Developmental state

A developmental state treats rapid industrial growth as its overriding goal and uses a capable bureaucracy to guide private firms towards it. Chalmers Johnson coined the term in MITI and the Japanese Miracle (1982), contrasting the "plan-rational" Japanese state with the "market-rational" American regulatory state. The state does not own most firms; it shapes their incentives.

• A meritocratic elite bureaucracy with a pilot agency (Japan's MITI, Korea's Economic Planning Board, Taiwan's Council for Economic Planning and Development).
• Control of finance: state banks or state-directed credit at preferential rates.
• Selective protection and subsidies for targeted industries.
• Reciprocity: support conditioned on performance, especially export targets (Amsden).
• Close but disciplined ties to business: "embedded autonomy" (Evans).
• Political insulation of economic policy from distributive pressure, often by suppressing labour.

Alice Amsden (1989) argued that South Korea industrialised by "getting relative prices wrong" deliberately and disciplining the conglomerates (chaebol) that received subsidies. Robert Wade (1990) described Taiwan's state as "governing the market". Peter Evans (1995) argued that successful states combine Weberian bureaucratic coherence with dense ties to business, avoiding both predatory states and captured ones. Stephan Haggard (2018) reviews the debate and stresses political foundations, such as external threats and the need for elite coalitions to deliver growth.

• Japan from the 1950s to the 1970s, under the dominant Liberal Democratic Party in a democracy.
• South Korea under Park Chung-hee (1961–1979), a military-led authoritarian regime that repressed labour and dissent.
• Taiwan under the Kuomintang party-state and martial law (1949–1987).
• Later cases are debated: Singapore, China, Vietnam, Ethiopia and Rwanda are often described with the term.

Neoclassical critics, and the World Bank's East Asian Miracle report (1993), argued that sound macroeconomics, education and export orientation explain most of the growth and that industrial targeting added little. Others note survivorship bias: many states tried industrial policy and failed. A further critique concerns rights: in Korea and Taiwan, developmental policy coexisted with martial law, torture and the suppression of independent unions.

The claim that authoritarianism caused the growth is a disputed hypothesis. Japan's developmental state was democratic; Korea and Taiwan democratised in the late 1980s and kept growing. Przeworski and Limongi (1993) found that statistical studies do not show a clear effect of regime type on growth, while Acemoglu, Naidu, Restrepo and Robinson (2019) estimate that democratisation raises GDP per capita in the long run.

Japan, South Korea and Taiwan moved from poverty or war damage to high incomes within two generations. How much of this the developmental state's mechanisms explain, and whether they can be copied where bureaucracies are weaker, remains disputed.
