地域功能视角下旅游引导山地城乡一体化发展策略研究——以河南鲁山县为例

旅游业已经成为中国城乡发展的新动力,在城乡地域功能演化中起到的作用越来越显著。山地丘陵地区在旅游业驱动下,多种地域功能交互重叠,构成了多类型复杂耦合空间,面临着区域可持续发展的模式抉择。本研究以河南鲁山县为例,探讨山地丘陵地区在旅游引导下的城乡一体化发展策略。研究发现：（1）山地丘陵地区的地域功能正在从传统单一的“居住-农业非农业生产”向综合功能的“生态保障-居住-农业非农业生产-休闲文化服务”转变,多类型空间交互特征明显。（2）鲁山县由农业经济主导向旅游经济主导转变,可划分为旅游服务承接平台区、山地生态旅游发展区、特色林业旅游融合区、平原高效农旅融合区,进行中心城区-中心镇-一般镇-中心村的层级划分和产业方向优化。（3）发展策略应强调分层实施、分类引导,优化城乡利用空间,做好城乡地域分类引导,实现资源要素合理配置。研究成果为认识山地丘陵地区地域功能演化规律、制定城乡一体化发展策略提供了科学案例。     

An assessment of value creation in mobile service delivery and the moderating role of time consciousness

This study focuses on the perceived utilitarian value of a new service delivery mode, the mobile channel. The authors develop a framework that incorporates three mode-specific benefits - time convenience, user control, and service compatibility - as well as two costs - perceived risk and cognitive effort - as antecedents of perceived value. Because of the pervasiveness of time criticality as a value-added characteristic of the mobile channel, they also investigate the moderating influence of consumers’ time consciousness. They empirically investigate the model using mobile brokerage services as an illustrative application. The results reveal that the identified antecedents, with the exception of service compatibility, have a strong impact on mobile channel value perceptions, which in turn influence behavioral intentions. The authors also find that time consciousness moderates the aforementioned relationships.     

Volatility, Efficiency, and Trading: Further Evidence

Along the lines of Amihud and Mendelson (1987a, 1989,1991), this study investigates the unique trading mechanism of the Korea Stock Exchange (KSE) and its intraday behavior of stock price volatility. The evidence from this study indicates that the introduction of an additional clearing procedure at the afternoon closing makes price discovery process more efficient than before from the viewpoint of stock price volatility. Hence, such trading mechanisms can be applied to emerging stock markets as well as developed stock markets. In addition, based on intraday analysis, stock price volatilities appear to occur mainly during the trading period, not during the lunch break or overnight period. Consequently, the results confirm the previous studies that information arrival and trading activities are the main sources of volatility.     

An Exploratory Study of Brand Success: Evidence From the Food Industry

The goal of this research is to identify drivers that influence the brand success, in order to develop a more effective business strategy. An abductive theory approach is adopted and food managers from Italy and Sweden were questioned. The authors modeled the eight correlated first-order factors, using seven independent variables and the dependent variable brand success. The variance-based structural equation modeling approach (partial least square [PLS] algorithm) have been applied. This study provides insight and empirical evidence on brand success. The findings can be employed as more effective brand strategies in a sector that has been under-investigated in academic literature and practice.     

辣木树不同部位γ-氨基丁酸的HPLC分析

用高效液相色谱法检测了辣木树不同部位γ-氨基丁酸的含量,结果表明:每100 g样品中,辣木果实、叶、果皮、花、根、籽及茎中的GABA含量分别为378.39、275.64、194.15、96.42、69.14、27.32 mg与0.00 mg。由此可见,辣木树中富含GABA,且幼嫩部位含量较高,本研究可为辣木产品的质量评价、开发利用以及辣木树中GABA的合成部位与运输情况研究提供理论参考。     

Do Neighbours Influence Value‐Added‐Tax Introduction? A Spatial Duration Analysis

The spatial survival models typically impose frailties, which characterize unobserved heterogeneity, to be spatially correlated. However, the spatial effect may not only exist in the unobserved errors, but it can also be present in the baseline hazards and the dependent variables. A new spatial survival model with these three possible spatial correlation structures is explored and used to investigate the implementation of value‐added tax (VAT) in 99 countries over the period 1970–2009. Estimation is performed by a Bayesian approach through the Markov chain Monte Carlo method. The estimation results suggest the presence of a significant spatial correlation among the VAT introductions of neighbouring countries.     

Weighted Pricing Functionals With Applications to Insurance

Abstract

We explore the role of weighted distributions in pricing insurance risks. In particular, we relate the distributions to actuarial and economic premium calculation principles and in this way provide a unifying methodology for constructing new principles and analyzing known ones.     

Audit Partner Disciplinary Actions and Financial Restatements

This study investigates the signalling role and rectification effectiveness of an audit partner disciplinary system. The signalling role refers to whether sanctions reflect the poor audit quality of disciplined audit partners, and rectification effectiveness addresses whether disciplinary actions enhance subsequent audit quality. The sample consists of Taiwanese listed companies, in the period 2000 to 2006, where the identities of audit partners who sign audit reports and who are sanctioned are accessible. Empirical results indicate that in the pre‐sanction period, the probability of financial restatements by clients of disciplined audit partners is significantly higher than that of non‐disciplined audit partners. The more severe or frequent the sanctions, the higher the likelihood of financial restatements in the pre‐sanction period. These findings imply that audit partner disciplinary actions can serve as a signal of lower audit quality provided by those partners. The rectification effectiveness of disciplinary actions is examined from two perspectives: (1) the effects on subsequent improvements of audit quality of disciplined audit partners; and (2) audit quality enhancement of successor non‐disciplined audit partners who accept clients from disciplined audit partners. Empirical results show a lower probability of restating financial statements audited by disciplined audit partners after sanctions. We also find a lower likelihood of restating financial statements audited by successor non‐disciplined audit partners in the post‐sanction period. Both findings support our conclusion that audit partner sanctions improve audit quality. Overall, audit partner disciplinary actions can signal lower quality audit partners and are effective in enhancing audit quality.     

Convergence in West German Regional Unemployment Rates

Abstract. Differences in regional unemployment rates are often used to describe regional economic inequality. This paper asks whether changes in regional unemployment differences in West Germany are persistent over time. Understanding the persistency of regional unemployment differences helps us to assess how effective regional policy can be. While univariate tests suggest that changes in regional unemployment differences are persistent in West Germany, more powerful panel tests lend some support to the hypothesis that regional unemployment rates converge. However, these tests reveal a moderate speed of convergence at best. Because there is a structural break following the second oil crisis, we also use tests that allow for such a break. This provides evidence for both convergence and quick adjustment to an equilibrium distribution of regional unemployment rates that is, however, subject to a structural break.     

ECB monetary policy and commodity prices

We assess the impact of ECB monetary policy on global aggregate and sectoral commodity prices over 2001–2019. We employ an SVAR model and separately assess periods before and after the global financial crisis. Our key results indicate that contractionary monetary policy shocks have positive effects on commodity prices during both conventional and unconventional monetary policy periods, indicating the effectiveness of unconventional monetary policy tools. The largest impact is documented on energy (fuel) and food commodities. Our results also suggest that the effect of ECB monetary policy on commodity prices transmits through the exchange rate channel, which influences European market demand.
