Synergistic policy on pilot free trade zone and national e-commerce demonstration city to promote urban-rural industry integration: Evidence from China

In the modern world, the gap between bustling cities and quiet countryside is often measured in income, but it is also measured in how industries connect. For decades, economists and planners have sought ways to weave these two worlds together, creating a system where city factories and rural farms work in tandem rather than in isolation. Two powerful tools have emerged to help bridge this divide. The first is a special economic zone, a designated area where rules are relaxed to encourage trade and business innovation, acting as a laboratory for new ways of doing commerce. The second is a digital initiative that designates specific cities as hubs for online shopping, using the internet to bring goods and services directly to people's doorsteps, regardless of where they live. While each tool has shown promise on its own, a lingering question remains: what happens when a city uses both at the same time? Does the combination create a simple sum of benefits, or does it spark a unique, more powerful force that reshapes how urban and rural economies interact?

A team of researchers set out to answer this question by looking at the real-world experience of cities across China. They focused on a specific period from 2008 to 2023, examining data from 285 cities to see how the simultaneous presence of a special trade zone and a national e-commerce demonstration city influenced the integration of urban and rural industries. The researchers treated this overlap as a natural experiment. They compared cities that received both designations against those that received only one or neither, carefully accounting for other factors like local wealth, education levels, and government spending to ensure a fair comparison. Their goal was to determine if the combination of these two policies acted as a catalyst, accelerating the flow of money, goods, and ideas between the city and the country more effectively than either policy could alone.

The study found that the answer is a clear yes. When a city held both the special trade zone status and the e-commerce designation, the integration of its urban and rural industries improved significantly. This was not merely a case of two policies adding their effects together; the combination produced a synergistic result, meaning the whole was greater than the sum of its parts. The researchers observed that cities with both designations saw a marked rise in the connection between city-based manufacturing and rural production. This happened because the trade zones opened up new institutional pathways, making it easier to move goods and capital across borders, while the e-commerce hubs built the digital roads necessary to move products quickly and efficiently to consumers. Together, they created an environment where businesses could thrive in both settings, linking the supply chains of the city with the resources of the countryside.

To understand how this magic of combination actually worked, the researchers traced the specific pathways the policies took. They discovered three main engines driving the change. First, the dual policy sparked a surge in urban entrepreneurship. The relaxed rules and digital tools encouraged more people to start new businesses, and these new ventures often reached out to rural areas for resources or markets. Second, it directly boosted rural e-commerce. The digital infrastructure supported by the e-commerce cities allowed farmers and rural producers to sell their goods directly to urban consumers, bypassing traditional middlemen and capturing more value for themselves. Third, the combination accelerated digital transformation across the board. Businesses in both cities and towns adopted new technologies to manage their operations, making the entire system more efficient and responsive. These three factors—more new businesses, stronger rural online sales, and faster digital adoption—worked together to pull the urban and rural economies closer.

The impact, however, was not felt equally everywhere. The researchers found that the policy combination worked best in specific types of regions. The effect was most pronounced in the western part of the country, as well as in inland areas and border regions. In these places, where the economic foundation was often weaker or more isolated, the dual policy provided a crucial lift. It helped overcome the barriers that usually keep these areas behind, using the trade zones to open new markets and the e-commerce hubs to connect them to the digital economy. Similarly, the policy was particularly effective in regions that balanced grain production with grain sales. These areas, which have a strong mix of farming and trading, were able to use the policies to streamline their entire supply chain, from the field to the final customer. In contrast, the effect was less dramatic in already wealthy coastal cities, where the economic systems were already quite integrated.

The study also took great care to ensure these results were not a fluke or the result of some other hidden factor. The researchers ran numerous tests, checking if the results held up when they changed the way they measured the data, excluded major cities that might skew the numbers, or accounted for other government programs launched at the same time. In every case, the positive link between the dual policy and industrial integration remained strong. They even compared cities with both policies against those with just one, confirming that the combined approach consistently outperformed the single-policy approach. This suggests that the specific mix of institutional openness and digital empowerment is a powerful recipe for development, one that is especially valuable for regions trying to catch up.

Ultimately, this research offers a clear lesson for policymakers and anyone interested in regional development. It shows that while individual initiatives like trade zones or digital hubs are valuable, their true potential is unlocked when they are coordinated. By aligning the rules that govern trade with the tools that enable digital commerce, governments can create a supportive ecosystem where urban and rural industries do not just coexist, but actively reinforce one another. The findings suggest that the future of balanced regional growth lies not in choosing between different strategies, but in weaving them together to create a more connected and resilient economy.
