The discussion of the contribution may be seen in the indicators of economic development, such as stimulating growth in the secondary industry.

For example, the construction of infrastructure projects like roads, bridges, and buildings can create jobs and boost economic activity in the secondary industry. This can lead to increased production, investment, and overall economic growth.

Additionally, the contribution of infrastructure development can be seen in the improvement of transportation and logistics networks, which can reduce costs for businesses and improve efficiency in the movement of goods and services. This can attract more investment and business activity to an area, further stimulating economic development.

Furthermore, infrastructure development can also have a positive impact on the quality of life for residents, by providing better access to essential services like healthcare, education, and clean water. This can lead to improved living standards and overall well-being, which can in turn contribute to economic development through increased productivity and consumer spending.

Overall, the contribution of infrastructure development to economic development is significant and multifaceted, with benefits that extend beyond just the construction sector. By investing in infrastructure, governments and businesses can create a foundation for sustainable economic growth and development.
