重庆市乡村旅游资源空间特征及其与乡村振兴关系研究

[目的]探究重庆市乡村旅游资源的结构类型和空间特征,分析乡村旅游资源数量与乡村振兴之间的关系,对重庆市乡村旅游产业发展和促进乡村振兴具有指导意义。[方法]文章利用GIS技术定量分析重庆市乡村旅游资源的空间分布特征,通过空间分布模型探究乡村旅游资源空间分布的聚集程度,利用地理联系率探析人口规模和经济发展水平与乡村旅游资源分布的配合度。采用回归模型从整体上对重庆市乡村旅游资源数量与乡村振兴的关系进行分析,利用Pearson相关系数对不同经济发展区域关系进行研究,试图得到乡村旅游资源数量与乡村振兴的辩证关系。[结果]重庆市乡村旅游资源具有4种类型,农事体验类所占的比重最大,达到43.46%,乡村文化类所占比重最低为2.30%。乡村旅游空间布局特征结果表明重庆市4种乡村旅游类型在空间上的分布存在较大的区域差异,都呈现集中分布, 4种类型的景点与人口和经济的配合度较高。回归分析结果表明,乡村旅游资源数量与休闲农业和乡村旅游接待人次、农村卫生厕所普及率、村综合性文化服务中心覆盖率、县级以上文明村和乡镇占比和农村居民人均纯收入之间存在均衡关系。Pearson相关性分析结果表明除休闲农业和乡村旅游接待人次外,乡村旅游资源数量仅与农村居民人均纯收入之间存在低度相关性,不同经济区相关系数差异较大。[结论]综合以上研究结果,乡村旅游资源的空间分布特征既受当地经济发展的影响,同时又促进当地经济的发展,表明重庆市乡村旅游资源对乡村振兴具有一定的促进作用。建议在今后的发展中应拓展乡村旅游类型,提高乡村文化类景点的数量和比重,促进重庆市乡村旅游产业的均衡发展,实现不同经济区乡村经济的协调发展。     

Effects of Firm Size,Financial Leverage and R&D Expenditures on Firm Earnings: An Analysis Using Quantile Regression Approach

As documented in the literature, the effects of firm size, financial leverage, and R&D expenditures on firm earnings are inclusive. Our hypothesis is that the inconsistent empirical results of such effects may be driven by the regression models implemented in data analysis. Using the quantile regression (QR) approach developed by Koenker and Basset (1978), this study analyses S&P 500 firms from 1996 to 2005. We find that the effects of firm size, financial leverage and R&D expenditures on firm earnings differ considerably across earnings quantiles. Comparing the results from the QR approach with those from the ordinary least squares (OLS) and least absolute deviation (LAD) methods, this study further explains the puzzling relationship between firm size, financial leverage, R&D expenditures and firm earnings.     

How credible is inflation targeting in Asia? A quantile unit root perspective

This article examines the dynamic behavior of the inflation rate for eight Asian countries using a quantile unit root test. We advocate a three-way definition of inflation targeting based on perfect, imperfect and zero credibility and advance the analysis by incorporating a fully-fledged adoption of inflation targeting. In doing so, we offer new insights by showing that the credibility of inflation targeting and the alternative monetary policy frameworks in Asia are imperfect, except for Malaysia and South Korea under a fully-fledged adoption of inflation targeting. In contrast to past studies that focus on the mean-reversion in inflation rates, we also consider trend-reversion and find that Asian inflation targeting countries have been building up their monetary policy credibility more than the non- inflation targeting countries in terms of a faster rate of decline in inflation rate changes. Our results generally indicate the presence of mean reversion at the lower quantiles only. Where stationarity is present, we find evidence of a varied speed of adjustment process across the quantiles. Finally, we determine the threshold levels whereby inflation becomes stationary and demonstrate that Asian inflation rates generally display stationary behavior during periods of inflation declining or slowing down.     

