矿业城市生命周期与空间结构演进规律研究

在对矿业经济和城市发展生命周期判定的基础上,选取石油城市大庆、有色金属城市金昌、煤炭城市大同等典型矿业城市作为研究样本,梳理矿业城市发展生命周期,重点研究矿业城市空间结构有序化演进的一般规律。文章认为矿业城市经历"矿业经济-新型制造业-综合性"的完整发展过程,城市空间结构对应整体演进过程也呈现出"矿业经济的点状离散-新型制造业的分区极化-综合性城市的多组团圈层"的阶段性特征。在矿业经济时期内部又呈现"导入期、成长期、成熟期、衰退期/转型期",且对应不同阶段在城市人口、职能、经济结构等方面均呈现不同的特点。矿业城市空间演进整体上体现出"矿业经济是空间发展的初期主导,空间结构随城市职能的升级而演变,空间作用呈现集聚与分散的交替"的有序化发展规律。     

中国当代人口城市化、空间城市化与社会风险

趋势和比较分析我国人口城市化和空间城市化,表明我国人口城市化的速度和规模远滞后于空间城市化。其实质为社会、文化、制度的构建与经济增长的不同步,究其缘由,除了政策制度的因素外,资本和权力的勾连以及"经济达尔文主义"是其"质料因"和"动力因"。这种对城市化经济性的过度追求必将带来土地金融危机、社会极化、空间区隔和"原子化社会",使生活在城市中的人缺乏尊严感和安全感,集聚社会风险。因此,城市化发展应从规模的追求转向到对质的追求,构筑一种"城市如家"和"充满选择机会"的城市化。     

Employment Dynamics,Spatial Restructuring,and the Business Cycle

The multinodal metropolis is an evolving system, affected by both long-term restructuring and by business cycle dynamics. This study of the Dallas-Fort Worth Metroplex points, first, to the multiplicity and wide dispersion of employment centers within the region and, second, to the importance of vintage. During business cycle upswings new centers in new and more dispersed locations receive the preponderant share of new growth. During business cycle downswings, old activities are pruned most heavily from old locations. The result is an increasingly complex array of specialized agglomerations.     

The Strategic Choice of Location and Transport Mode in a Successive Monopoly Model

This work emphasizes the incentives for vertical integration in a spatial model. A downstream monopoly will both strategically increase its transport costs and locate inefficiently relative to its customers. This forces the upstream monopolist to lower its input price rather than permit sales to decline. The excess costs and the inefficient location lower total profit in the vertical stream generating an incentive for vertical integration.

SPATIAL PRICING IN INTERDEPENDENT MARHETS*

ABSTRACT. Conditions for spatial price equilibrium are derived for a set of firms in oligopolistic spatial competition, distributed at fixed locations in a heterogeneous region where consumer purchasing patterns are a probabilistic function of the price distribution rather than a deterministic function of proximity to firms. The resulting prices vary with accessibility to consumers or with the degree of local spatial monopoly, and result in non-zero profits for firms. Conditions describing the existence and stability properties of this spatial price equilibrium are defined, and are shown to be equivalent for two different hypotheses concerning disequilibrium pricing behavior: a partial price adjustment model and a Bertrand game. For two different profit goals, total profit maximization and profit rate maximization, it is shown that a spatial price equilibrium exists and is at least locally quasi-stable.     

INCORPORATING TECHNOLOGY DIFFUSION,FACTOR MOBILITY AND STRUCTURAL CHANGE INTO CROSS‐REGION GROWTH REGRESSION: AN APPLICATION TO CHINA*

ABSTRACT This paper advocates a spatial dynamic model that introduces technology diffusion, factor mobility, and structural change into the cross‐region growth regression. The spatial setting is derived from theory rather than spatial statistical tests. An application of this model to the study of cross‐province growth in China over the period 1980–2005 indicates that incomes are spatially correlated, which highlights the significance of technology diffusion and factor mobility. Furthermore, the integration of neoclassical growth empirics and the structural change perspective of development economics provide a much improved account of interprovincial variations in income levels and economic growth.     

