Zero ratio, as the name implies, is the ratio of the price of auto parts to the total sales price of the whole vehicle. According to foreign research data, about 300% of the zero-to-normal ratio is normal. If it is higher than 600% and 700%, it is obviously unreasonable and there is a suspicion of profiteering.
In April this year, the two associations jointly released the zero ratio of 18 domestically used models and the zero ratio of 50 vulnerable parts for the first time. Some models have more than 1200% of the zero ratio, which is shocking and directly exposes the long-term of China's auto industry. The drawbacks of existence.
After half a year, have the prices of these 18 models changed? According to the release, 11 of them fell, 5 increased, and 2 did not change. The Beijing Benz W204 with the highest zero ratio decreased from 1273.31% to 1172.65%, and Corolla dropped from 625.22% to 387.68%, the largest decline. Overall, the total price of these models was reduced by 1,424,658 yuan, a decrease of 5.72%.
However, although most models have lowered the price of parts, the main reason for the decline is the high-priced low-frequency parts. The low-value high-frequency parts are less expensive, and some even have price increases. For example, the total price of the engine and transmission of these 18 models has dropped by 293,162. Yuan, the front bumper, the rear bumper total price rose 620 yuan. Feng Jun, an expert from the China Automobile Maintenance Industry Association, pointed out that lowering the price of high-priced low-frequency components will cause a significant decline in the zero-to-round ratio of the automobile, but it will have a small impact on the cost of the vehicle, and even there will be a hidden increase. Most consumers will not Benefited from.
In addition, the two associations also announced the second batch of 18 domestically used models of zero ratio, the highest of which is Reynolds Proud 719.75%, the lowest is 230.98% of the Great Wall Tengyi C30.
