ABSTRACTSince the Belt and Road Initiative (BRI) has been implemented for five years, it is time to ask whether the BRI contributes to Belt and Road (BR) countries’ economic growth, and how are the five elements of connectivity implemented between China and its partner countries since the BRI was proposed. This study focuses on the development of the five elements of connectivity between China and the BR countries from 2008 to 2017 using a comprehensive connectivity index extracted from principle component analysis, and then investigating if the connectivity has contributed to the economic growth of the BR countries with quantitative analysis of the fixed effect econometrical model. It is found that Russia, South Korea, and Singapore presented the top three levels of connectivity with China with regard to the overall connectivity index, varying from 1.4 to 2.4. Madagascar and Panama have the lowest level of connectivity with China, with values of ?0.8 to ?1.1. The result of the fixed effect model shows that the connectivity of the BR countries with China contributes to their economic growth. This provides quantitative evidence that the connectivity between BR countries and China has a significant influence on the economic growth of those countries. 相似文献

This paper investigates the impact of China's city size and urban population concentration on city productivity by developing a distinctive index based on global nighttime light data. Using the panel data of 280 prefecture cities from 2004 to 2013 and employing dynamic system generalized method of moments and panel threshold model regression techniques, our results show that city size has a positive impact on city productivity; therefore, cities in China still have the potential to expand. While moderate urban population concentration can benefit city productivity, excessively concentrated urban population distribution may impede the growth of city productivity. We also find that the level of labor income significantly affects the impacts of urban agglomeration on labor productivity. Therefore, our results imply that city development policies should focus more on how to appropriately allocate economic activities and adjust population distribution in urban areas according to different stages of economic development. 相似文献

Cross‐country comparison reveals an unusually small service sector in China. Using firm‐level data from China's 2008 economic census, we find two facts that speak to a novel mechanism of misallocation within service and between manufacturing and service sectors. First, compared with the manufacturing sector, there are more state‐owned enterprises and fewer entrants in the service sector. Second, markups increase with firm size, and the increase is more dramatic among service firms. We interpret these facts through the lens of a monopolistic competition model with heterogeneous firms and variable markups. A multisector model shows a new channel that translates asymmetric barriers to entry across sectors into sectoral markup differences, which in turn cause sectoral misallocation. Quantitative analysis shows that when reducing entry barriers to service firms to the extent observed for manufacturing firms, the model predicts a 12‐percentage‐point increase in the service employment share. 相似文献
