Economic Geography: Understanding the Spatial Distribution of Economic Activities
Economic geography is a subfield of human geography concerned with the locational, organizational, and distributional patterns of economic activities in space. It seeks to understand why economic activities are located where they are, how they interact with each other, and how these patterns influence human societies and the environment. For competitive exams like the UPSC Mains, a strong grasp of economic geography is crucial for analyzing socio-economic issues, understanding development patterns, and framing policy-relevant arguments.
Key Concepts in Economic Geography
Several core concepts underpin the study of economic geography. These include:
Sectors of Economic Activity and Their Spatial Distribution
Economic activities are broadly classified into primary, secondary, tertiary, and quaternary sectors, each with distinct spatial patterns.
| Sector | Key Activities | Spatial Distribution Factors |
|---|---|---|
| Primary | Agriculture, Mining, Forestry, Fishing | Proximity to natural resources, climate, topography, soil fertility, water availability |
| Secondary | Manufacturing, Construction, Energy Production | Access to raw materials, labor availability, transportation networks, energy sources, market proximity, government incentives |
| Tertiary | Services (Retail, Healthcare, Education, Finance, Tourism) | Population density, income levels, consumer demand, accessibility, infrastructure, specialization |
| Quaternary | Information services, R&D, IT, consulting | Skilled labor availability, access to information networks, research institutions, quality of life, agglomeration economies |
Economic Geography and Development
Economic geography plays a vital role in understanding regional development disparities, the impact of globalization on developing economies, and the spatial implications of economic policies. It helps analyze why some regions prosper while others lag behind, and how factors like infrastructure, resource endowment, and policy interventions shape economic outcomes.
Understanding the spatial distribution of economic activities is key to analyzing global inequalities and formulating effective development strategies.
Key Theories and Models
Several theories and models are central to economic geography. These provide frameworks for analyzing spatial economic phenomena.
The concept of spatial interaction is fundamental to economic geography. It refers to the movement of people, goods, capital, and information between different places. The strength of spatial interaction is influenced by distance (often measured by friction of distance, where increasing distance reduces interaction) and connectivity (the ease with which interaction can occur, facilitated by transportation and communication networks). Models like Gravity Model predict interaction between two places based on their mass (population or economic size) and the distance between them. For example, a larger city will have more interaction with another large city than with a small town, especially if they are close.

Contemporary Issues in Economic Geography
Modern economic geography grapples with issues such as:
- Regional disparities: Understanding the causes and consequences of uneven development between regions.
- Sustainable development: Analyzing the spatial impacts of economic activities on the environment and exploring sustainable economic models.
- Urbanization and megacities: Studying the economic functions and challenges of large urban agglomerations.
- Digital economy and remote work: Examining how technology is reshaping the geography of work and economic activity.
- Geopolitics of resources: Understanding the spatial distribution of critical resources and their impact on international relations.
Connectivity (ease of interaction via transportation and communication networks).
Preparing for Exams
To excel in competitive exams, focus on understanding the interrelationships between economic activities, their spatial patterns, and their socio-economic and environmental consequences. Use case studies of different regions and countries to illustrate theoretical concepts. Practice drawing diagrams and maps to visually represent economic phenomena.
