Operation optimization is a critical issue in the management of the multi-source large-scale urban centralized heating system (UCHS). A major challenge is to deal with the complex topological structure of its heating network. We investigate the operation enhancement of UCHS from the view of...

This paper is concerned with selecting important covariates and estimating the index direction simultaneously for high dimensional single-index models. We develop an efficient Threshold Gradient Directed Regularization method via maximizing Distance Covariance (DC-TGDR) between the single index...

In this article, we study a nonparametric approach regarding a general nonlinear reduced form equation to achieve a better approximation of the optimal instrument. Accordingly, we propose the nonparametric additive instrumental variable estimator (NAIVE) with the adaptive group Lasso.We...

Like most other developing countries, China experiences huge migration outflows from rural areas. Their most striking characteristic is a high geographical and temporal mobility. Rural migrants keep going back and forth between origin villages and destination areas. In this paper, we show that...

This paper examines the influence of family human capital on offspring's economic status in post reform rural China by concentrating on the father-son relationship. We focus on two indicators of family background: family class origin (jiating chengfen) and occupational experience. The results of...

Harmonised microdata show a Gini coefficient for per capita total income of 45.3 percent in China 2002 and 33.6 percent in Russia 2003. A much larger urban to rural income gap in combination with a much smaller proportion of people living in urban areas in China are important reasons for this...

Authors of this paper trace the influence of the 2008 global crisis and the impact of the subsequently implemented stimulus package on the characteristics of migrant flow in China until 2012. They analyze the consequences of the temporary but dramatic economic set-back on migrant employment and...

This paper examines underlying factors that could explain the decline in income inequality in the People's Republic of China (PRC) since 2008 and inquires whether the decline indicates that the PRC's income inequality has peaked following the Kuznets hypothesis. The paper first identifies four...

Two precisely comparable national household surveys relating to 1988 and 1995 are used to analyse changes in the inequality of income in urban China. Over those seven years province mean income per capita grew rapidly but diverged across provinces, whereas intra-province income inequality grew...
