Based on New Economic Geography,this paper adopts simultaneous equations to analyze the influencing factors of labor mobility and the tertiary industry and the endogeneity between labor mobility and the tertiary industry using China′s provincial panel data from 2006-2009.Results show that economic income,development of the tertiary industry and economic openness are the major determinants of labor inflow.With the increasing of the rural net income and the decreasing of the gap between urban and rural areas,labor mobility is reduced;capital,labor and market factors promote the development of the tertiary industry;policy constraints obstruct the development of the tertiary industry,and the urbanization strategy in different development stages of different regions has different effects;and the interaction of the labor mobility and the tertiary industry leads to aggregation effect of labor in China′s eastern region.

This paper examines the problem of elder suicide in the context of societal aging and social change.Statistics in China show that more elderly people killed themselves in the years after 2000 than in the previous decade.Existing research shows that prolonged illness and family conflicts are the two leading causes of elder suicide in China as a whole.The present paper’s central argument is that the gap between elderly people’s expectation and the reality they face in their lives could ease or intensify the two leading causes of elder suicide in urban China especially,and therefore an analysis of relative deprivation is much needed.To this end,the lack of medical insurance and the factor of urban expansion will be discussed with reference to elder suicides in Chinese cities.
