Professor Jiang was a visiting scholar 2017-18. His general research interests include demographic analysis and public policy, sex structure imbalance and its consequences. Based on his previous work, he worked on the following two points during the academic visit at the Paul and Marcia Wythes Center on Contemporary China. The first was to examine the decline in China’s fertility level with decomposition method, and will devise decomposition formula to decompose the decline in fertility during the past several decades into the quantum effect (measured by marital fertility rate) and the tempo effect (measured by age-specific marriage proportion), as well as sex structure and age composition. The other is to examine to what extent sex-selective abortion contributes to China’s high sex ratio with Bayesian analysis. He received his PhD in Management Science and Engineering at the Xi’An Jiaotong University in 2006.
