Encouraging enterprise in deprived places is an important objective of the UK government policy. Evidence on the perceptions of entrepreneurs suggests that access to finance may be harder for firms in deprived areas, who may have fewer contacts, less collateral or worse access to mainstream banks. Yet there is little empirical evidence on whether this is actually the case. This paper investigates whether firms in deprived areas are more likely to find it hard to access finance than other firms, using a sample of around 3500 UK small and medium sized enterprises (SMEs). We find that firms in deprived areas are more likely to perceive access to finance is a problem. However, controlling for SME characteristics, firm growth, credit scores and selection effects, we find no evidence that they actually do find it harder to obtain. The results suggest that geographical disparities in access to finance are unimportant for the average firm.  相似文献

Based on the significant amount of literature on the concept of spatial, ecological, and social embeddedness in the Alternative Food Networks (AFNs) research, this study describes the main dynamics related to the involvement of non-conventional farmers in their collective ideas and actions.With a comparison between two European regions: Sardinia and the Community of Madrid, the paper identifies different styles of behaviour among organic producers, whether or not supervised by a control body, and highlights the differences and similarities regarding their ideas about how alternative agriculture has an impact on the environment as well as society. Eco-economies and ecopreneurship are also considered. The aim is to see if, and to what extent, these ideas have a collective character, going beyond the limits of the single farm to reach a regional scale and, thus, if there is a basis for the development of future food-related planning policies. Through the information provided by semi-structured interviews, farmers have been divided into categories according to their degree of embeddedness, described through the main themes that emerged during the interviews. Every farmer has been included in only one category according to his or her main preference, which does not imply the ab-sence of a positive attitude towards other categories.The study aims to contribute to the understanding of how AFN values and methods can boost the improvement of biodiversity and landscape conservation through collective actions which have the power to boost and develop rural initiative at a regional scale.  相似文献

在城市进入大规模的拆迁与重整的今天,人类对“家园”的认知尤为重要。“什么环境空间组合才是我们需要的家园,什么样的空间形式才是适合我们居住的呢?”无疑,这是个值得深思和探究的课题。从传统造园的三个基本形式来展开分析解读,并试图找出一条属于全人类的、未来的、生态的、和谐的城市“家园”的发展之路。  相似文献

Researchers of related topics agree that the large-scale top-down development of a creative cluster by a real estate developer may obstruct rather than facilitate creativity and creative entrepreneurialism. OCT Loft, a design industry park in Shenzhen, China, is being celebrated as an exception. Based on analyses of primary and secondary data, we find that the Loft’s success can be attributed to two factors. First, the choice of design as the target industry was appropriate. Design is a fast-growing industry and thus needs space for expansion. Second, the developer chose tenants with good reputations in the industry rather than those offering the highest rent. Both these factors are difficult to implement. First, a growing industry is hard to find in a city where urban regeneration is needed. Second, the majority of developers cannot pass up maximising rent for a good reputation as OCT did. Indeed, OCT was able to pursue the Loft’s creative success because giving a good impression to potential clients was expected to result in future opportunities that would raise profit further. In sum, a large-scale top-down development can facilitate creative entrepreneurialism but only when the developer is not hasty in demanding an immediate return on investment.  相似文献

This paper studies the performance of auction design features regarding pricing mechanisms and bid selection criteria for securing wildlife zones across different holdings. We compare two pricing mechanisms: a discriminatory‐price auction and a uniform‐price ascending auction, and four bid selection criteria on the basis of: total bid, bid‐per‐value ratio, bid‐per‐area ratio and a mixed criterion where bids are formed on the basis of cost but they are selected based on the bid‐per‐value ratio. We develop a best‐response group‐bidding model for a discriminatory‐price auction where bidders form optimal group bids for individual wildlife zones. In the uniform‐price ascending auction, individual landholders respond to prices, which are successively raised by the auctioneer and whenever all the landholders from a single zone agree to participate (i.e. the first zone is formed), the auction stops. Based on numerical simulations using a bio‐economic model of malleefowl conservation, we observe that the discriminatory‐price auction is more cost‐effective than the uniform‐price ascending auction. However, the budgetary cost‐effectiveness of a discriminatory‐price auction is sensitive to bidder uncertainty about the number of competing bidder groups and the highest cost of establishing a wildlife zone among these groups. In terms of bid selection, the mixed bid selection criterion performs best. We discuss the policy implications of these findings.  相似文献

社区公园是老年人户外活动的主要场所。研究社区 公园空间与老年人户外活动行为的关系,对于满足老年人活 动需求、应对人口老龄化问题具有重要意义。以南京市郑和 公园为研究对象,在实地测绘的基础上,定义公园空间的类 型,并分析各类空间的构成特征。选取公园中5个样本空间进 行观测,从时间和空间2个维度分析老年人公园活动的行为特 征。针对占公园活动人数绝大多数的8种活动,运用数据分析 和ArcGIS技术对行为与空间的关联性进行分析,结合访谈和 Nvivo质性分析发现,空间的尺度、围合性与开敞性、是否受 干扰、景观质量、庇护性是老年人活动空间选择的主要动因; 座椅、遮阴要素、大面积铺装、照明设施、置物设施等则是老 年人需要的空间要素。  相似文献

教育功能作为城市公园功能组成的重要部分,随着 人们日益增长的文化需求,城市公园环境教育的地位日益凸 显。为探究城市公园环境教育评估、游客参与以及解说满意度 之间的关系及作用机制,构建了三者之间的路径模型,以福州 市晋安公园为例,在对294位游客问卷调查的基础上,进行结 构方程验证。结果表明:1)修正后的模型中,建立关系指标 与游客参与相关性最强,有形性对解说满意度的影响最大,认 知层面最能反映环境教育评估;2)游客参与对解说满意度具 有显著正向影响,解说满意度对环境教育评估存在显著正向影 响,游客参与对环境教育评估有显著正向影响;未来公园在进 行环境教育功能提升时,应当将游客参与度以及解说系统满意 度纳入考量。  相似文献
