随着旅游业的兴起,我国风景名胜区的发展进入“黄金时代”。然而在风景名胜区迅猛发展的同时,景区与原居民和谐问题日趋突出,严重影响了风景名胜区的可持续发展。采用理论研究和实践总结相结合的方法,介绍了研究背景,分析了风景名胜区原居民产生的问题,提炼了风景名胜区与原居民协调发展的战略思想,即分类调控、整合管理、分区规划、加大公共投入,在此基础上从安居、乐业、兴产、和谐、保障等方面提出风景名胜区与原居民协调发展的政策建议。 相似文献

The paper examines a quantity–location duopoly game in a spatial discrimination model in which the delivered goods are assumed to be imperfect substitutes or complements. By extending the range of the unit transportation cost analysed in the existing literature, it is shown that a dispersed equilibrium arises in which the choice of the optimal locations is affected by the degree of product substitutability. The interaction between the latter and the size of the transportation cost is also discussed in order to verify its welfare implications. In particular, it is shown that in this spatial framework imperfect substitutability may increase welfare. 相似文献

This study assesses the potential impact of rising world food prices on the welfare of Ugandan households. While Uganda experienced sharply higher food prices in 2008, as a landlocked, food‐exporting country the causes of those price changes were mainly regional and indirect rather than directly transmitted from global markets. Using trade volumes, food prices, and household survey data we describe how Uganda, unlike some other countries, is partially shielded from direct impacts of global food price movements. Although the majority of Ugandans are net food buyers, the adverse impact at household‐level of rising global prices is moderated by the relatively large quantity and range of staples consumed that come from home production. Moreover, several of these are not widely traded. Some population groups in Uganda are vulnerable to rising food prices, however, primarily those for whom maize is an important staple, including those dependent upon humanitarian relief and the urban poor. Only a relatively small group of Ugandan households will benefit directly and immediately from rising food prices—the significant net sellers of food crops constituting between 12% and 27% of the population. In this assessment we do not estimate the level and extent of wider second round effects from these higher prices. 相似文献

This paper assesses governmental performance in its investment, provision and regulation of urban transportation. Attention is given to public bus and rail transit and road transportation. Evidence based on urban transport in US cities reveals substantial allocative and technical inefficiencies that have led to large public transit deficits and severe highway congestion. I argue that it is futile to expect public officials to remedy the situation by pursuing more efficient policies such as congestion pricing and weighing costs and benefits when deciding transit service. The problem is that urban transportation policy is largely shaped by entrenched political forces that inhibit constructive change. The only realistic way to improve the system is to shield it from those influences and expose it to market forces by privatising it. This position is supported by empirical evidence based on simulations for the US and the UK's early experience with privatisation. 相似文献

In this paper, we study the dynamics between house prices and selected macroeconomic fundamentals in Greece. The empirical analysis applies the asymmetric ARDL cointegration methodology proposed by Shin, Yu and Greenwood-Nimmo (2011) over the period from January 1999 to May 2011. The evidence suggests that ignoring the intrinsic nonlinearities may lead to misleading inference. In particular, the results reveal significant differences in the response of house prices to positive or negative changes of the explanatory variables in both the long- and short-run time horizons. The obtained evidence of asymmetry could be of major importance for more efficient policymaking and forecasting in the Greek house market. 相似文献

This paper examines the role of nonfundamentals‐based sentiment in house price dynamics, including the well‐documented volatility and persistence of house prices during booms and busts. To measure and isolate sentiment's effect, we employ survey‐based indicators that proxy for the sentiment of three major agents in housing markets: home buyers (demand side), home builders (supply side), and lenders (credit suppliers). After orthogonalizing each sentiment measure against a broad set of fundamental variables, we find strong and consistent evidence that the changing sentiment of all three sets of market participants predicts house price appreciation in subsequent quarters, above and beyond the impact of changes in lagged price changes, fundamentals, and market liquidity. More specifically, a one‐standard‐deviation shock to market sentiment is associated with a 32–57 basis point increase in real house price appreciation over the next two quarters. These price effects are large relative to the average real price appreciation of 71 basis points per quarter observed over the full sample period. Moreover, housing market sentiment and its effect on real house prices is highly persistent. The results also reveal that the dynamic relation between sentiment and house prices can create feedback effects that contribute to the persistence typically observed in house price movements during boom and bust cycles. 相似文献
