A recent investigation by the Ministry of Finance into government subsidies for new energy vehicles revealed five manufacturers of such vehicles, including two in Suzhou, East China's Jiangsu province, got the subsidies through deceptive means.

Gemsea, a new energy vehicle-maker in Suzhou, cheated the government of 261.56 million yuan ($39 million) in subsidies by claiming to have sold 1,131 such vehicles by fabricating materials purchase documents, and original papers of vehicle sales and registration. Another company in Suzhou fleeced the government of an extra 519.21 million yuan in subsidies by issuing registration certificates for 1,683 vehicles that, in fact, it had failed to assemble by the end of 2015.

The other three companies used similar means to cheat the government.

The government has taken appropriate measures to retrieve the swindled funds, and barred a couple of the companies from getting the subsidies. But such punitive actions are not enough to end such deliberate and organized fraudulent acquisition of government subsidies by new energy vehicle-makers. Those responsible for the fraud should be held accountable.

Besides, the fraud also makes it necessary for the government to reflect on the limitations of its long-existing industrial policy. The adoption of preferential or supportive programs for certain industries may be necessary to distribute resources efficiently when the market-based mechanism for resource distribution doesn't work properly. But the presence of a visible government hand usually makes it difficult for certain industries to develop in a healthy manner.

There is no reason to believe government officials have a sharper sense of market trends than entrepreneurs. Government officials cannot predetermine or preplan the development of any industry because they may be high on theoretical knowledge but lack entrepreneurial acumen.

The supportive policy offered to a certain industry is like risk investment that may or may not fetch returns. Innovation should be encouraged in all industries, but distorted incentive policies should be stopped.
