India's manufacturing sector has hovered between 15% and 17% of GDP since roughly 2005 — through three different flagship industrial policies, a currency crisis, a pandemic, and a decade of "Make in India" messaging. That flatness is the single most important fact in Indian industrial policy, and it's remarkably under-discussed relative to how often the target itself gets restated.
This essay is about why the number hasn't moved, using South Korea and Vietnam as the two clearest comparison cases of countries that pushed manufacturing share up by 8-10 percentage points within 15 years.
Four bottlenecks, ranked by evidence
Land acquisition cost and time remain the most-cited constraint in manufacturer surveys, but the data suggests logistics cost is the more binding constraint at the margin — India's logistics cost as a share of GDP sits meaningfully above China's and Vietnam's.[1]
Capital access for mid-sized manufacturers — the tier between large conglomerates and micro-enterprises — remains the least-served segment by both public sector banks and formal NBFC lending.
What actually moved the number elsewhere
South Korea's manufacturing share rise in the 1970s-80s was inseparable from export discipline: firms that didn't hit export targets lost access to subsidized credit within a fixed review cycle, not indefinitely.[2] That conditionality — protection in exchange for measurable performance, not permanent protection — is the mechanism most often missing from India's version of industrial policy.
