I always wonder why gasoline(petrol) is so much more expensive in the HKSAR side of the border compared to mainland side. I thought Hong Kong is always known to be very anti taxation. Though for cars with dual Hong Kong/Canton plates they have the luxury of being able to fill up on the other side which is not too far away and drive back which puts Hong Kong fuel stations at a disadvantage as the border is so close by. Though gas(petrol) had skyrocketed on the mainland side since 2010. Back in 2008 Chinese gas(patrol) used to be cheaper than any station pump price found in the US. Now even with International oil prices at record lows Chinese gas(petrol) is still higher than all except expensive pump prices in US usually in Hawaii. I guess the rapidly increasing fuel consumption rate due to the explosive increase in car ownership the past few years and the deteriorating relationship between Beijing and China's major oil producer Xinjiang is to blame for the permanent spike oil costs in China and decreasing subsidies. Though prices still remain quite a bit lower than Hong Kong's prices.
I do wonder how taxi drivers in both Hong Kong and mainland survive with such low rates on the meter if petrol prices are this high. Taxis in other countries including the US charge rates many many times higher yet often turn a negative earning. I guess taxi owners in mainland took a big lose in earnings when fuel prices nearly doubled in a years or two notice given the regulated meter rates did not go up nearly as much to compensate for the increased fuel costs.
