城市内部不同所有制制造业区位时空演变研究——以无锡为例

制造业发展及其区位演变是中国近30年来城乡空间发展的主要动力,不同所有制制造业区位变迁是解读经济体制改革作用于城乡空间发展机制的重要视角。基于1985、2004、2013年制造业企业数据,运用空间分析技术及计量模型,探讨无锡不同所有制制造业区位演变规律及其体制动因。结果表明:无锡制造业空间从以中心城区为主的"单中心"格局向以郊区为主的"多中心"格局演进,表现出显著的郊区化和空间不均衡特征,其中土地有偿使用的市场力量和各类开发区设立的行政引导是重要驱动机制,而区位通达性因素的影响相对较弱;不同所有制制造业的区位演变呈现出差异化的体制响应特征。本研究对无锡的产业布局优化和城乡规划具有重要参考意义。     

EXPLORING THE DETAILED LOCATION PATTERNS OF U.K. MANUFACTURING INDUSTRIES USING MICROGEOGRAPHIC DATA*

ABSTRACT We use a point‐pattern methodology to explore the detailed location patterns of U.K. manufacturing industries. In particular, we consider the location of entrants and exiters versus continuing establishments, domestic‐ versus foreign‐owned, large versus small, and affiliated versus independent. We also examine colocalization between vertically‐linked industries. Our analysis provides a set of new stylized facts and confirmation for others.     

REGIONAL CAPITAL FORMATION IN U. S. MANUFACTURING DURING THE 1970s

ABSTRACT The study quantifies the impact of changes in input prices on regional net investment in manufacturing. A neoclassical investment model is estimated for the nation and three regions: North, South, and West. The data base is pooled state observations for the period 1974-78. The regional elasticities of net investment with respect to both input prices and the technology index are computed. The results indicate that net investment is mare sensitive to changes in input prices in the South and West than in the North. The biased technical change affects capital formation the mast in the West.     

美国大都市区尺度上的工业区位研究

工业化和城市化之间的互动关系体现在都市区尺度上的工业区位上。本文在新经济地理学和城市地理学所揭示的产品差异化和城市集聚效应相互关系的基础上,通过区位熵分析、赫芬达尔-赫希曼指数,对美国工业区位与大都市区间的耦合关系进行实证研究。结果显示:集聚于大都市区核心区的往往是产品个性化和定制化程度较高的行业;位于大都市区外围区的大都是产品依赖于城市市场,但标准化程度较高的行业;传统制造业则往往位于非大都市区。多数都市工业的市场集中度较低,而大部分传统工业的市场集中度较高。这不仅印证了新经济地理学的理论推演和城市地理学的行业分析,而且对包括中国在内的转型国家城市及其产业发展具有重要的参考意义。     

CHANGES IN THE LOCATION OF EMPLOYMENT AND OWNERSHIP: EVIDENCE FROM CALIFORNIA*

ABSTRACT We use the National Establishment Time‐Series database to describe shifts in the geographic dispersion of employment and ownership of firms. Focusing on data on business establishments in California, and establishments anywhere in the United States that are owned by firms headquartered in California, we find shifts in the operations of businesses headquartered in California to other states. However, this shift has been offset by increased employment in the state by firms headquartered elsewhere, resulting in California's share of national employment holding quite constant. The evidence points to increasing geographic dispersion of firms' operations, especially in industries with lower communication costs.     

1980年代中期以来上海市住区区位衍化的特征

对住房建设市场化以来城市住区区位衍化特征的了解和认识,将有助于有关部门科学地编制和实施城市规划。利用上海市1980年代中期以来开发的住区项目的空间区位数据,分析了其住区区位衍化的特征。分析结果显示,上海市1980年代中期以来住区区位衍化特征大致可总结为7个特征,即集聚与扩散趋势并存,居住空间重构与分异并存,热点开发区位的变化和延续同时存在,中心城区住区再开发和郊区住区新开发同时繁荣,住区区位"沿边"聚集,住区沿交通指向发展,从"地段"到"板块"的跃升和优化。     

FERTILITY CHANGES IN CENTRAL ASIA SINCE 1980

Limited studies document the fertility changes in Central Asia. Using survey and official data, this study describes the fertility changes since 1980 in Kazakhstan, the Kyrgyz Republic, and Uzbekistan. I first consider the swift decline in fertility in the 1980s and 1990s through the analysis of Synthetic Parity Progression Ratios (SPPRs). SPPRs show that women still have at least one child despite economic difficulties and that the end of communism affected more the transition to higher-order births. These results are however influenced by economic and demographic factors specific to each country. I investigate then the fertility upturn that is observed since the early 2000s—an issue neglected so far by demographers. Results from the analysis of official and household data show that in each country, the recent fertility increase resulted from the increase of distinct birth orders and was concentrated in specific ethnic groups.     

20世纪90年代以来中国工业格局及其变化

本文从工业行业结构角度入手,以东中西为研究单元,结合全国30个省市,运用集中化指数、罗伦兹曲线等方法,分析1990年以来,中国工业行业格局和区域布局的变化情况,指出:东中西地区行业部门渐趋完备,但部门间发展不均衡程度加深;电子、机械类制造业在工业中的地位上升明显;工业对经济增长的贡献存在区际不平衡,东中西部地区依次减弱。

CHANGES IN THE RELATIVE EARNINGS GAP BETWEEN NATIVES AND IMMIGRANTS ALONG THE U.S.‐MEXICO BORDER*

ABSTRACT Using 1990 and 2000 U.S. census data, this study investigates changes in immigrant/native earnings disparities for workers in U.S. cities along the international border with Mexico vis‐à‐vis the U.S. interior during the 1990s. Our findings—based on estimating earnings functions and employing the Juhn‐Murphy‐Pierce (1993, JPE) wage decomposition technique—indicate that the average earnings of Mexican immigrants along the U.S.‐Mexico border improved relative to those accrued by their counterparts in the U.S. interior and by otherwise similar U.S.‐born Mexican Americans between 1990 and 2000. However, when comparing Mexican‐born workers to U.S.‐born non‐Hispanic whites, the immigrant border‐earnings penalty remained statistically unchanged.
