The impact of urban characteristics on the spread of Covid-19 in 2020: The case of Java Island cities, Indonesia 2020年城市特征对Covid-19传播的影响:以印度尼西亚爪哇岛城市为例

The world has been combating the Covid-19 global pandemic for almost a year, with cities being at the centre of the fight against the pandemic. However, variations in urban characteristics, population, economic size, and connectivity have led to different impacts of the pandemic's dispersion between cities. The pandemic has disrupted social and economic activities in the Java metropolitan area, which accounts for more than 60% of the national economy and boasts a population of more than 60 million people. Using spatial and econometric analysis on the Java metro area as a case study, this paper shows that large cities and core-metropolitan areas are more prone to the pandemic due to higher population density and commuter rate;these factors determine the number of positive cases. This study highlights the importance of spatial and economic activities in urban policies for the containment of the spread of Covid-19.
近一年来,世界一直在与Covid-19全球大流行作斗争,城市处于抗击这一流行病的中心。然而,城市特征、人口、经济规模和连通性的差异导致了大流行在城市之间分散的不同影响。大流行扰乱了爪哇大都市区的社会和经济活动,该地区占全国经济的60%以上,拥有6000多万人口。本文以爪哇都市区为例,通过空间和计量分析发现,大城市和核心都市区由于人口密度和通勤率较高,更容易发生大流行,这些因素决定了阳性病例的数量。本研究强调了空间和经济活动在城市政策中对遏制Covid-19传播的重要性。

Surface curvature analysis of bivariate normal distribution: A Covid-19 data application on Turkey 双变量正态分布的曲面曲率分析:土耳其新冠肺炎数据的应用

Principal curvatures have free-form rigid surfaces' invariant features. Therefore they are widely used in several fields for various applications, such as determining the corresponding points between an object and a free-form scene. In this study, the authors analysed the surface curvature of a bivariate normal distribution. A novel approach for classifying bivariate normal surfaces based on curvature statistics concerning correlation structures is presented. The principal curvatures, Gaussian, and mean curvatures were obtained using the data generated from the bivariate normal distribution. The degree of dependency bivariate data directly affects the shape and curvature structures of the bivariate normal distribution surface. Different parameters, from uncorrelated to highly correlated variables, for the correlation of the bivariate normal distribution based on the data have been examined. The effects of the correlation on the distribution surface characteristics have been analysed individually and collectively. This study presents theoretical results in addition to the results of the simulation and real datasets. The simulation data presents the relationship between the independence of the variables and the uniformity of the kappa(n2) values. The other application is based on the curvature properties of the bivariate normal surface on Covid-19 as real data.
主曲率具有自由形式刚性曲面的不变特征。因此,它们被广泛应用于多个领域的各种应用,例如确定物体与自由形式场景之间的对应点。在这项研究中,作者分析了二元正态分布的表面曲率。提出了一种基于相关结构曲率统计的二元法向曲面分类方法。利用二元正态分布生成的数据得到主曲率、高斯曲率和平均曲率。二元数据的依赖程度直接影响二元正态分布曲面的形状和曲率结构。不同的参数,从不相关到高度相关的变量,对二元正态分布的相关性进行了基于数据的检验。对相关系数对分布面特性的影响分别进行了分析和综合分析。本研究除了给出仿真结果和实际数据集外,还给出了理论结果。仿真数据显示了变量的独立性与kappa(n2)值的均匀性之间的关系。另一个应用是基于Covid-19的二元法向曲面的曲率特性作为实际数据。

Tatabanya has been among the most successful Hungarian towns in attracting foreign direct investment (FDI), which now plays a determining role in its economy. Can already operating, foreign-owned firms, along with the attraction of new firms alleviate the negative economic consequences of the COVID pandemic? What other FDI-related policy options are available for the local government to handle the negative consequences of the crisis? This question is analysed based on publicly available information and interviews taken with representatives of the local government and industrial park. It shows that foreign-owned firms already operating in various industries and coming from numerous countries played a stabilising role during the crisis, especially in the labour market and local tax revenues, mainly because of the large-scale and diverse local FDI. However, this article also shows that local FDI is loosely embedded and shows limited signs of upgrading, thus its positive impact on Hungarian-owned local firms is limited. Further, new FDI projects initiated by nonlocal players due to the increasingly limited manoeuvring room of local authorities are assumed to increase the vulnerability of the town's economy due to their one-sided specialisation and contribution to low levels of embeddedness and upgrading. In addition, they may have negative local environmental and infrastructural impacts. Thus, in handling the negative consequences of the crisis, local authorities cannot rely on attracting new projects, and those attracted by the central agencies have shortcomings from the point of view of handling the negative consequences of the crisis. Therefore, from the point of view of local authorities, a strategy aimed at increasing the embeddedness of FDI already present and fostering their upgrades may be fruitful.
塔塔班尼亚是匈牙利吸引外国直接投资(FDI)最成功的城镇之一,外资现在在其经济中起着决定性作用。已经运营的外资企业以及新企业的吸引力能否缓解新冠疫情带来的负面经济后果?地方政府还有哪些其他与外商直接投资相关的政策选择来应对危机的负面影响?这个问题是根据公开信息和对当地政府和工业园区代表的采访进行分析的。报告显示,在危机期间,已经在各个行业开展业务并来自许多国家的外资企业发挥了稳定作用,特别是在劳动力市场和地方税收方面,这主要是因为大规模和多样化的当地外国直接投资。然而,本文也表明,当地FDI嵌入松散,升级迹象有限,因此其对匈牙利本土企业的积极影响有限。此外,由于地方当局的回旋余地越来越有限,非本地参与者发起的新外国直接投资项目被认为会增加城镇经济的脆弱性,因为它们的片面专业化以及对低水平嵌入和升级的贡献。此外,它们可能对当地环境和基础设施产生负面影响。因此,在处理危机的负面后果时,地方当局不能依靠吸引新项目,而从处理危机负面后果的角度来看,那些由中央机构吸引的项目存在缺陷。因此,从地方当局的角度来看,旨在增加已存在的外国直接投资并促进其升级的战略可能是富有成效的。
