How do Tamil Nadu and Karnataka differ in their manufacturing models?

Tamil Nadu and Karnataka exhibit two distinct state-level industrial models for attracting global investments and manufacturing under "China+1" supply chain diversification strategies:

1. Historical Foundations and Core Ecosystems

• Tamil Nadu: Developed its industrial base over four to five decades by investing in technical education and building an extensive automobile and auto-components ecosystem around Chennai. This long-term effort created mature supplier networks, skilled labor, and administrative expertise.

2. Sectoral Focus and Industrial Clusters

• Tamil Nadu: Built major assembly hubs at Sriperumbudur and Hosur, securing investments from major global suppliers like Foxconn and Tata Electronics. As the state encounters limits in land, power, and local labor (relying significantly on migrant workers), it is actively pivoting from labor-intensive assembly toward capital-intensive manufacturing and innovation-led exports.

3. FDI Equity Inflow Ranking

• According to DPIIT FDI equity inflow data (October 2019 to March 2026), Karnataka ranks second in India with 21% of total inflows, whereas Tamil Nadu ranks fifth with 6%. However, this metric reflects where companies register their corporate head offices rather than where physical factory floors are constructed.

4. Shared Supply Chain Bottlenecks

• Despite their individual strengths, both states face the broader national challenge of thin backward linkages. Local value addition in assembled electronics remains around 20%, leaving a substantial reliance on imported major parts and supply chains.
