辽宁沿海经济带地脉文化旅游开发利用的经验、问题与对策

地脉文化也被称为地脉和文脉，是一个地方旅游发展的基石。根据地脉文化与旅游产品关系对比可以将旅游开发分为两类四型：（1）旅游产品扎根于地脉文化发展模式 （根基稳固、主次分明）；（2）旅游产品脱离地脉文化发展模式 （左顾右盼、横生枝节）。本文根据这一基本原理对辽宁沿海经济带旅游发展及旅游产品进行了系统分析，总结了辽宁沿海经济带地脉文化旅游开发利用的经验、问题与对策建议。结果显示：辽宁沿海经济带的地脉文化基础有 “海” “滩” “宜” “河” “港” “城” “工” “农” “山” “史”十大方面。 “海” “城” “山”的旅游产品是辽宁沿海经济带各地当前旅游发展主要方向； “滩” “农” “史”旅游产品是辽宁沿海经济带各地当前旅游发展主要方向； “滩”“农”“史”正在发展； “宜”（宜人气候、度假资源）表面发展丰富，实际潜力巨大； “河”（河流、湖泊、水库） “港” （港口） “工”（工业旅游）是被忽视或者发展滞后的地脉文化资源。

Market based price support program: an alternative approach to large scale food procurement and distribution system

In most developing countries of the world, large scale public food procurement and distribution systems (PFDS) have become too expensive for the country governments to support from their own resources. Despite high financial and administrative costs of the programs, the degree of seasonal price stabilization and price support achieved through the activities remain quite low. Using the Bangladesh PFDS as a case study, this research indicates that considerable improvements in price support can be achieved by providing credit to the farmers immediately after the harvest. If the government procurement is reduced by 50 per cent in Bangladesh, and providing 150 per cent of the cost of running PFDS as credit, Bangladesh can improve the farmers' income and achieve better stability of cereal prices at a cost less than one-third of the current costs of the PFDS.
