摘要｜Abstract

We investigate the networks of industry based on the volatility of value-weighted and equal-weighted portfolios from 1927 to 2017. The network structures measure the relationships of risk spillover between industries through adopting the method of generalized variance decomposition to estimate the comovements of volatility of industry portfolios. The static analysis of whole sample shows the industry of durable goods, energy and telecommunications are risk receivers, and industry of nondurable, manufacturing and other send the uncertainty to others. The dynamic analysis of rolling window presents the development of relationships of risk spillover between industries. The industry of telecommunications switches from a risk receiver to a risk sender after 2000. Finance industry becomes the biggest source of risk spreading to others during the financial crisis of 2007-2009, while the industries of real estates, utilities, shops, energy such as coal and oil have a short-term decline in total direct connectedness.
