Time-varying linkages between tourism receipts and economic growth in South Africa

The causal link between tourism receipts and GDP has recently become a major focus in the tourism economics literature. Results obtained in recent studies about the causal link appear to be sensitive with respect to the countries analysed, sample period and methodology employed. Considering the sensitivity of the causal link, we use rolling window and time-varying coefficient estimation methods to analyse the parameter stability and Granger causality based on a vector error correction model (VECM). When applied to South Africa for the period 1960–2011, the findings are as follows: results from the full-sample VECM indicate that there is no Granger causality between tourism receipts and GDP, while the findings from the time-varying coefficients model based on the state-space representation show that tourism receipts have positive-predictive content for GDP for the entire period, with the exception of the period between 1985 and 1990. Full-sample time-varying causality tests show bidirectional strong causality between tourism receipts and GDP.

Im übrigen wird auf das Gesetz über Krankenkassen hingewiesen.     

Cities, hinterlands and agglomeration shadows: Spatial developments in Finland during 1880–2004

This paper analyzes long-term spatial developments in Finland by focusing on two predictions of the new economic geography (NEG) models: the increasing persistence of locational patterns and the rising dominance of growth centers. The empirical analysis is based on regional population data from 1880 to 2004. The results support the hypotheses. Evolutions in rank and rank-size distributions during the processes of industrialization and urbanization suggest increasing persistence of regional structures. The analysis of causal processes between population centers and their hinterlands shows that these regions grew hand-in-hand in the pre-war period, whereas agglomeration shadows started to come about during the post-war period.     

区域金融发展与经济增长的实证研究——以江苏省为例

本文首先说明金融部门促进经济增长的内在机制的内生增长模型。在实证研究部分,本文改变以往研究中使用国际通用指标的做法,针对我国经济转型和银行主导金融体系的特点,使用了符合实际的经济增长指标和金融发展指标。在考虑变量的平稳性之后,模型通过了自相关检验,最后,由格兰杰检验来探讨金融发展与经济增长的因果关系,结果表明金融发展与经济增长之间存在双向因果关系。     

Trade‐led growth hypothesis in Cuban commercial regimes since 19601,2

This study examines the impact of trade on Cuban growth during different commercial policy regimes spanning the period from 1960 up to 2004, encompassing two essential economic structural transformations: the Cuban revolution and the fall of the Berlin Wall. For this purpose, the Granger causality is used by means of the modified Wald test for augmented‐level vector autoregressive model with integrated and cointegrated processes introduced by Toda and Yamamoto (1995) and Dolado and Lutekepohl (1996) . We show an import‐led growth hypothesis during the Soviet‐oriented pattern that is rejected after 1990, when exports are not only responsive to growth expansion but also to imports’ behaviour.     

论中国经济长周期波动的特殊性

本文的分析表明，技术创新和制度创新是长波运行的主要动力。中国经济长波存在超长的上升期，这一特殊性源自我国技术创新和制度创新的不断进展。我们应继续以持续的技术创新和制度创新来推动我国经济长波的高位平稳运行。     

新疆对外贸易与经济增长的实证分析

本文根据新疆1990年-2005年的统计数据,利用协整理论和格兰杰(Granger)因果关系检验对新疆国内生产总值、投资和进出口贸易之间的关系进行分析。结果表明新疆国内生产总值与投资及进出口之间存在长期稳定的关系,投资和出口增长是拉动经济增长的原因,而经济增长却不是拉动投资、进出口增长的原因。     

对我国区际经济与金融差距关联性的实证分析

各区域间金融发展的差异对经济发展差距有无影响以及影响机制如何成为经济学研究的一项任务。以塞尔指标衡量我国经济与金融发展差距,发现我国区域间经济发展差距与金融发展差距呈现一致的变动关系,且金融差距大于经济差距。由此引出的基本判断是我国区际经济差距的逻辑原因有金融因素,进而采用格兰杰因果关系检验判断我国省际金融发展与经济增长间的关系,从中可以明确我国东部地区金融成长偏重于内生状态,而中西部地区更倾向于外生状态。考虑到改革的总体方向,并借鉴东部地区的经验,放松金融抑制、催化内生金融成长无疑是全面促进中西部经济发展的必然选择。     

黑龙江省耕地非农化与经济发展的Granger因果关系研究

研究目的:分析黑龙江省耕地非农化过程的内在原因,以助于协调黑龙江省耕地非农化进程与经济发展的关系,使耕地保护工作与未来经济运行相一致。研究方法:运用Granger因果关系检验法,利用Eviews4.1软件分析。研究结果:城市化进程对耕地非农化进程的影响与经济增长对耕地非农化的影响并不一致,城市化进程对耕地非农化的影响更加显著。因此,要从根本上解决耕地非农化与经济发展之间的矛盾须将城市化作为切入点。
