Paired Assistance:Policy Rationale and Economic Performance as Illustrated by Xizang and Xinjiang

This study highlights the changing priorities of China’s paired assistance throughout the past decades,as well as its theoretical implications and economic growth effects for recipient regions.Using panel data from 32 prefecture-level cities from 1990 to 2020,this study uses the multiperiod difference-in-differences approach to examine how paired assistance has contributed to economic growth in Xizang Autonomous Region and Xinjiang Uygur Autonomous Region.The findings indicate that,first,the implementation of the paired assistance policy has boosted economic growth in Xizang and Xinjiang.Second,paired assistance has stimulated economic growth in recipient communities by improving infrastructure.Third,paired assistance has contributed to economic growth in recipient communities by providing improved public services such as education and healthcare.Improvements to public services have a relatively smaller indirect effect in short term than infrastructure development on economic growth.Yet both education and healthcare are crucial to people’s quality of life in recipient communities.This paper has refined and broadened research on the effects of paired assistance,providing preference for future policymaking.

Characteristics:Evidence from the“Enclave Economy”in the PRD Region

Paired assistance is an important means for developed regions to help lessdeveloped regions achieve common prosperity.Despite its advantages,governmentmandated paired assistance tends to be less effective due to the lack of economic incentives for assisting localities.Therefore,local governments in China have explored an incentivecompatible paired assistance model.Based on the paired assistance between cities in the Pearl River Delta(PRD)region and the eastern,western and northern parts of Guangdong Province,this study designed a natural experiment for the network relationship of paired assistance.Empirical results based on industrial and commercial registration data and land transfer data indicate that paired assistance has enhanced bilateral investment linkages,and that the inter-regional benefit sharing mechanism has incentivized assisting localities to provide paired assistance.Our heterogeneity analysis reveals that a shorter distance between assisting and beneficiary localities may lead to better results of paired assistance.This study contributes to the understanding of incentive mechanisms for local government cooperation and offers insights for balancing regional development and achieving common prosperity.

The Status Quo, Opportunity and Approach——the Development of Ethnic Minorities in the Context of the Belt and Road Initiative

Currently, China is advancing the Belt and Road Initiative, which creates a new opportunity of historical significance and provides guidance for the economic and social development of ethnic minority communities(particularly those in western China). Under the new historical conditions, it is necessary to innovate and improve China's regional aid policies and regional development strategies such as the "pairing assistance" and the Western Development, and organically combine them with the Belt and Road Initiative. In the meantime, China should revolve tightly around the internal and external "connectivity," and give full play to the functions of the "pairing assistance" policy and the "Western Development" strategy in a bid to boost the ethnic development of contemporary China within the framework of the Belt and Road Initiative.

National Health and Family Planning Commission Plans For the Implementation of Health and Poverty Alleviation Project

On 2016 March 24,National Health and Family Planning Commission(NHFPC)held the leading group meeting on poverty alleviation and pairing-assistance,which planned the implementation of 2016 health and poverty alleviation project.Li Bin,the group leader and minister of NHFPC,

Dynamically assisted pair production for scalar QED by two fields

By solving the quantum Vlasov equation, the dynamically assisted pair production for scalar quantum electrodynamics （QED） is investigated. It is verified that this mechanism still holds true for boson pair production. Two combinations of two electric fields having different time scales under various time delays are considered; it is found that the oscillations of the momentum spectrum and the number density of created bosons decrease with increasing time delay, and the latter has a maximum value when the time delay equals zero. Furthermore, the differences in vacuum pair production between bosons and fermions are also studied, and they are helpful for distinguishing the created bosons from fermions.
