For Lin Tianen, a restaurant owner in Shenzhen, the digital transformation of his business turned into a nightmare in a single afternoon. Without his consent, Meituan’s AI system bulk-edited fifteen of his signature dishes to a uniform price of 28.81 RMB, representing discounts of up to 48 percent. The backend system revealed a chilling detail: the 'platform cost' for these promotions was zero, meaning the merchant shouldered the entire financial burden of the sudden fire sale.
This incident is not an isolated technical glitch but a systemic feature of the evolving power dynamics in China’s gig economy. In cities like Foshan and Chengdu, merchants are reporting similar automated price 'adjustments' triggered by algorithms that detect lower prices on competing platforms. For many small business owners, the result is a surreal economic trap where higher order volumes lead directly to deeper financial losses, with some dishes selling for less than the cost of their ingredients.
While Meituan has touted its 'AI Guardian' tools for successfully intercepting millions of fraudulent claims and saving merchants millions in losses, the platform’s use of AI for pricing reveals a darker side of technological integration. The 'assistance' offered to merchants often comes wrapped in blanket legal authorizations. By signing 'operational support' agreements, vendors unknowingly sign away their fundamental right to set prices, allowing the algorithm to manipulate their storefronts under the guise of staying competitive.
Industry data highlights a staggering imbalance in the food delivery ecosystem. While consumers and platforms capture the lion's share of the value created by delivery services, merchants are increasingly squeezed. The China Chain Store & Franchise Association reports that some vendors now bear subsidy burdens as high as 70 percent, far exceeding the international norm of 30 percent. Those who resist, such as the Chengdu-based Shu Wei Xuan chain, often find their search rankings throttled, leading to a precipitous drop in daily orders.
This algorithmic squeeze has dire implications for public health and industry sustainability. When profit margins are obliterated by automated price wars, the first casualty is often food safety. To survive 'loss-leader' orders forced by the platform, some merchants are driven toward lower-quality ingredients, 'ghost kitchens,' and pre-packaged meals. What looks like a win for the consumer in the short term is, in reality, a ticking time bomb for the integrity of the food supply chain.
Regulatory pushback is finally beginning to materialize. The 'Internet Platform Pricing Behavior Rules,' set to take effect in April 2026, specifically prohibit platforms from using technological means to force 'all-net lowest prices' or manipulate merchant backends without explicit authorization. However, as the platform giants have shown a remarkable ability to mask coercion as 'technical services,' the battle for the autonomy of China’s small businesses is far from over.
