美国行政中心空间与规模特征及其成因研究

行政中心是行政区划的基本要素之一,行政中心尽量靠近地理中心对行政管理和促进区域发展平衡有积极的理论和现实意义。文章提出了行政中心与地理中心偏差的计算公式,运用空间统计分析方法结合Ar-cGIS软件,以美国为例,分析了美国县治与地理中心地理偏差的空间分布和数据特征以及州府与州最大城市的人口规模关系特征,总结了产生以上特征的自然、历史和政治上的原因,并运用空间可视化方法直观地显示分析结果。分析结果表明：①美国的县治普遍比较接近地理中心,其接近程度有由东部向西部递减的趋势且存在一定的空间集聚;②州府大多数并非州最大城市,人口较少。最后从行政中心区位选择和区域发展平衡两方面得出对中国的启示,为中国行政区划改革和区域经济发展提供借鉴。

Asymptotic expansion of S-estimators of location and covariance

By means of a straightforward application of empirical process theory, we show that S-estimators of multivariate location and covariance are asymptotically equivalent to a sum of independent vector and matrix valued random elements respectively. This provides an alternative proof of asymptotic normality of S-estimators and clearly explains the limiting covariance structure. It also leads to a relatively simple proof of asymptotic normality of the length of the shortest α-fraction.

The determinants of the location of foreign direct investment in UK regions†

This article employs a database of over 2000 observations of Foreign Direct Investment (FDI) projects in UK regions. We analyse this data by means of various multinomial and conditional logit models in order to identify the major determinants of the location choices of these inward investments. Having controlled for the various characteristics of inward investing firms, the projects and the regions, our results suggest that existing regional specialization is the single most important determining feature of where inward FDI locates. In addition, London is seen to benefit primarily by the immigration of new investments, the majority of which are related to service sector activities.     

Standardization in electronic money

Abstract

Electronic money services are provided by the combination of Integrated Circuit (IC) cards and terminals. The compatibility of different brands of electronic money can be enabled by firms' joint adoption of standard terminals. In this paper, we analyse the effect of achieving compatibility among different brands of electronic money. We show that, if the unit production cost of a standard terminal is not so much different from that of a non-standard one, firms' joint adoption of standard terminals will increase the total sales of IC cards and the network size of terminals, thus raising consumers' surplus and firms' profits. On the other hand, if the unit cost of a standard terminal is so high that firms are discouraged from voluntarily adopting standard ones, the government may employ subsides to enhance efficiency. However, if the duty of implementing standardization is placed solely on the firms without subsidies, all the agents, including consumers and retailers, will be left worse off.

Towards Trade Equalisation: A Network Perspective on Trade and Income Convergence Across the Twentieth Century

An enduring dynamic of the twentieth century is the dramatic expansion of global trade with increased partners, goods, frequency and volumes. Most trade explanations such as the Heckscher–Ohlin, new trade theory, gravity models, and Ricardo and Sraffa focus on how bilateral import and export volumes and intermediate input goods are driven by decreased financial and information transaction costs. Extending work on trade flows and economic development, we derive several network measures of degree, betweenness and eigenvector centrality from dyadic trade flows from 1960 to 2009. We then empirically explore the interactive effects of trade connectivity, economic production and stages of development on income convergence and trade equalisation. We empirically find clear patterns towards a new phenomenon, both sigma levels and beta rates trade convergence and equalisation for our entire sample. Visualising sigma and beta convergence for seven major trading nations from 1920 to 2010, we believe offers new insights into economic development theory if only beginning to loosen the knot of trade, growth and globalisation.     

The ECFA and its expected effect on cross-strait trade and investment: a Taiwanese perspective

To come to terms with the realization of ASEAN+1, Taiwan had concluded with mainland China a special free trade agreement (FTA), the Economic Cooperation Framework Agreement (ECFA) in June 2010. This framework agreement provides an early harvest agreement of near-term tariff elimination, including detailed product schedules for goods and services from each side, with the final shape of fuller trade liberalization in goods and services taking years to negotiate and realize. The conclusion of the ECFA has been considered as a major breakthrough in cross-strait talks and economic relationships, even though it is by no means free from controversies inside Taiwan. The authors are therefore motivated by hot debates in Taiwan to reflect on the expected trade effect of the ECFA by taking into account the factor of cross-strait global production networks. In particular, we examine with a proposed model and statistical robustness, the trend of Taiwan-based firms' localization in mainland China, driven in part by constant movements in global production networks, which generates complicated and dynamic relationships between Taiwan's investment-induced trade and structural shift in Taiwan's exports to mainland China. Based on our empirical findings, we reflect on the conventional views on the trade effect of the free trade agreement. The results of our analyses tend to support a cautious view about the trade effect of the ECFA. Without denying the significance of the ECFA and deepening cross-strait economic relationships, we argue that the impact of the ECFA should be interpreted in a wider context than just the trade perspective, as the conventional wisdom and the existing evaluations suggested.