The Pricing of Delivery Services*

Abstract. Due to spatial separation between points of distribution and consumption, a vital feature of retailing is the provision of delivery services by customers, retailers, or transport intermediaries. Some store retailers, many Internet retailers, and most transport intermediaries use a multizone pricing plan or a generalized N‐zone menu plan. We extend spatial pricing theory to encompass multizone plans. We prove that the optimal number of zones varies with the level of demand relative to the spatial dispersion of customers, and with the cost of implementing a zonal plan. We show that a small number of zones capture almost all the profit attainable with a spatially discriminatory plan.     

REGIONAL LABOR PRODUCTIVITY IN THE NETHERLANDS: EVIDENCE OF AGGLOMERATION AND CONGESTION EFFECTS*

ABSTRACT This paper studies the impact of localization, urbanization, and diversification on regional labor productivity levels and growth. We find substantial effects, accounting for roughly half of the explained variation in the labor productivity differences within the Netherlands in the 1990s. Diversification, urbanization, and localization effects are significant and positive for productivity levels. These levels appear cointegrated. The error correction specification of productivity growth surprisingly reflects negative agglomeration effects. From the theoretical model it follows that congestion effects must have taken precedence over agglomeration effects during this period. Both agglomeration and congestion effects are dampened by job density in neighboring regions. Finally, policy simulations with the estimated model show that spatial concentration is more harmful to national productivity growth than spatial dispersion.     

SPATIAL DIFFERENTIATION OF POPULATION DEVELOPMENT IN A DECLINING REGION: THE CASE OF SAARLAND

We increasingly understand the causes of population decline: these can be, among others, processes of deindustrialization, decreasing fertility or the succession of a city through the stages of urban life as the city matures. However, we are still insufficiently able to explain why differences still exist between cities within regions experiencing the same macro‐processes and between cities of the same “level of maturity”. This research addresses this intra‐regional differentiation in population development in the declining former mining region of Saarland (Germany). Quantitative and qualitative analysis reveals that the differentiation in current decline stems from (1) the differentiated population development trajectories of the past, with a massive population boom followed by an aged and declining population in the industrial municipalities; and (2) the spatial distribution of amenities over the region; and (3) the spatial distribution and accessibility of housing opportunities steering migration flows. The latter are not necessarily concentrated in those areas that are attractive. Rather, the distribution of these housing opportunities strictly follows the planning logic of the supra‐local institutional framework, with a concentration of housing within easy access of major transportation infrastructure and in larger centres. The case study thus reveals that the mechanisms behind this intraregional differentiation are much more complex than often portrayed in the urban development and decline debate.     

交通区位演化与空间开发强度的时空协同关系及其弹性识别——重庆市案例实证研究

交通区位条件是反映区域发展潜力的重要指标,分析其与空间开发强度之间的时空协同关系对揭示区域发展的动力机制具有重要启示意义。以重庆市为例,通过指数建模、回归拟合及弹性系数等方法,揭示其间互动关系。研究发现：①研究区交通区位指数处于快速跃升阶段,区域差距有所缩小,空间集聚格局基本稳定;②空间开发强度指数数值整体偏低,增速差异较大,空间集聚格局呈单集聚中心向多集聚中心演进趋势;③不同类型的交通区位指数（内部、外部和综合）与空间开发强度指数均呈显著正相关,且关联性表现出不同状态;④交通区位演化与空间开发强度互动敏感程度较高,各弹性系数空间集聚格局基本一致,但其形成机理差异较大。     

Metropolitan Housing Subsystems: A Comparative Review

Population, household, and housing data of twelve cities in industrialized countries are compared with respect to different rates of growth or decline in the inner and outer parts of the urban area. The study shows that in nearly all metropolitan areas the core declines in terms of population, but less in terms of households, and is stable or grows in terms of dwellings. This phenomenon can be characterized as a process of “spatial substitution” from core to periphery which is fast in terms of population, but slow in terms of dwellings because of the inherent inertia of the physical stock of the city. Following Batten (1985), a logistic substitution model is used to compare the speed and duration of spatial substitution in the urban areas studied. It is found that the process is similar in most urban areas, but that the cities have reached different points along its course. The conclusion is that the residential deconcentration observed in most urban areas in industrial countries is mainly a consequence of overall population growth or decline, decreasing household size, increasing per capita consumption of floor space, and lack of land in the core.     

