This study attempts to construct an econometric model using China's natural disaster losses and macro-industry development data from 1980 to 2017 to explore the macroeconomic fluctuations caused by natural disasters. The structural vector autoregressive (SVAR) and the seemingly unrelated regression (SUR) models are employed in estimating the impact of natural disasters on China's macroeconomy and how the disasters specifically affect the three sectors of the economy: primary, secondary, and tertiary. This study concludes that even though natural disasters in China do not significantly affect the overall real GDP, they have adverse impacts on the production in the primary industry, causing a sudden reduction in the means of production in the market and directly affecting various industries, but the impact on the secondary and tertiary industries is weak. This study also shows that the effect of natural disasters on the primary sector reduced significantly following industry restructuring after China's accession to the World Trade Organization (WTO). The impact of natural disasters on the primary industry could be reduced by adjusting the industrial structure to deal with macroeconomic shocks caused by natural disasters in order to promote macroeconomic stability of both regional and national economies. Finally, national aid policy should focus on the primary industry since that sector is significantly affected by natural disasters shocks.
本研究试图利用中国 1980 年至 2017 年的自然灾害损失和宏观产业发展数据构建计量经济学模型,以探讨自然灾害对宏观经济的影响。本研究采用结构向量自回归(SVAR)和似不相关回归(SUR)模型,估计了自然灾害对中国宏观经济的影响,以及灾害对经济的三个部门(第一产业、第二产业和第三产业)的具体影响。本研究得出的结论是,尽管中国的自然灾害不会显著影响总体实际 GDP,但它们对第一产业的生产有不利影响,导致市场上生产资料突然减少,直接影响到各个行业,但对第二产业和第三产业的影响较弱。本研究还表明,中国加入世界贸易组织(WTO)后进行产业结构调整,自然灾害对第一产业的影响显著降低。通过调整产业结构来应对自然灾害对宏观经济的冲击,可以减少自然灾害对第一产业的影响,从而促进区域和国家经济的宏观经济稳定。最后,国家援助政策应侧重于受自然灾害冲击影响显著的第一产业。
