环城休闲农业景观(ATL-ReBAM)营建 研究——以成都为例

乡村振兴背景下，国家对休闲农业发展提出了更高 层次的要求。针对休闲农业景区分布零散、景观同质化且缺少 呼应、地域性特征弱等现存问题，将旅游学科与风景园林学科 的理论与实践相结合，从环城游憩带的视角出发提出环城休闲 农业景观(ATL-ReBAM)，并构建“三带”景观空间模式。 该模式符合城市居民出游规律和市场需求，与城市周边的资源 分布规律相吻合，有利于地域风土特征的有效传承。以成都为 例，根据其休闲农业景观空间演化特征和已有休闲农业景点分 布特征，尝试构建成都环城休闲农业景观的“三带”空间结 构，并进一步提出具体的景观营建策略。     

河西地区农牧地域分异与农牧耦合探讨

农牧耦合存在两种基本耦合类型:一是特定地域农(牧)生态系统中农牧业生产之间的内部耦合;二是不同地域农(牧)生态系统之间的农牧空间耦合。在对河西地区农牧空间耦合的自然环境、历史发展、现状结构和问题分析基础上,结合对农牧空间耦合的理论探讨,提出了河西地区农牧空间耦合的发展对策。     

产业结构软化及其对世界经济发展的影响

产业结构的状态总是随着经济发展的变化而处于不断变动之中。20世纪中期以来，以信息技术革命为核心的新技术革命的兴起加速了世界产业结构的全方位变革，出现了产业结构软化的趋势。产业结构软化趋势主要表现为产业结构服务化、高技术化、融合化和国际化，它是世界经济发展的必然结果，同时又对世界经济发展产生了重要的影响。     

干旱区绿洲城镇绿色基础设施网络构建 研究——以新疆阿拉尔市为例

随着全球气候变暖、生物多样性减少、生境破碎化等 环境问题日趋严重，“一带一路”沿线国家和地区在生态文明 建设上面临着共同的挑战。如何在有限的资源条件下合理布局 绿色基础设施以满足人类福祉的需求，仍是当前理论研究的热 点和景观管理实践的主要难题。以新疆阿拉尔市为例，基于形 态学空间格局分析、最小路径分析等方法识别对地区景观生态 格局具有重要影响的源地与廊道，通过补充战略点的方式对网 络进行优化，进而结合区域实际状况提出绿色基础设施网络的 构建思路。研究结果可为阿拉尔市及阿克苏地区生态修复和绿 地系统规划提供理论及实证依据，也为“一带一路”其他干旱 区城镇绿色基础设施布局与生态安全格局构建提供可资借鉴的 思路和方法。     

Explaining Real Commercial Rents Using an Error Correction Model with Panel Data

This paper presents rent models for retail and office property in the United Kingdom. Panel data are used covering eleven regions for 29 years, enabling us to overcome the limitations of a relatively short time series. We use an error correction model (ECM) framework to estimate long-run equilibrium relationships and short-term dynamic corrections. The combination of panel data and an ECM is an innovative approach that is still being developed in economics. We construct new supply series that combine infrequent stock data with more frequent construction data. Separate regional models are estimated for retail and office properties. The regions are then combined into a number of panels on the basis of the income and price elasticities in the long-run and short-run models. Unlike previous studies, we find no evidence of a board north–south divide between low growth and high growth regions. Like these studies we do find a London effect: in London, demand elasticities for space with respect to both price (rent) and income are much lower in magnitude. We conclude that, while the economic drivers may vary, there is no evidence of differences in the operation of the regional property markets outside London. Elasticities for retail and office are similar. Our final models are parsimonious with single measures of economic activity and of supply and always support the use of an ECM.     

Aging and Retirement: Evidence Across Countries

How do demographic factors influence retirement? Using a large cross-country data set, I show that in countries with a larger share of elderly in their population the length of retirement is longer. This result holds true if I control for wealth effects, and when the effective labor force participation rate of the elderly is used instead of the official retirement age. Retirement policies and the social security size are strictly related: a new variable, representing the aggregate relevance of retirement policies, turns out to be significant in explaining the size of social security. Finally, the total amount of social security transfers is positively related with the increase of the elderly population, while in per capita terms this relation is not significant.
