为科学、准确研究陕西入境旅游发展的区域差异,文章借鉴研究区域经济规模和位序差异的成熟方法,选取2001--2010年国家和陕西省统计年鉴中陕西省7个重点城市的相关数据(2003年由于非典原因除外),对陕西入境旅游的区域差异进行了研究。发现陕西入境旅游业发展空间差异较大,但有逐渐缩小的趋势,7个重点城市入境旅游发展不平衡且不平衡格局相对稳定等问题。在此基础上,分析了影响陕西入境旅游规模位序差异化的原因。  相似文献

This study assesses the impact of parental involvement laws on adolescent abortion rates and pregnancy rates. The analysis estimates abortion rate and pregnancy rate models using state-level data pooled over time for adolescents aged 15–17 compared to older teens aged 18–19 and adults aged 20–44. The results indicate that parental involvement laws reduce adolescent abortion rates and may, to a lessor degree, reduce adolescent pregnancy rates. Thus, the findings imply that enforcement of parental involvement laws will increase adolescent fertility rates.  相似文献

伴随国际资本流动性的不断增强,越来越多的国家倾向于使用税收激励政策以吸引外国直接投资(FDI),但实践效果却差别很大.针对税收激励政策的有效性问题,国外学术界做了大量研究.早期的研究借助调查和计量经济手段,对税收激励政策在吸引FDI中的重要性进行了考察.随后,学者们进一步探讨了具体税收政策工具对FDI区位决策的影响,并对跨国公司的税收行为做了深入分析.目前,更多的学者开始关注母国税收政策对FDI区位决策的影响,以及税收竞争与协调、税收激励的成本等问题.  相似文献

This paper tests the impact of guanxi on behaviors among firms in a Chinese marketing channel. Guanxi is operationalized in this paper as emotional closeness and interactive state. We find that the emotional closeness between channel-boundary personnel of firms has a positive impact on their exercise of noncoercive power, a negative impact on their exercise of coercive power, and a negative impact on the perceived conflict between them. In addition, emotional closeness has an indirect but positive impact on perceived cooperation. Interactive state between the boundary personnel of two firms has a positive impact on a firm exercising noncoercive power and a negative impact on perceived conflict between them. At the same time, it is positively related to a firm exercising coercive power. This shows not only the significant influence of guanxi on a firm's channel behaviors but also the constructive effects of both emotional closeness and interactive state on marketing channel behaviors in China.  相似文献

This article examines real estate's role in institutional mixed‐asset portfolios using both private‐ and public‐real estate indices, as a means of examining varying real estate‐related risk/return opportunities. In so doing, this article also examines the effects of: (1) increasing the investment horizon, (2) placing constraints on the maximum allocation to any one asset class, and (3) varying the risk preferences of investors. The empirical results suggest—using infinite‐horizon returns and all of the caveats that accompany such a perspective—that real estate allocations of approximately 10–15% of the mixed‐asset portfolio represent an upper bound for most investors. For those investors preferring low‐risk portfolios, (unlevered) private real estate is the vehicle serving this allocation preference; for those investors preferring high‐risk portfolios, public real estate (with its embedded leverage of 40–50%) is the vehicle serving this allocation preference—with such vehicles serving as substitutes for a variety of noncore real estate strategies. In some sense, the distinction between private and public real estate is more about the use of leverage. For those investors preferring moderate‐risk portfolios, an intermediate‐leverage approach seems optimal.  相似文献

We use a factor model and elastic net shrinkage to model a high-dimensional network of European credit default swap (CDS) spreads. Our empirical approach allows us to assess the joint transmission of bank and sovereign risk to the nonfinancial corporate sector. Our findings identify a sectoral clustering in the CDS network, where financial institutions are in the center and nonfinancial entities as well as sovereigns are grouped around the financial center. The network has a geographical component reflected in different patterns of real-sector risk transmission across countries. Our framework also provides dynamic estimates of risk transmission, a useful tool for systemic risk monitoring.  相似文献

Using data from Charlotte, NC, a New South city without a legacy of heavily contaminated properties, we find the distance from unremediated brownfields—typically former industrial properties believed to have modest contamination—to have no effect on residential sales values, but proposed cleanup and actual remediation have positive, substantial, and significant effects especially within 0.5 miles of the brownfield. Our results are consistent whether we examine all property values within a given distance, such as 0.5 miles, or examine discrete distances, such as 0.3–0.5 miles. An estimate of the benefits is on the order of $4 million. (JEL Q51, Q24, Q28, R52)  相似文献
