异质性会影响城市间价格差异吗?——基于ESTAR模型的收敛性分析

Inter-regional price differences reflect the degree of market segmentation. This paper focuses on the heterogeneity factors, such as location, size, which impact on the price differences .We divided the CPI sub-items of 36 cities by local production, and verified the nonlinear variation features for price differences by Exponential Smooth Transition Autoregressive (ESTAR) model. The conclusions are as follows: the most cities' price differences are convergent, about 50% of the cities in line with the nonlinear of the lower the price deviation, the slower the convergence rate; the heterogeneity has significant impact on price differences, low transaction costs causing big cities (coastal cities)to have higher convergence ratio than small cities (Mainland cities), but the high labor and living cost making the convergence ratio of locally-produced Commodity in big city become lower. The results illustrate that the labor and living cost are becoming a major source of price differences between cities, which also hinder the market integration process, and transport costs at least no longer important in big cities.     

"农民工"平等权的宪法保障

农民工的权利平等是一个宪法问题,其基本权利的保障必须在宪法层面上予以解决,即农民工的权利应当得到国家政府的平等关切;农民工平等权利需通过宪法诉讼与宪法救济加以实现;国家需修正分配平等的理论与政策;废除农民工的观念歧视.     

Choice as Everyday Politics: Female Palestinian Citizens of Israel in Mixed Cities

The paper analyzes everyday life as an arena of politics and choice as a form of everyday power. The paper discusses the theoretical debate on choice and everyday life as depoliticization mechanisms and claims, as opposed to the prevailing theory, that choices made in everyday life form politics of small things. In the various choices that women make and the way they conduct their everyday lives, they offer an alternative sociopolitical order based on a conscious, intentional choice. The experience of Palestinian woman citizens of Israel living in cities of mixed Jewish and Palestinian populations serves as the field of study. I argue that the choice to live in a mixed city and everyday life in this city constitutes an alternative life space for Arab–Palestinian women that allows them to express their opposition to both their own society and the larger Jewish society and, at the same time, serves as a setting for social change. Arab–Palestinian women utilize the space of the mixed city to forge new ways for themselves and their families to structure gender relations, feminine identity, class identity, and Palestinian national identity in a largely ethnonational and gendered unequal society.

21世纪内陆城市治安运行机制探析

21世纪内陆城市面临的犯罪一是案件连续递增 ;二是暴力程度加剧 ;三是职业犯罪增多 ,群体性和流动化趋势明显 ;四是犯罪类型翻新 ,智能化发展趋势突显。面对严峻的犯罪形势 ,我们必须深刻审思治安运行机制中的欠缺 ,在把握欠缺的基础上 ,构建新的治安运行机制 :以指挥中心为核心 ,形成统一高效的接警处置机制 ;以巡警为骨干 ,强化社会面的动态控制 ;组建点、线、面相结合的堵控点 ,遏制流窜犯罪 ;拓展侦破途径 ,强化先发制敌的威慑功能 ;改革人口管理方式 ,突出重点人口和外来人口管理

LOCATING THE VANGUARD IN RISING AND FALLING HOMICIDE RATES ACROSS U.S. CITIES*

This research examines trends in U.S. homicide rates at the city level during the so‐called homicide epidemic in the latter decades of the 20th century. Using spline regression techniques to locate structural breaks in city‐level time series, we model the true trends of homicide rates to identify those cities that exhibited a meaningful boom and bust cycle. We then use Tobit regressions for all cities at risk of experiencing a cycle to estimate unbiased effects of theoretically important predictors on the timing of the phase changes. Our findings reveal that larger cities were more likely to experience an epidemic‐like pattern, and that densely populated cities characterized by high levels of deprivation tended to exhibit the rise and fall in homicide rates earlier than other cities.     

市民的依法行为:依法治市的一个重要方面

市民的依法行为和公务员的依法行政构成了依法治市的两大层面。市民的依法行为在依法治市中起着重要的作用。完善相关立法是市民依法行为的前提;鼓励市民依法参政、议政,以推进城市政治生活的民主化进程;弱化传统权威和单位权威,强化崇尚法治权威;培养法治精神,形成法制环境,使市民自觉学法,守法和用法
