西三角经济圈的合理性分析——基于空间经济学基本原理

通过运用Walter Christaller提出的中心—地方理论,以及空间经济学的基本原理,建立了一个以重庆、成都、西安三地区为支撑点的空间区域经济模型。通过模型分析西三角经济圈的合理性,并为西三角经济的进一步健康发展提出有利建议。     

STRATEGIC OUTSOURCING UNDER ECONOMIES OF SCALE

We show that economies of scale in upstream production can lead both the disintegrated downstream firm as well as its vertically integrated rival to outsource offshore for intermediate goods, even if offshore production has a moderate cost disadvantage compared to in‐house production of the vertically integrated firm.     

新一轮土地利用总体规划耕地需求量预测研究——以吉林省为例

耕地是土地利用规划调整指标中的重要指标,做好耕地总量的预测工作,对于保护耕地,实现耕地总量动态平衡具有重要意义.耕地需求量预测有数学模型预测法、粮食安全角度预测法、部门预测法和基于社会经济发展战略预测法等几种常用方法,以吉林省为例,运用数学模型和粮食需求预测方法,对全省2010年、2020年耕地需求量做出了初步预测,结果分别为551万公顷和547万公顷.以此作为新一轮土地利用总体规划期的吉林省耕地需求量.

《说文解字》含“皃”字释义语研究

《说文解字》的体例通常包括解释字义和分析字形,其中解释字义的部分称为释义语。通过分析研究,我们发现在《说文解字》中存在着包含＂皃＂字的这一类特殊的释义语。含＂皃＂字释义语在分布的部首方面具有规律性,其语法结构分类具有多样性,同时在与含＂也＂字释义语的比较中,体现出了自身的特殊性。     

It is where you are that matters: the spatial determinants of rural poverty in India

The spatial patterns of poverty in India are of considerable importance in themselves and for development theory and practice. This article examines the determinants of rural poverty in India using spatial econometric methods. It finds that while agricultural growth is the key determinant of rural poverty declines, there is significant spatial dependence in the growth rates of agricultural output. Irrigation is the primary driver of agricultural growth, and spatial variations in irrigation development seem to be associated with agro‐ecological conditions which may be vastly different within Indian states, parts of which may be similar to those prevailing in geographically contiguous states. Poverty reduction strategies need to be designed in the light of spatial factors and using spatial methods.     

Does contact improve attitudes towards migrants in China?

Over the past three decades, China has experienced significant internal migration. However, migrants are often socially segregated and discriminated against in their destination cities in China. This paper uses a large representative survey to investigate whether interpersonal contact between urban locals and migrants improves urban locals’ attitudes towards migrants. The novel part of this paper is to examine the effect of different contact experiences on multiple dimensions of attitudes. The results show distinct patterns between the effects of non‐intimate and intimate contact experiences. All the OLS results, IV results and IV results together with Lewbel's ( 2012 ) heteroscedasticity identification approach suggest that non‐intimate contact experience only significantly improves willingness to engage in non‐intimate interactions, and the magnitude of the effect reduces as the intimacy level of the intended interaction increases. On the contrary, intimate contact experience significantly improves willingness to engage in both non‐intimate and intimate interactions.     

An Examination of the Determinants of In‐Flight Duty‐Free Shopping: Hedonic and Utilitarian Motivations

This research note presents the findings of a study that empirically examined air passengers' in‐flight duty‐free shopping behaviors in the perspectives of utilitarian and hedonic motivations. On the basis of the primary data collected from 212 air passengers in Taiwan, empirical findings revealed that both utilitarian and hedonic motivations affect air passengers' intentions to browse in‐flight duty‐free shopping catalogues. Findings also showed that hedonic motivation does not directly influence air passengers' in‐flight purchase intentions. Instead, a higher utilitarian motivation can directly enhance passengers' in‐flight purchase intentions. Copyright © 2012 John Wiley & Sons, Ltd.
