THE CORPORATE INTERVIEW AS A RESEARCH METHOD IN ECONOMIC GEOGRAPHY*

The open-ended corporate interview as a qualitative research method is proposed as a valuable component of an evidentiary strategy in economic geography. It is argued to be more sensitive than other survey methods to historical, institutional, and strategic complexity. The corporate interview method is particularly appropriate in periods of economic and social change that challenge traditional analytical categories and theoretical principles. Some problems inherent to the method, and strategies for minimizing their impact on the research project, are described.     

Effect of sampling and linkage on fault length and length–displacement relationship

The power-law exponent (n) in the equation: D=cL ⁿ , with D = maximum displacement and L = fault length, would be affected by deviations of fault trace length. (1) Assuming n=1, numerical simulations on the effect of sampling and linkage on fault length and length–displacement relationship are done in this paper. The results show that: (a) uniform relative deviations, which means all faults within a dataset have the same relative deviation, do not affect the value of n; (b) deviations of the fault length due to unresolved fault tip decrease the values of n and the deviations of n increase with the increasing length deviations; (c) fault linkage and observed dimensions either increase or decrease the value of n depending on the distribution of deviations within a dataset; (d) mixed deviations of the fault lengths are either negative or positive and cause the values of n to either decrease or increase; (e) a dataset combined from two or more datasets with different values of c and orders of magnitude also cause the values of n to deviate. (2) Data including 19 datasets and spanning more than eight orders of fault length magnitudes (10⁻²–10⁵ m) collected from the published literature indicate that the values of n range from 0.55 to 1.5, the average value being 1.0813, and the peak value of n _d (double regression) is 1.0–1.1. Based on above results from the simulations and published data, we propose that the relationship between the maximum displacement and fault length in a single tectonic environment with uniform mechanical properties is linear, and the value of n deviated from 1 is mainly caused by the sampling and linkage effects.

Entropy Analysis of Multiple Scale Causality and Qualitative Causal Shifts in Spatial Systems*

Spatial systems are typically characterized by multiple controlling factors and processes operating at different spatial and temporal scales (multiple scale causality [MSC]). An entropy decomposition‐based approach to MSC is presented here in two contexts. First, given maps or distributions of an observed phenomenon at two or more scales, the contribution at more local or global (relative to the primary scale of observation) controls to the observed entropy can be estimated. Second, a theoretical treatment of the entropy decomposition equations shows that as the range of scale is increased by broadening or narrowing resolutions or by incorporating more controls, the influence of larger or smaller‐scale influences not only changes, but may change qualitatively, e.g., in terms of having positive (entropy‐increasing) or negative (information‐increasing) effects. Such qualitative causal shifts have implications for efforts to use any single causal explanation across the molecular to planetary spatial and instantaneous to geological range of scales relevant to physical geography. The entropy decomposition method is illustrated with an application to soil landscapes in the Ouachita Mountains, Arkansas.     

广州市北京路步行街旅游形象策划

商业步行街是当今城市旅游购物和休闲的一个重要场所。广州市北京路是广州历史和现代有名的商业街之一,也是广州的一个著名景点。为了更好地包装广州市北京路的旅游形象,在详细分析其旅游文脉和旅游发展现状的基础上,采用企业识别系统的相关理论,对该区旅游形象MI、BI、VI三个方面进行了较为科学的策划。认为广州市北京路应突出“岭南第一街”的特点,对步行街的企业行为系统、市民行为系统等进行有效管理和规范,并改善现有的视觉景观和视觉标志,着力塑造一个集旅游观光、购物消费和休闲娱乐于一体的旅游形象。

产业地理集聚与外商直接投资产业分布——以北京市制造业为例

外商直接投资理论强调跨国公司的垄断优势和东道国的区位优势决定外商直接投资的产业分布。本文认为外商直接投资的产业分布还可能取决于因产业地理集聚和地方化贸易所形成的竞争优势。本文采用1999~2004年北京外商直接投资的产业流资料建立面板数据回归模型,引入产业地理集聚系数、产业联系等变量来研究影响外资产业分布的因素。统计分析表明,在空间上比较集聚、产业内联系较强的产业能够吸引更多的外商直接投资;前期外商投资对于跟进投资具有显著的示范效应、信息溢出效应以及产业联系效应,从而直接导致外资的产业累积效应。外商也强烈偏好资本技术密集型产业以及在国际市场上具有显著比较优势、盈利率高的产业。外商在充分利用其垄断优势、产业比较优势和竞争优势的同时,也尽量避开实际劳动成本较高和进入壁垒较高的垄断性产业。本文的结果显示,发挥本地优势,完善产业配套,促成产业集群是提升城市吸引外商直接投资的有效途径。     

城市群创新联系网络结构与创新效率研究

引入修正引力模型、社会网络分析方法、DEA模型以及Tobit模型,探讨2001—2015年京津冀、长三角、珠三角三大城市群的创新联系网络结构对创新效率的影响。研究表明：① 创新联系格局方面,京津冀城市群呈现以“京津”为核心的放射状发展特征,长三角城市群呈现以“Z”字形为主轴的类钻石型空间格局,珠三角城市群形成了以珠江口两侧城市为核心、其他城市为重要节点的空间格局;② 在创新联系网络结构特征方面,京津冀城市群呈极核式发展,群内创新联系高度依赖于核心城市,长三角和珠三角城市群由单中心驱动转变为多中心驱动,呈均衡发展特征,京津冀和珠三角城市群创新联系网络具有“小世界”网络特征;③ Tobit模型回归结果显示,三大城市群中,城市节点在城市群创新联系网络中的中心位置、中介地位、对结构洞的运用能力和集聚程度对其创新效率的影响存在差异。     

陆海社会经济关系及其演进研究综述

陆域与海域的社会经济发展是沿海区域可持续发展的重要表现,共同作用于沿海区域经济,但在长期“重陆轻海”的理念下,陆域与海域社会经济关系并未得到有序发展,两者需在长期发展中寻求社会经济关系的平衡点,促进沿海区域绿色协调发展。从海洋经济与沿海陆域经济发展、陆海联动、陆海一体化、陆海统筹等4个方面综述了陆海社会经济关系的研究进展,并指出未来陆海社会经济关系研究应突破现有的研究视角与方法;加强陆海社会经济统计指标体系的构建研究;注重陆海社会经济不同尺度下的时空序列研究;强化陆海社会经济战略下综合性管理监督机制;同时优化其理论体系的构建,注重实践性与对比性的研究。     

渤海海峡跨海通道建设对城市经济联系的影响分析

渤海海峡跨海通道建设将极大改变环渤海乃至整个东部沿海的交通格局,势必对其目标城市大连、烟台带来直接的经济影响,同时也会对辽东半岛、山东半岛乃至东北、华北和华东不同尺度地区的经济联系产生深远影响。文章选取山东省17个和辽宁省14个地级市的地区的生产总值、城市人口以及城市间的最短时间距离等指标,测度渤海海峡跨海通道建成前后,对山东、辽宁两省区域城市经济联系的影响。研究表明:渤海海峡跨海通道建成后,对大连、烟台间的经济联系强度有显著提高,各城市经济联系度的平均增幅明显不同;同时,受距离衰减规律的影响,两省的城市分别以大连、烟台为中心,根据距离远近及城市自身发展程度分为4个层次,经济联系强度由内向外逐层次减弱;从整体上看,渤海通道的建设对带动两省城市之间的经济联系度都有大幅度提升。
