Does increasing descriptive representation enhance substantive representation? While ethnic minorities are generally underrepresented in legislatures worldwide, they are overrepresented in China’s National People’s Congress. We show that overrepresentation of ethnic legislators does not result in greater substantive representation. Compared to their Han counterparts, ethnic minority legislators are less likely to sponsor bills, show no significant difference in submitting policy suggestions, and are reticent to propose legislation on ethnic issues. They face challenges in mobilizing sufficient signatures for bill sponsorship within delegations and in building cross-delegation policy coalitions. Ethnic fragmentation may hinder their ability to advance the policy agenda. Our findings suggest that institutional constraints and collective action problems may hinder ethnic legislators from achieving substantive representation.

Addressing poverty is paramount, aligning with the first Sustainable Development Goal focused on eradicating poverty in all its forms. While the effects of high-speed rail (HSR) on absolute poverty have been documented, its impact on relative poverty remains understudied. This paper examines the influence of HSR on household relative poverty in China through a quasi-experimental design. The main results are as follows: (1) The opening of HSR significantly reduced the household relative poverty by approximately 1.8 %. (2) This alleviation effect primarily transpires through the expansion of economic activities and employment opportunities. (3) Notably, the impact of HSR is more pronounced in lower-ranked, smaller cities and in the western regions of China. Moreover, households with migrant workers or those engaged in non-agricultural sectors derive greater benefits from HSR developments. Our results suggest that HSR opening could have contributed to China’s relative poverty alleviation. Policymakers can consider the role of transportation infrastructure in mitigating household relative poverty, especially for low rank cities, small cities and periphery regions in other developing countries.
