Why did road construction have a major effect on remote parts of Yunnan?

Road construction has been transformative for remote regions of Yunnan, primarily by replacing the traditional, inefficient reliance on pack animals or human labor for transporting goods.1

The expansion of the highway network has provided several key benefits to these isolated areas:

• Modernization: Truck transport now reaches the majority of villages, facilitating the delivery of essential modern tools, fertilizers, and daily necessities to farmers.1
• Economic Growth: Improved connectivity allows farmers to ship their products to both local and distant markets, enabling them to sell their goods at the most advantageous prices.1
• Developmental Momentum: The road-development program has served as a vital catalyst for modernization in regions inhabited by minority peoples, effectively integrating them into the broader provincial economy.1

While some of the most isolated areas still rely on older methods of transport, the shift toward a comprehensive road network has fundamentally altered the economic landscape of the province's remote interior.1
