An Economic Analysis of China's Domestic Crude Oil Supply Policies C hina's domestic oil production has lagged the very rapid growth in domestic oil consumption observed since the beginning of the 21 st century, leading to a large, and growing, reliance on imports to meet demand. China's current market structure and regulatory environment, among other factors, impede further development of the country's oil industry, despite a number of policies aimed at protecting domestic producers. Using a short-run equilibrium model of China's oil and gas supply industry, calibrated to 2016 data, we assess the impact of market access barriers on China's domestic production. We find that: Lifting all import constraints could have increased China's import demand by around 0.29 million barrels per day (MMbbl/d) in 2016. Opening China's market to cheaper oil imports in 2016 could have saved approximately $2.8 billion, equivalent to 1.7% of the country's oil supply costs, primarily due to import substitution for 17.8 million metric tonnes (MMmt), or equivalent to 0.29 million barrels per day (MMbbl/day), about 9% of domestic production that operates uncompetitively (see Figure 2). Liberalization of the import regime improves the efficiency of oil logistics through better utilization of the country's existing pipeline network, leading to a $600 million decline in overall oil transportation costs.
