Abstract:
Growing role of natural gas as an effective policy choice has kindled the discussions surrounding the security of its supplies in the policy circles of the Chinese government. This study tries to evaluate China's natural gas supply security and employs a system-oriented modelling approach namely, Ecological Network Analysis (ENA) to integrate all the critical compartments of China's natural gas supply system. Several ENA indicators are constructed, which disclose that domestic natural gas production contributes significantly to China's natural gas supply system in comparison with all the external natural gas suppliers. In addition, the variations in a system stability indicator suggest that diversification of external natural gas suppliers has a positive influence on China's natural gas supply security. Furthermore, the results revealed that China's natural gas supply security policy is orchestrated on following features 1) to increase the investment in the upstream natural gas production sector to boost its domestic production in order to reduce its import requirements and 2) to diversify the external natural gas supplies by sources and routes to reduce the level of the economic and supply disruption related risks.
