基于最优插值函数优选的小城镇商业用地地价空间结构分析——以西安市蓝田县城区为例

根据在西安市蓝田县城区调查的商业用地地价资料,利用ArcGis软件,从8种常用的插值方法中,以估计值与观察值的标准差最小为原则,筛选出适合于商业用地建立GRID数据的最优插值函数为克里金指数半变差函数模型,并利用该模型建立了商业用地的地价面,在此基础上对商业用地的地价空间结构进行了分析。结果表明:小城镇商业用地地价的变化呈同心圆结构,即城市中心区地价最高,向外逐渐降低。商业用地地价与道路两侧的商店密度性、临街道路的类型以及文化娱乐设施的分布密度正相关,相关系数分别为0.946、0.693和0.659;而与金融保险机构的个数以及土地所有权的性质相关性不强。     

Are we spending too much to grow? The case of Structural Funds

We evaluate whether the impact of EU Structural and Cohesion Funds (EUF) on Member States’ regional economic growth depends on the intensity of treatment, measured by the normalized amount of funds distributed in each region. We use an original data set that covers all the main sources of EUF and extend the regression discontinuity design to the case of continuous treatment. The results suggest an average positive effect on regional growth. The estimated conditional intensity‐growth function is concave and presents a maximum value. Therefore, the exceeding funds could have been allocated to other lagging regions without reducing the effect on growth.     

GPS-based measurement of geographic spillovers in tourism – example of Polish districts

The agglomeration phenomenon in tourism often spreads beyond the borders of territorial units what is referred to as geographic spillovers. However, the measurement of spatial concentration of tourism demand and economic activity is usually based on statistics collected within regional administrative boundaries and omits the spatial interdependency between neighboring regions. Recognition of such spatial interdependency in the standard procedure to define neighborhood relies on the distance between geometric means (centroids) of territorial units which, however, rarely reflects real ‘centers’ of tourism agglomerations and leads to errors and biased results. Hence, we propose to modify the measures of the neighborhood with the use of GPS coordinates of tourism firms and attractions in order to designate their regional central tendencies and thus to correct (shift in space) localization of centroids of territorial units. We test the usefulness of the new approach to obtain a more precise measurement of spatial concentration when tourism spills over beyond the boundaries of territorial units using the example of Polish districts. We employ the exploratory spatial data analysis (spatial statistics) and spatial regression models – to assess the difference between using traditional centroids and GPS coordinates in defining neighborhood and determining spillover effects in regional analysis. Furthermore we apply the new method into the model of tourism potential in order to identify spillover effects in Polish regions. We use the data collected by Central Statistical Office (tourists staying overnight in 379 districts in 2014) and by Polish Tourist Organization (14,390 GPS coordinates of individual entities: tourism firms and attractions). The neighborhood determined with the use of GPS coordinates to measure the distance between centers of tourism agglomerations eliminates the dependence of the results on the administrative boundaries – but only to some degree. The challenge is to identify tourism agglomeration phenomenon as such, based on the mobility of tourists in space.     

Determinants of regional resilience to economic crisis: a European perspective

The impact of the economic crisis has been highly asymmetric across the European regions. The objective of this paper is to investigate the determinants of resilience to economic crisis across European regions. Regional economic resilience was assessed based on employment changes during 2008–2013, while socioeconomic determinants were analysed pre-crisis (2002–2007). A highly heterogeneous pattern of resilience was observed within countries, while significant differences were also revealed between the continental northern-central regions and the southern periphery. A multilevel logistic regression model indicated the magnitude of country-effects on the performance of regional employment during crisis periods. Both EU-referenced and country-referenced regional resilience identified the positive effect of accessibility and the negative effect of a large manufacturing sector in the ability of regions to withstand recessionary shocks. Education and economic development level positively affected the resilience of both large and small regional European economies. Investing in education enhances the spatial homogeneity across Europe in terms of its ability to react to economic shocks. The results reveal the importance of narrowing disparities among regions and formulating targeted and differentiated regional development policies at country level, taking into consideration the size of the economy of the regions.     

Electoral rule and public sector efficiency: Some evidence from Italian municipalities

We study the effect of Law 81/1993, which introduced a different rule for the election of mayors, on the technical efficiency of Italian cities over the period 1998–2006. Since 1993, municipalities below 15,000 inhabitants vote with a single-ballot system, whereas cities above 15,000 inhabitants are subject to a double ballot. We first estimate the output-oriented technical efficiency of municipalities through data envelopment analysis, and then we perform a regression discontinuity design analysis by exploiting the exogenous change in the electoral scheme at the 15,000 inhabitants cut-off. We find evidence that municipalities voting under a double-ballot rule show lower levels of efficiency—in terms of provision of public goods—compared with cities voting under a single-ballot scheme, by about 6.5%. This effect is driven by inefficiencies registered in specific sectors, that is, police, education, and maintenance of roads. Furthermore, the overall lower efficiency of municipalities voting under runoff is related to the different level of educational attainment of elected mayors, whereas it is not driven by the features of Law 81/1993 relating to the number of lists forming a coalition in support of mayoral candidates and to disjoint votes.

基于健康视角的城市就业者通勤模式选择及影响因素研究——以南京市为例

中国城市出现的居住和就业"空间不匹配"现象，对就业者日常通勤时间和方式产生了重要影响，进而影响就业者健康状况。依托南京市居民身体活动和健康状况问卷调查数据，根据不同通勤方式身体活动量的大小将就业者的通勤模式分为积极通勤、公共交通通勤和机动车通勤三种，构建多项Logistic回归模型探究城市就业者通勤模式的选择及相关影响因素。结果表明：①就业者对自身健康的主观认知和客观身体健康状况以及是否散步等健康行为显著影响通勤模式的选择；②通勤时间、加班等与工作相关的变量与就业者机动车通勤显著正相关，雨雪天气与积极通勤显著负相关；③个体社会经济属性中性别、年龄、家庭人口规模以及是否拥有小汽车等显著影响通勤模式选择。基于研究结果，本文对如何引导就业者选择更加积极和可持续的通勤模式提出了政策建议。     

Integrating pattern and context in spatial archaeology

Traditional approaches to intrasite spatial analysis in archaeology have concentrated on identifying associations among classes of artifacts over a site surface. This focus has tended to ignore the possible effects of contextual constraints on inter-class relationships, for example the “gravity effects” of hearth features on object deposition. Consequently, sets of co-occurring artifact classes defined in space are usually ascribed behavioural significance as “tool kits”, even though they may represent unrelated objects simply discarded into the same spatial location. This paper attempts to illustrate this problem through contextual integration of artifact and feature distributions. Quantitative methods are employed to carry out contextual spatial analysis of artifact distributions from the Upper Palaeolithic rockshelter site Le Flageolet I (Dordogne, France). Results indicate that associations among artifact classes in space might be constrained by feature locations at Le Flageolet I and that contextual interpretations are warranted for the observed inter-class relations.
