social assistance in China, using the Theil index and geographically weighted regression(GWR) model.

In order to clarify regional ecological security status and formation mechanism of regional ecological security barriers in underdeveloped regions of China, we took Yunnan province as a case to evaluate its regional ecological security by using entropy matter-element model, comprehensive index and GIS spatial method, and we diagnosed its obstacle factors through obstacle degree model. We found a low overall level of regional ecological security in Yunnan. Only Kunming fell into the good level, 68% of the regions were below the critical safe level. For the vast majority of regions in Yunnan, their regional ecological security was unstable. The indexes related to per capita resources, geological and topography environment, economic, and technology were at the unsafe or dangerous level. The indexes related to urban expansion, level of income, cultivated land quality were at the level of critical safety. The indexes concerning urban management capacity, air quality and water environment were at the good or ideal level. Yunnan’s regional ecological security was not good due to natural obstructive environment itself, simultaneously lower backward economic and social level restricted the ability of ecological security response to manage ragile ecological environment. The results of the composite index were roughly consistent with those of the entropy weight matter-element model. The mean values of the classification index, from high to low, were: the state index > the response index > the pressure index. The state index and the response index had a significant mutual promotion to each other. The regions with good composite index, state index and response index mainly distributed in the central regions of Yunnan Province. Spatial autocorrelation of regional ecological security level in Yunnan was not obvious. Water resources, economic and social development were main obstacle factors of the regional ecological security. When distinguishing with obstacle type, Kunming belonged to natural ecological environment barrier type, while other regions belonged to economic and social barrier type.  相似文献

Rapid urbanization in China has led to an increasing imbalance in regional development. The Guangxi Zhuang Autonomous Region, a less developed border region with unique cultural diversity, has a relatively large population(4.52 million people in 2015) under the poverty line, according to the national standard of poverty. China has launched a national campaign to reduce poverty using a wide range of new development policies and large-scale investment. However, there have been few studies on the determinants of poverty at the county level across a province. This paper aims to explore the spatial and social differences related to poverty among 109 counties by considering the spatial heterogeneity of poverty determinants. Spatial statistical models revealed that slope(Slp), GDP per capita(GDPP), the ethnic minority population ratio(EMPR), medical and technical personnel of healthcare institutions(MTP) and illiteracy rate(IR) significantly affect the patterns of the poverty rate, with a high adjusted R2(0.67), while the poverty rate affects GDPP, IR, MTP and EMPR; i.e., the effects are interactional. Furthermore, the IR is significantly affected by the provision of schools and transportation conditions. Among these determinants, social factors may be key. The spatial patterns of these relationships demonstrate remarkable variation across the province and between minor and major groups. This quantitative evidence is enhanced by indepth interviews with selected groups. These results are expected to be useful for the anti-poverty project in Guangxi.  相似文献

Shift-share analysis has been confirmed a useful approach in the study of regional economics and many kinds of extended shift-share models have been advanced and put into practice in economic studies, but few have hitherto been introduced and applied to the tourism research in China. Moreover understanding the spatially competitive relationship is of paramount importance for marketers, developers, and planners involved in tourism strategy development. Based on international tourism receipts from 1995 to 2004, this study aims at probing into the spatial competitiveness of interna- tional tourism in Jiangsu Province in comparison with its neighbors by applying a spatially extended shift-share model and a modified dynamic shift-share model. The empirical results illustrate that exceptional years may exist in the ap- plication of dynamic shift-share models. To solve this issue, modifications to dynamic shift-share model are put forward. The analytical results are not only presented but also explained by the comparison of background conditions of tourism development between Jiangsu and its key competitors. The conclusions can be drawn that the growth of international tourism receipts in Jiangsu mainly attributes to the national component and the competitive component and Zhejiang is the most important rival to Jiangsu during the period of 1995-2004. In order to upgrade the tourism competitiveness, it is indispensable for Jiangsu to take proper positioning, promoting and marketing strategies and to cooperate and integrate with its main rivals.  相似文献

The economic growth of China has led to increasing growth disparities between regions. Such disparities are uncontrolled and are severely negative symptoms in the process of economic development. On the basis of system dynamics (SD) modeling and the rela- tionship between industrial relocation and regional economic growth, we construct a model of the interrelationship between the two aforementioned phenomena. The model is an effective and creative exploration for examining effects of industrial relocation on Chinese regional economic growth disparities. The SD model is employed in this study to build an inter-regional labor migration SD model, an inter-regional capital migration SD model, an intra-industry SD model, an intra-regional population SD model, and an intra-regional SD model which are based on realities in labor and capital flow from the view of industrial relocation. VENSIM software is utilized to per- form a system simulation based on the data of the eastern, middle, and western regions from 2000 to 2010. Results show that indus- trial relocation gradually narrows the relative disparity in GDP among the three regions. Moreover, the absolute one is enlarged con- tinuously. The absolute and relative disparities in per capita GDP among eastern, middle, and western regions generally exhibit de- creasing trends.  相似文献

In this study, an inventory analysis approach was used to investigate the intensity of agricultural non-point source pollution(ANSP) and its spatial convergence at national and provincial levels in China from 1999 to 2017. On this basis, spatial factors affecting ANSP were explored by constructing a spatial econometric model. The results indicate that: 1) The intensity of China’s ANSP emission showed an overall upward trend and an obvious spatial difference, with the values being high in the eas...  相似文献
