城市加速扩张、政府责任与服务业发展:以北京为例

大城市加速扩张是经济发展到一定阶段的必然产物.北京正在加速向外扩张,但是,除中心城区以外的绝大多数地区在居住、就业、购物休闲等方面难以达成平衡,不足以吸引中心城区的人口和产业,从而进一步加剧了中心城区在交通、住房和公共服务等方面的紧张局面.以上困境正是北京服务业发展的大好机遇,为适应城市快速健康发展的需要,政府必须承担更多的责任,在郊区的交通、基础教育、医疗保健、治安等方面增加投入,更应该鼓励各种产业尤其是劳动密集型的服务业(尤其是商业)在郊区的发展,而不应该人为阻碍其发展.     

Can the North American ski industry attain climate resiliency? A modified Delphi survey on transformations towards sustainable tourism

As global temperatures increase, does accelerating climate change represent an existential crisis or a manageable challenge for the ski industry? Despite considerable evidence demonstrating the global ski industry is in the early stages of a climate-induced transition, global research on ski industry stakeholder perspectives shows varied levels of climate risk awareness, a focus on future vulnerability, and limited engagement in adaptation. Within North America, research has focussed on the physical climatic impacts to ski operations and possible skier responses, yet there lacks insight into industry perceptions on current and future climate vulnerability. This study fills this important knowledge gap using a Delphi survey to engage 52 leaders from across the continent in a dialogue on strategic climate responsiveness. Results demonstrate North American ski industry leaders’ climate risk perceptions range widely, and opinions diverge over if or how to respond at both an industry and destination scale. Simultaneously, industry experts believe mountain tourists increasingly value nature-based activities, place-bound products, and corporate responsibility. Analysing industry leaders’ responses through Enlightened Stakeholder theory highlights how aligning supply-side environmental management with demand-side tourist experiences may create opportunities for new partnerships, innovations, policies, and strategies needed to achieve climate-resilient and sustainable futures.

Tracking urban sprawl: Using spatial data to inform farmland preservation policy

The development of state farmland preservation policies has primarily relied upon results of the Census of Agriculture that is updated every 5 years by the USDA National Agriculture Statistics Service. Questions about the suitability of the Census of Agriculture center on the measures of total farmland and total cropland as reported by agricultural producers. The reliance on these variables fails to distinguish between conversion to developed uses and other fluctuations in the total availability of farmland. This inability to directly measure farmland conversion to developed uses has been shown to influence state level farmland preservation policies. The policies of Illinois and Indiana highlight the disparate approaches, with Illinois pursuing an intensive policy to protect farmland and Indiana choosing to not address farmland preservation at a state level. In order to assess the suitability of the different approaches to farmland preservation policy it is critical to evaluate the Census of Agriculture data used to justify the policies of Illinois and Indiana.

统筹城乡发展是对完善社会主义市场经济体制的有效探索

中国建设社会主义市场经济体制的探索,经历了一条先农村、后城市,然后进行统筹城乡综合改革三大阶段。统筹城乡发展成为探索中国推进制度转型发展,完善社会主义市场经济体制的重大战略。统筹城乡发展对社会主义市场经济体制完善的主要路径是政府主导建立社会主义城乡统一大市场,规范市场运行,弥补市场失灵,同时推进基层民主建设以弥补集权管理制度不足。制度贡献将成为统筹城乡发展对推进国家现代化进程的最大贡献。     

A study on the tourism practitioners＇ perception of tourism impact： a case study of Hainan,China

This study examines the urban population of tourism practitioners perceptions of economic, environmental, and social impacts on cultural, convention, and sport tourism may have in Haikou and Sanya. Hainan, China. The study uses a modified Urban Tourism Impact （UTI） to examine economic, environmental, and social perceived impacts. Analysis of the data includes testing three models of structural relationships between tourism impacts and support for development in each of the tourism market sub-divisions through a confirmatory factor analysis. The results of this study show that the positive economic impacts consistently exert influence on predicting support for tourism development in all three models. However; the social impacts play a greater explanatory role with all three market segment, the negative environmental impacts play a role in determining support for sport tourism only. Differences have been found with those with a higher education level in predicting support for cultural tourism, but not convention or sport tourism.
