从绿色奥运物质和意识两方面分析发展绿色营销,形成绿色物流管理系统是国际奥委会的政策导向和2008北京绿色奥运的需求。本文分析了绿色奥运的含义及绿色营销与绿色物流的理论基础,并提出发展绿色营销和绿色物流管理的策略。     

广州市外来人口的空间分布变动分析

利用第三、四、五次人口普查资料,对广州市外来人口空间分布进行分析。1980年代以来广州市外来人口在数量急剧增长的同时,其空间分布格局也发生了根本变化,即由原来主要集中于中心区转向主要集中于近郊区,并逐渐向远郊区延伸。针对外来人口的空间变化规律,提出了加强城市人口管理和城市规划建设的建议。     

工业智能化对社会经济发展影响的研究趋势

作为第四次工业革命的核心,工业智能化将对社会生产产生颠覆性影响。在全球经济形势不断收紧的当下,世界主要国家不断加大智能生产设备研发投入,旨在通过智能革命实现经济新一轮跃升。对于发展中的中国而言,加速推动工业智能化改造是快速实现经济发展高质量转型,抢占经济发展先机,实现经济赶超的重要途径。在综合梳理工业智能化相关研究文献的基础上,从工业智能化引致的生产效率、劳动就业、收入分配以及产业结构变动出发,系统梳理工业智能化相关研究综述,在此基础上总结当前工业智能化相关研究的不足,并进一步分析该领域可拓展的研究方向。     

How should we divide the pie? Equity distribution and its impact on entrepreneurial teams

Drawing on a multiple case study approach and data on eight entrepreneurial teams observed over six months this article develops a dynamic model of the consequences of equity distribution among team members. Perceived justice of equity distribution emerged as a key variable influencing entrepreneurial team interactions and important entrepreneurial outcomes. High perceived justice triggered positive team interaction spirals, whereas low perceived justice triggered negative interaction spirals. Teams exposed to external threats drifted from a positive spiral to a negative spiral despite high perceived justice. We discuss the implications of our study for research on entrepreneurial imprints, justice, and exit.     

宽带随机混沌雷达高速目标速度估计与成像

随机混沌具有真随机性、对初值敏感、易于产生和控制等特点,频率步进信号易于工程实现和处理,结合两者的优势,提出了一种载频随机步进的随机混沌信号(RSCFSCS)模型,用于高速目标的速度估计和距离维高分辨成像。首先,通过非周期函数激励非线性系统,产生不可预测的随机混沌信号(SCS),经频率调制后用作基带子脉冲。同时,将SCS通过映射变换得到跳频编码(FHC),用来决定调频脉冲串的载频步进。RSCFSCS 速度估计包括粗搜索和精搜索,粗搜索采用固定步长,保证速度偏差小于速度分辨单元,而精搜索采用黄金分割搜索算法可得到精确的速度估计。最后,子脉冲经相干合成形成宽带信号,实现高分辨距离成像。数值仿真表明提出的信号模型和处理算法性能良好。

江西省耕地后备资源潜力分布及开发组合序列分析

[目的]根据耕地后备资源的分布特征研究其开发组合序列是有效开发利用耕地后备资源、补充耕地的重要前提。文章利用江西省耕地后备资源调查评价成果,以县为分级单元对全省耕地后备资源进行开发潜力分级,对江西省耕地后备资源开发组合序列进行研究,从而为江西省耕地后备资源的开发顺序提供参考。[方法]利用Arc GIS空间图形分析法、DPS数据处理系统两维图论聚类等方法确定开发潜力等级以及开发序列。[结果]江西省耕地后备资源开发潜力从高到底依次分为Ⅰ级潜力区、Ⅱ级潜力区、Ⅲ级潜力区和Ⅳ级潜力区,面积分别为2.726 672万hm~2、2.306 897万hm~2、2.873 594万hm~2、1.378 88万hm~2。[结论]根据两维图论聚类法分析结果得知,江西省各县地域相似程度较高可优先开发的组合有进贤县-南昌县-余干县-鄱阳县-彭泽县;袁州区-分宜县-上高县-渝水区-樟树市;进贤县-南昌县-余干县-鄱阳县-都昌县和樟树市-渝水区-上高县-高安市-奉新县-安义县-永修县等。     

The economic effects of the 1920 eight-hour working day reform in Sweden

In 1920, the working day in Swedish manufacturing and services was cut from 10 to 8 hours without wages being cut correspondingly. Since workers demanded and got the same daily wage working 8 hours as they had with 10, real hourly wages increased dramatically; they were about 50% higher in 1921–1922 than they had been in 1919. This is the largest wage push in Swedish history, and this paper studies the consequences for profits, investments, capital intensity and unemployment. In traded manufacturing employers responded by increasing capital intensity and did not compensate for rising wages by raising prices, which led to a combination of jobless growth and low profit rates in the 1920s. Firms in non-traded manufacturing and services could raise prices and conserve profitability to a higher degree. In total, the effects of the reform were pro-labour. We discuss the implications for our understanding of interwar wages and employment, the literature on the decrease in inequality found in most industrial countries around 1920 and the rise of the ‘Swedish model’ in the 1920s and 1930s.     

Migration,self‐selection and income distributions

Self‐selection in rural–urban migration is examined using three datasets from rural and urban China in 2002. We construct a migrant sample including both migrants who converted their hukou status from rural to urban (permanent migrants) and those who did not (temporary migrants). We find a strong positive selection for permanent migrants, but the selection for temporary migrants is ambiguous. We reach these conclusions by comparing migrants' counterfactual wage densities, assuming they are paid as rural local workers, to actual wage densities of rural local workers. Our results imply that permanent migration has negative effects on rural human capital accumulation and income levels.
