Final answer:
Physical infrastructure involves tangible assets such as roads and bridges, while social infrastructure comprises institutions like schools and hospitals. Physical infrastructure is a component of physical capital essential for economic activities, while social infrastructure enhances human capital and labor productivity.
Step-by-step explanation:
The difference between physical infrastructure and social infrastructure of development is akin to comparing tangible assets to intangible services that support the functioning and quality of life in a society. Physical infrastructure includes the basic physical structures required for a society to operate, such as roads, bridges, traffic signals, and utilities. These are critical components of physical capital that facilitate economic activities by enabling the transportation of goods and services, communication, and other forms of exchange.
In contrast, social infrastructure encompasses the institutions that contribute to the establishment of a healthy, educated, and well-functioning population. These institutions provide services like education, healthcare, and social services, which are crucial for enhancing human capital. Investment in social infrastructure is vital for improving labor productivity by ensuring workers are healthy, skilled, and knowledgeable.
