Anti-corruption Shocks, Relational Supply Chains, and Crowded Competition: Heterogeneous Impacts on Private Manufacturers and Sectoral Demand in China
This paper analyzes how China's provincial anti-corruption enforcement shocks, while dismantling relational rents, simultaneously trigger short-term supply chain fragility, demand contraction in luxury sectors, labor shifts to the gig economy, and unproductive market crowding in SOE-dominated industries, ultimately revealing a critical tension between institutional reform and economic stability.

For decades, the way businesses in China secured contracts and supplies often relied on a system of personal connections rather than just price or quality. In many industries, especially those dealing with government agencies or state-owned enterprises, success depended on building relationships through banquets, gifts, and informal networks. This approach, often called relational contracting, meant that a company's ability to get work was tied to its social ties with officials. When a massive anti-corruption campaign began in late 2012, it fundamentally changed this landscape. The government started investigating officials and punishing businesses that relied on these informal ties. While the goal was to clean up the system and make markets fairer, the immediate effect was a sudden shock to the way supply chains operated. This created a complex situation where the removal of old, corrupt habits caused new, unexpected problems for factories, workers, and the broader economy.
A team of researchers set out to understand exactly how this shock rippled through the Chinese manufacturing sector. They analyzed data from thirty-one provinces between 2020 and 2024, a period when anti-corruption enforcement varied significantly from one region to another. By comparing provinces with intense enforcement against those with lighter enforcement, they could isolate the specific effects of the crackdown. Their work reveals that while the campaign successfully reduced corruption, it also triggered a chain reaction of distress for private manufacturers, a drop in demand for certain luxury goods, and a shift of workers into the gig economy. The study suggests that the transition from a relationship-based system to a rules-based one is not smooth; it creates short-term pain before long-term benefits can take hold.
The researchers found that the hardest hit were private manufacturing companies that had built their business models on political connections. When enforcement intensified, these firms faced a sudden loss of access to government and state-owned enterprise contracts. The data shows that for every standard increase in enforcement intensity, the rate of financial distress among these private firms rose by 4.2 percentage points. Many of these companies were forced to shut down or face bankruptcy because they could no longer compete without their old network of favors. The study explicitly rules out the idea that these failures were simply due to a general economic downturn or the pandemic; the pattern was specific to regions with higher anti-corruption activity and to firms that relied heavily on government procurement.
This shock did not stop at the factory gates; it traveled through the supply chain to affect what people bought and how they lived. The campaign drastically reduced the demand for goods associated with official entertainment, such as high-end liquor, luxury dining, and premium gifts. The researchers documented a sharp decline in the production of baijiu, a traditional Chinese liquor, which fell from 7.9 billion liters in 2019 to 4.2 billion liters in 2024. As demand for these items dried up, the orders for the factories that made them also dropped, causing a measurable slowdown in manufacturing activity across the country. This downward pressure on demand was a direct consequence of officials and businesses cutting back on the lavish spending that had previously fueled these sectors.
As factories struggled and cut jobs, the displaced workers did not simply vanish; they moved into the flexible, on-demand labor market. The study tracks this shift, noting that by 2024, flexible employment in China had reached 240 million people, with about 84 million working on digital platforms as delivery riders or ride-hailing drivers. The researchers found a clear link between the rise in anti-corruption enforcement and the growth of this gig economy. As formal manufacturing jobs disappeared in relationally dependent sectors, workers were pushed toward these alternative platforms to make a living, illustrating a massive reallocation of labor driven by institutional change.
Perhaps the most surprising finding concerns how competition changed in industries dominated by state-owned enterprises. When the anti-corruption campaign reset the rules for who could bid on contracts, it kicked out the old, connected suppliers. However, the new companies that entered the market did not bring better technology or higher quality. Instead, they were often similar to the companies they replaced, lacking the ability to differentiate themselves. This led to a phenomenon the researchers call "involution," where many similar companies crowded into the same market and competed solely on price, driving down profits for everyone without improving the industry. The study argues that simply removing corruption is not enough to create a better market; without support for new entrants to develop unique capabilities, the result can be a crowded, low-margin race to the bottom.
The researchers emphasize that these findings highlight a fundamental tension in institutional reform. While the anti-corruption drive is necessary to remove unfair advantages and improve the long-term health of the economy, it creates a fragile period of adjustment. During this time, supply chains break, demand contracts, and competition becomes unproductive. The study suggests that policymakers need to be aware of these short-term costs. To manage the transition, they recommend that governments provide support to help small manufacturers adapt, assist workers moving to new types of jobs, and ensure that new market entrants have the chance to develop real capabilities rather than just competing on price. The goal is to navigate the difficult journey from a system based on connections to one based on rules and quality, ensuring that the short-term pain does not derail the long-term promise of a fairer economy.
