Media reports of China surpassing the United States as the world’s biggest oil importer as shown by data from a U.S.government agency were somewhat overrated.Recently published data by the U.S.Energy Information Administration(EIA)showed that net imports of the United States and China stood at 6.24 million and 6.3million barrels per day in September of 2013,respectively.The EIA further forecast that China will start overtaking the United States by October 2013 on a monthly basis and by 2014 on an annual basis in terms of net oil imports. 展开更多

The existing oil import dependence index cannot exactly measure the economic cost or scales, and it is difficult to describe the economical aspect of oil security. To measure the foreign dependence of one country's economy and reflect its oil economic security, this paper defines the net oil import intensity as the ratio of net oil import cost to GDP. By using Divisia Index Decomposition, the change of net oil import intensity in five industrialized countries and five newly industrialized countries during 1971—2010 is decomposed into five factors: oil price, oil intensity, oil self-sufficiency, domestic price level and exchange rate. The result shows that the dominating factors are oil price and oil intensity; moreover, the newly industrialized countries have higher net oil import intensity than industrialized countries. 展开更多

Crude oil imports in China are mainly carried out by state-owned entities with non state-owned entities as compliment. Crude imported by 5 state-owned entities accounts for 90% of the total imports, while non state-owned entities are about given more freedom in using and importing crude. In 2015 only, there were 13 companies granted with access to imported crude oil and 6 were qualified to import rights. Currently, there are 29 non-state-owned companies engaging in crude import business. China oil market is faced with severe challenges. The growth rate of oil demand declined, and dependence upon imported oil increased and reached as high as 61.26% in 2015. Refined oil demand growth also slowed down, and oil refining overcapacity got prominent and completion would become fiercer in future. Overcapacity was about 140 million tons per year in 2015. Consumption ratio of diesel to gasoline went on declining, and the task of product structure adjustment was heavy. China oil market is undergoing great transformation, and institutional mechanism will go ahead, on the basis of centering on orderly release of limitations on crude oil and refined oil import and export, orderly release of competitive business and government pricing of oil/gas downstream links, vigorous resolving of overcapacity, strengthening low-carbon development, and laying a solid foundation for guarantee. 展开更多

In 2016,China's net imports of crude oil increased to 378.3 million tons and its net exports of product oil soared to 20.45 million tons.Refinery crude runs continue to grow at a low rate,and the domestic product oil market still has a supply surplus.Diesel consumption fell for the first time in 21 years.The liquefied petroleum gas(LPG) market continues to grow rapidly,spurred on by feedstock demand for chemicals and gasoline blending components,and imports of LPG have reached a record high of 16.12 million tons.The refinery throughput of Petro China and SINOPEC had declined for 2 consecutive years,but crude oil imports climbed to a new high of 381 million tons as independent refineries boosted their utilization of capacity and the domestic oilfields produced a decreased amount of output.Imported oil now accounts for more than 2/3 of the Chinese market compared to being only about 1/3 15 years ago.Moreover,the proportion of imported crude in refinery runs has risen to 70%.In 2017,China's economy will continue to face substantial pressure,and domestic demand for product oil will continue to grow slowly. 展开更多

Domestic economic growth slowed down and supply exceeded demand in oil market in 2015, so the growth of refineries' processing volume was limited. Nevertheless, the gradual decontrol of market and the storage requirement under low oil price, crude oil imports hit a record high of 335.5 million tons, with the growth rate approximating 9%. Refined oil exports soared and imports decreased, which made China become a net refined oil exporter for the first time for 24 years, and net imports reached 6.22 million tons. Robust requirement on chemical raw materials propelled imported liquefied petroleum gas market to go on expanding. Imports exceeded 12 million tons in 2015, thus China leaped into the world's largest liquefied petroleum gas importer. In 2016, oil consumption growth would be kept at lower level. However, China would further decontrol crude oil import and refined oil export permits and put incremental storage capacity into use. Therefore, crude oil imports would continue to rise up, and refined oil exports may hit a new historic high. Imported liquefied petroleum gas market will enter into a stage of stable growth after two years' rapid development. 展开更多

China's oil import dependence had risen to 72% in 2017, while its net imports of various oil products,including crude oil, refined oil, liquefied petroleum gas(LPG) and other products, had climbed to 418.8 million tons, an increase by10.7% over 2016. China's crude oil import reached 420 million tons, surpassed the United States for the first time, and China had become the biggest crude oil importing country in the world. Net export of the refined oil, mainly the diesel, continued to increase to 22.7 million tons, as driven by the oversupply situation of the domestic market. Last year, China's LPG import was 18.45 million tons, but its growth was diminishing.Oil price would continue to rise in 2018, while the domestic demand of refined oil would be maintained at a lower rate of growth. However, driving by new refining capacities to be brought online, it is estimated that the crude oil import would still be increased remarkably. LPG import would reach a new high due to the growth potential and strong demand for feedstocks in the petrochemical product market. 展开更多

Based on social network analysis and stochastic frontier gravity model, this paper studied the characteristic evolution and influence factor of oil import network between China and “Belt and Road” countries. Then by constructing a stochastic frontier gravity model including the crude oil future price and oil importing price, it found that the international crude oil future price, the oil importing price, the political situation, the trade agreements have the effects on the China's oil import from “Belt and Road” region. It provided suggestions for improving the spatial pattern of China's petroleum trade. 展开更多

Concerns about China’s energy security have escalated because of the country’s high dependency on oil and gas imports, so it is necessary to calculate the availability of domestic oil and gas resources and China’s ability to obtain foreign energy through trade. In this work,the calculation was done by using the energy return on investment(EROI) method. The results showed that the EROIstnd(i.e., standard EROI) of China’s oil and gas extraction decreased from approximately 17.3:1 in 1986 to 8.4:1 in 2003, but it increased to 12.2:1 in 2013. From a company-level perspective, the EROIstnddiffered for different companies and was in the range of(8–12):1. The EROI2,d(EROI considering energy outputs after processed and direct energy inputs) for different companies was in the range of(3–7):1. The EROI of imported oil(EROIIO)declined from 14.8:1 in 1998 to approximately 4.8:1 in 2014, and the EROI of imported natural gas(EROIING)declined from 16.7:1 in 2009 to 8.6:1 in 2014. In 2015, the EROIIO and EROIING showed a slight increase due to decreasing import prices. In general, this paper suggests that from a net energy perspective, it has become more difficult for China to obtain oil and gas from both domestic production and imports. China is experiencing an EROI decline, which demonstrates the risk in the use of unsustainable fossil resources. 展开更多
