‘Head-Swapping’ for Coal Trucks: How Henan’s Clean-transport Push Created a Rent-seeking Bottleneck

In Henan province, some factories have started to bar National VI diesel and gas tractors from entering their gates unless those trailers are towed by electric tractor heads, prompting a small rental market charging 200–400 yuan per swap. Provincial environmental authorities say the bans exceed official policy and have launched on-site investigations, highlighting a policy implementation gap between ambitious clean-transport targets and last-mile logistics realities.
