Abstract

This study analyzed how interdependence between China, Hong Kong, Taiwan and Singapore stock markets changed after the implementation of Shanghai-Hong Kong Stock Connect system using the EGARCH-GED model that allow simultaneous analysis of return and variability. Since the implementation of this system, the interdependence of Taiwan stock market with the Greater China stock markets has been weakened, and the interdependence of Singapore's stock market with the Greater China stock markets has not been exist. On the other hand, he interdependence between China and Hong Kong stock markets has been shown to be significantly enhanced since the implementation of this system. This is appears to be the result of improved conditions for Chinese and Hong Kong investors to invest in the two stock markets following the implementation of this system. Thus, considering the portfolio investment in the Greater China stock markets, the investors will need to develop their investment strategies in light of these facts that the weakening interdependence of the Taiwan and Singapore securities markets and the strengthening interdependence of the Chinese and Hong Kong securities markets.

본 연구는 후강퉁 제도의 시행 이후에 중국, 홍콩, 대만 및 싱가폴 증권시장 간의 상호의존성이 어떻게 변화되었는지를 수익률과 변동성을 동시에 분석할 수 있는 EGARCH-GED 모형을 이용하여 분석하였다. 후강퉁 제도의 시행 이후 대만 증권시장의 대중화권 증권시장과의 상호의존성은 크게 약화되었으며, 싱가폴 증권시장의 대중화권 증권시장과의 상호의존성은 존재하지 않는 것으로 나타났다. 반면에 후강퉁 제도의 시행 이후에 중국과 홍콩 증권시장 간의 상호의존성은 크게 강화된 것으로 나타났다. 이는 후강퉁 제도의 시행에 따라 중국과 홍콩 투자자들이 두 증권시장에 투자할 수 있는 여건이 개선됨에 따른 결과로 추정된다. 따라서 대중화권 증권시장에서의 분산투자를 고려할 때에는 대만과 싱가폴 증권시장의 상호의존성 약화와 중국과 홍콩 증권시장의 상호의존성 강화를 고려하여 분산투자전략을 수립할 필요가 있을 것이다.