制度创新与经济增长——一个理论分析框架及实证检验

任何经济增长过程都是在一定的制度环境中进行的，有必要将制度因素纳入经济增长理论当中。在新古典经济学框架下，本文通过理论模型分析，认为稳态下的经济增长率跟制度创新有着紧密的正向关的关系。在理论分析的基础上，本文基于1978～2012年的省际面板数据，利用半参数估计和线性回归估计方法，实证分析结果表明：国家财政干预的增强、国有经济的强化和垄断作用加强从整体上抑制了我国以及不同地区的经济增长，提高市场开放度和对产权的保护程度则对经济增长产生了积极的正向促进作用，制度差异是引起我国区域经济增长差异的重要因素之一，制度创新仍是当前我国经济增长的关键。     

农业农村双创工作的成效机制研究

[目的]近年来,创新创业的热潮大力兴起,如何对农民双创工作的成效机制进行研究,成为文章研究的重点。通过对农民双创工作中的创业者特征、创业者关系、政策适应与农业农村双创收益机理的研究,找出创业企业绩效演变机理。[方法]收集2017年2—5月重庆24个地区1 855位农民的调查问卷,采用专家评价法对双创收益、创业培训、创业者社会关系和创业政策适应的测量项目进行因子分析。[结果]对农民双创收益的影响因素进行分析讨论,得出学历水平、创业动机、创业风险意识、创业经营模式以及创业培训均对双创收益的提升有促进作用;创业者特征回归分析中R~2值由0.22提升为0.32,ΔR~2的值为0.34,说明自变量对因变量有预测作用;创业者特征对双创收益值为0.329,说明创业者的特征越高,其创业的绩效就越高;创业政策回归分析中R~2值由0.12增加到0.22,ΔR~2的值为0.14,说明自变量对模型有预测能力,且政策越全面有效,对农民的双创收益提升效果越好;创业者社会关系回归分析中R~2值由0.098提升为0.175,ΔR~2由0.175增长为0.433,说明创业者的社会关系越好,农民的双创收益越高。[结论]研究结果说明农业农村双创工作中创业者特征、创业者社会关系以及政策适应可提升创新创业机制的完善,提升双创收益。     

城市化进程中的“资源尾效”和“资源诅咒”——基于中国27个煤炭城市的面板数据分析

传统城市化理论往往强调自然资源对城市发展的正面作用,却对城市化的约束和反向作用问题考虑不够。文章基于"资源尾效"和"资源诅咒"两种假说,利用1997-2012年中国27个典型煤炭城市的数据对其煤炭资源开发与城市化发展的关系进行正负效应检验。结果表明:27个煤炭城市中有16个城市出现"资源尾效",其尾效数值为0.001 755;其余11个城市出现"资源诅咒",其煤炭资源对城市化发展的影响系数为-0.207 2。可见,自然资源的开发强度要处于一个合适的水平,并同时注意资本投入、教育和制度等因素才能最大程度上提高城市化水平。     

Direct Democracy and Local Public Finances under Cooperative Federalism

In this paper, we exploit the introduction of the right of local initiatives in the German state of Bavaria in 1995 in order to study the fiscal effects of direct democracy. Our identification strategy combines difference‐in‐differences and regression discontinuity methods: we compare municipal expenditure and revenue between pre‐ and post‐reform periods at population thresholds where the signatures needed to launch initiatives and minimum quorum requirements decrease discontinuously (difference‐in‐discontinuities design). The results suggest that stronger direct democratic institutions lead to an expansion of local government size.     

On the volatility spillover between lslamic and conventional stock markets: A quantile regression analysis

This paper aims at analyzing the degree and structure of interdependencies in terms of volatility (transmission, contagion) between Islamic and conventional stock markets on calm periods and at times of financial fragility and crisis. We focused on the recent financial instability periods and used the Quantile Regression-based GARCH model. Main results lead to very interesting conclusions. First, it has been found that Islamic stock markets are not totally immune to the global financial crisis. Second, a very strong interdependence is sensed from the conventional to the Islamic stock markets, especially, from the conventional developed markets to the Islamic Emerging and Arab markets and to the Islamic developed markets. Finally, it has been proved that the interdependencies from conventional to Islamic markets are propagated between Islamic markets. Our findings suggest that the Islamic finance industry does not seem able to provide cushion against economic and financial shocks that affect conventional markets.     

Does international capital flow lead to a housing boom? A time-varying evidence from China

This paper examines the causal relationship between the housing prices (HP) and the international capital flows (ICF) in China. With structural changes existing, we find that long-run relationship using full-sample data is unstable, suggesting that traditional Granger causality test is not reliable. However, we further find an unstable short-run relationship between ICF and HP when assessing the stability of the parameters and there are bidirectional causal relationships between ICF and HP for several sub-periods. Additionally, our findings indicate both positive and negative bidirectional causal relations between the series. Based on the arbitrage of ICF, the results suggest that the rise of Chinese HP is the underlying force for the inflows of international capital. Meanwhile, a surge in capital inflows may be accompanied by a rise in the price of housing. This confirms the theoretical analysis that there is an interconnected transmission mechanism between the ICF and the HP, which is diverse and depends both on the flow of ICF and on other factors.
