生物多样性下降对产业链安全及金融稳定的影响与启示

生物多样性为人类经济社会发展提供重要支撑,但全球经济活动导致生物多样性不断下降。生物多样性下降会通过生产、销售、投融资等环节影响产业链供应链安全稳定,导致产业链供应链受阻或断裂,企业面临投资合规风险或资产价值损失、融资困难,相关风险甚至会传导至金融领域。为防范生物多样性下降对产业链安全及金融稳定的潜在风险,本文建议:一是强化全社会各主体的生态环境保护意识及主体责任,建立和完善相关制度;二是发展绿色产业链供应链,增强产业链供应链发展韧性;三是加强对生物多样性保护的财税和金融支持,引导更多社会资本进入生物多样性保护领域;四是加强生物多样性保护的国际合作,推动“一带一路”倡议与联合国2030年可持续发展议程深入对接。

Measurement of Urban Economic Gravity of China’s Three Major Agglomerations and Its Implications for the Coordinated Development of the Beijing-Tianjin-Hebei Region

This paper adopts the perspective of urban economic linkage and the modified urban economic gravity model to conduct a comparative analysis of the economic gravity among cities in China’s three major urban agglomerations,including the Beijing-Tianjin-Hebei region,the Yangtze River Delta,and the Pearl River Delta.The results show that,despite the ever-tightening economic linkages among cities in the urban agglomerations,the development of the Beijing-Tianjin-Hebei region falls behind that of the Yangtze River Delta and the Pearl River Delta in terms of coordination,closeness,and balance.The economic linkages among cities in the Beijing-Tianjin-Hebei region are not as cohesive as they could be and display a significant“siphon effect”through Beijing and Tianjin as well as a prominently unidirectional economic flow.This study suggests that efforts should be put into directing the orderly flow of resources from Beijing and Tianjin to cities in Hebei and promoting a balanced economic flow among cities,thus facilitating the coordination of regional development.