Comparison of two cluster life stages in a synthetic knowledge base

ABSTRACT

Knowledge flows in clusters are highly important since they are related to innovation. Types and spatial levels of knowledge sources have been studied by many scholars. This study examines knowledge sources from evolutionary perspective. Evolutionary Economic Geography suggests that regional industries and their dynamics co-evolve. While conceptual and empirical studies argue that network characteristics take different characteristics throughout time, and that knowledge sources are subject to change, little is known about in what way they change in a synthetic knowledge base. In this study, we examined the knowledge sources in a specific knowledge base throughout time. The study was applied to two clusters in Turkey in a synthetic knowledge base yet in different life stages: emergence and maturity. The network structure was analysed by social network analysis, hypotheses were tested by Mann–Whitney U-Tests. The findings show that although network structure and density change through maturity, the types and spatial levels of knowledge sources do not vary between the two life stages, they keep the same characteristics of their knowledge bases.

Coast Versus Inland: Two Different Queenslands?

To a degree unparalleled in any other major nation, Australia's society and economy shows a spatial dichotomy between a restricted but relatively well-endowed coastal strip and a vast, under-endowed interior. Much of the nation's economic history has been shaped by alternating phases of convergence and divergence in the relative fortunes of coast and interior. Queensland is the state which most clearly typifies this Australian dichotomy, the more so because of the high expectations placed on inland development and the recent strong impulse towards coastal growth and inland decline. The persistent and severe decline of the inland has been overshadowed by economic and demographic growth along the coast. The fortunes of the state are increasingly tied to the future of its coastlands.     

经济发展与住宅市场异速增长时空格局及其形成机理——以长三角地区为例

住宅具有重要的社会稳定功能,其市场发展状况与经济增长关系是实现城市更高质量发展和畅通国内大循环的关键。本文以GDP表征经济发展,住宅价格和租金表征住宅市场发展状况,利用空间变差函数、异速增长模型和增强回归树模型探究2008—2018年长三角地区三者的时空格局及演化机理。研究表明：(1)长三角地区城市经济规模、住宅价格和住宅租金空间格局具有较强的稳定性,呈现出“一极多核”形态。(2)在纵向和横向异速上,经济规模—住宅价格、经济规模—住宅租金均以负异速增长为主,前者异速增长系数多高于后者。(3)在影响三者异速增长的因素中,科技发展水平、财政投入水平、城市人口规模、设施供给水平、产业发展水平和城乡收入差距是经济规模与住宅市场异速增长的主导因素;经济、人口、社会和行政等因素影响的差异性,在预期因素的催化下,使经济规模—住宅价格异速增长高于经济规模—住宅租金。     

ZONE PRICING*

ABSTRACT. Our purpose is to study a spatial price policy often encountered in the real world, known as zone pricing. This price policy consists in determining simultaneously several delivered prices together with the geographical zones in which they apply. It is shown that zone pricing approximates perfect spatial price discrimination and that the firm's profit increases with the number of zones. Furthermore, the number of markets supplied by the firm rises with the number of zones. Finally, zone pricing is compared to other standard spatial price policies and possible extensions are discussed.

Spatial Spillovers and Regional Growth: A Cognitive Approach

Spatial spillover effects are widely studied in the literature, as an important source of externality and therefore of discrepancy between private and social optimum, creating the emergence for ad-hoc policy interventions. Within the literature, their spatially-bounded nature is highly emphasised, but the mechanisms for their spatial diffusion are generally considered as a black box, with no reference to territorialized channels through which these externalities spread around. The study aims to present a literature review on the spatial spillover concept, emphasising two main stages of reflection, the so-called spatial approach and the functional approach. This work identifies in a third approach, the cognitive approach, a new perspective to the interpretation of spatial spillovers and their conditions, and on this approach it elaborates theoretically and empirically. The main assumption is that the capabilities of economic agents to absorb and utilize spillovers—implicitly assumed by the spatial spillover theory to be invariant with respect to space—in reality highly depend on strongly territorialized and un-imitable assets, such as local trust, sense of belonging and creativity. This assumption is tested empirically on all NUTS 2 of the 27 European member countries, thanks to a regional forecasting growth model developed by the author, called MASST.
