Study on the Distibution of Migrant Workers＇ Destination -A Case Study of Henan Province

务工目的地选择是农民工空间流动的基础,对其研究有助于在微观层面上了解农民工流动的空间规律。通过对随机分层抽样产生的河南省11个不同类型样本村的实证研究,发现务工目的地大分散、小集中,县内和省外占较大优势。务工者主要集中于东部经济较为发达的省市,中部作为务工源并未形成最核心的务工区域。影响农民工务工距离选择的主要因素是年龄、家庭人口、人均耕地、村经济发展水平、村地形、村交通、离最近城市距离、关系网络等因子。从务工目的地角度观察,在省域尺度上,综合考虑务工目的地经济发展水平和务工距离的务工引力系数在较大程度上解释了农民工对务工目的地的选择,经济较发达、距离较近的目的地是务工者的首选。     

Estimating the Economic Value of Statistical Life in China： A Study of the Willingness to Pay for Cancer Prevention

This paper reports the results of a Contingent Valuation （CV） study on cancer prevention where Multiple-Bounded Dichotomous Choice （MBDC） questions are asked of rural residents in China about their willingness to pay （WTP） for a hypothetical cancer vaccine which is expected to be effective for one year. The WTP data are analyzed with region-, age- and gender-specific cancer morbidity and mortality risk statistics; an upper and lower bound of the Value of a Statistical Life （VSL） are then estimated. The estimated VSL is between 481 and 814 thousand yuan （or 58 and 98 thousand US dollars） at 2000 constant prices, which is compatible with the results of previous studies.     

Rural-Urban Continuum Problem＇s Origin and Its Development Strategy Change——A Case Study of Beijing

北京城乡结合部的政策制定目标经历了从单纯＂生态保护＂向＂生态保护＂、＂社会治理＂兼顾的转变过程,目前仍然遗存了诸多问题,而基于＂低价值判断＂的＂被动整治＂策略是问题的根源。为此应采取＂主动提升＂策略,重新审视该地区的综合价值,主动吸纳面向国际、适宜在该地区发展的高端功能,＂以功能带动价值,以价值带动整治＂,将＂功能提升＂、＂生态保护＂、＂社会治理＂三个目标捆绑解决,在＂发展＂中解决问题。在此基础上,对北京城乡结合部的空间形态、规划理念和政策保障提出了建议。     

A research on the evolvement of industrial structure and economic growth of He＇nan Province, China

This paper, based on the investigation of the statistics in the years of 1980-2005, using Shift-Share Method model, studies systematically the relation between the evolution of industrial structure and regional economic growth in five economic regions in He＇nan to offer the foundation of policy for optimizing the industrial structure and promoting regional economic development in phase, and thereby comes to the conclusions： （1） the industrial structure level of He＇nan, in comparison with the evolution of the industrial structure across the country, remains low, but yet the evolutional tendency of industrial structure in He＇nan complies with the Clark taw of the industrial structure evolution; （2） the spatial difference of He＇nan industrial structure evolution is comparatively large, （3） the evolution of industrial structure in He nan that influences economic growth can be categorized into three types： in eastern and southern regions, the shift-share of the industrial structure is negative, and the shift-share model of competitiveness is negative, in western and central regions, the shift.share of the industrial structure is positive, and the shift-share model of competitiveness is positive; in northern regions; the shift-share of the industrial structure is positive, and the shift-share model of competitiveness is negative： （4） the evolution of industriai structure influences greatly the development of the regional economy of He nan As the results of the researches shown, it can innovation of He＇nan tra：ditional industry with high-tech the vast development of the tertiary industry, the expansion of He＇nan overall level o industrial structure, the growth of deep-processing manufacturing of agricultural products, and the increase of He＇nan agricultural products subsidiary value Will be the strategic choices of the rearrangement of He＇nan industrial structure.     

A GWR-Based Study on Spatial Pattern and Structural Determinants of Shanghai＇ s Housing Price

利用上海市外环以内2010年12月1014个小区的平均房价数据,通过构建地理加权回归模型,并与基于全局最小二乘法（OLS）进行比较,揭示上海小区房价的空间分异和不同影响因子的影响。研究发现,每增加或减少一个单位各影响因子对房价的影响大小依次为：建成时间,到CBD距离,绿化率,到公园距离,距地铁站距离,距超市距离和距学校距离。同时,地理加权回归分解成局部参数估计优于OLS提供的全局参数估计,它可以深刻的揭示出房价和空间影响因子之间复杂的关系,而且可视化的工具可以用地图的形式更详细的呈现出城市房价的整体景观,这些都是传统OLS无法比拟的。
