Citizen involvement in promoting sustainable mobility

This article proposes a methodology for promoting public involvement in the planning process for the promotion of sustainable mobility. The concept of the focus group (FG) is widened and a method based on holding larger groups defined as mega focus groups (MFG) is proposed. These MFG allow all sections of society to be represented in the participation process, thereby involving the population at a strategic level in subjects of general interest to society and later, holding smaller FGs on more specific subject matters (tactical level).The advantage of the larger MFG over the smaller FG is that they can obtain more information (between 40 and 60 people take part) from easily run meetings (similar to the FG). The MFG also provide a territorial representation of peoples’ opinions and serve as a mechanism for selecting the participants in the smaller focus groups. The information extracted from both the MFG and FG about people’s perceptions of sustainable mobility provides the background to the design of pilot surveys on urban mobility. For a better understanding of the development of this method and its possible applications in any town or city the article includes its practical application in the medium sized city of Santander (Northern Spain).

城市化与潜在增长率:基于长期视角的增长效应评估

从单个国家不同阶段的纵向来观察,城市化与经济增长之间的相关性强弱程度存在显著差异;横向跨国对比来看,不同国家城市化率与经济增长之间的关系也不存在统一的范式,城市化既可能是经济增长的结果,也可能是经济增长的动力。中国未来城市化的速度将不可避免地放缓,人口结构也将逐步跨越老龄化的时间窗口,这会对潜在的经济增长能力产生负面冲击;同时,中国分散型的城市化抑制了创新、规模经济和专业分工带来的增长效应;中国城市化进程表现出了较强的"中心偏向","中心—外围"式的城市化层级结构扩大了区域差距。     

新建还是并购:中国企业成长方式及影响因素研究

企业依赖于新建和并购这两种方式而成长。不同方式各有优劣,选择何种方式将受多种影响因素。本文在回顾企业成长理论并借鉴彭维刚(2007)企业战略资源特质—发展环境的逻辑框架基础上,结合中国企业制度背景,并以中国A股上市公司2006年数据为基础,实证检验了影响中国企业成长方式选择的主要因素。结果表明:(1)中国企业成长普遍存在新建偏好,且国有控制企业表现得更为明显;(2)从发展战略看,与西方理论预期不同,中国企业多元化战略、成长速度等与公司成长方式选择之间并不存在相关性;(3)从资源角度,人力、技术与品牌等资源优势越强的企业,越倾向于采用并购方式;但财务资源与实力与成长方式选择间并不直接关联;(4)从发展环境看,企业在并购或新建方式选择时,应以企业所在区域的市场化程度为依据,以适应或克服市场环境之不足。实证结果表明,企业所在区域的市场化程度越高,越倾向于采用并购成长模式,反之则倾向于新建方式。     

‘Mainline’ telecommunications infrastructure, levels of development and economic growth: Evidence from a panel of developing countries

This paper assesses the growth impact of telecommunications infrastructure investment in developing countries by subjecting country-specific data on mainline tele-density and per capita growth to a Granger causality test within a panel cointegration framework. The results suggest that growth effects vary widely across country groupings reflecting different levels of development. Mainline tele-density and per capita growth strongly reinforce each other for countries that are relatively less developed. The reinforcement effect is even stronger for emerging countries that can be identified by their higher than average growth rates. In contrast, there is, at best, weak evidence of bi-directional causal links between the two variables for countries that are relatively more developed. These differences in the mainline tele-density and per capita growth relationships suggest that investment in telecommunications infrastructure, with its potential to generate high growth return, may serve as the critical tool for driving the growth and development process forward in the less developed countries.     

Protein efficiency per unit energy and per unit greenhouse gas emissions: Potential contribution of diet choices to climate change mitigation

The production, transport and processing of food products have significant environmental impacts, some of them related to climate change. This study examined the energy use and greenhouse gas emissions associated with the production and transport to a port in Sweden (wholesale point) of 84 common food items of animal and vegetable origin. Energy use and greenhouse gas (GHG) emissions for food items produced in different countries and using various means of production were compared. The results confirmed that animal-based foods are associated with higher energy use and GHG emissions than plant-based foods, with the exception of vegetables produced in heated greenhouses. Analyses of the nutritional value of the foods to assess the amount of protein delivered to the wholesale point per unit energy used or GHG emitted (protein delivery efficiency) showed that the efficiency was much higher for plant-based foods than for animal-based. Remarkably, the efficiency of delivering plant-based protein increased as the amount of protein in the food increased, while the efficiency of delivering animal-based protein decreased. These results have implications for policies encouraging diets with lower environmental impacts for a growing world population.

金融中介发展、利率市场化与县域资本配置效率

“先农村、后城市”的利率市场化改革以及县域金融中介体系的发展,共同推进了县域地区的金融深化进程,这对县域经济究竞带来了怎样的影响,是否可以通过优化资本配置效率促进经济增长？本文实证检验了金融中介发展以及利率管制放松对县域地区资本配置效率的影响。研究结果表明,金融中介的规模扩张促进了县域地区资本配置效率的改善;贷款利率上限的放开较为显著地改善了县域地区的资本配置效率,但随着利率市场化改革的推进．这种积极影响已逐步弱化．
