Can technology-driven supply-side measures resolve deep domestic demand imbalances?
Core argument: Japan's consumption share of GDP bottomed at 63.3% in 1991 and took seventeen years to rise 10 percentage points to 73.8% by 2008, still below the global average, while China's stood at 53.4% in 2022.
The consumption share of Japan’s GDP bottomed out at 63.3% in 1991 (compared to 53.4% for China in 2022), and it took seventeen years for the consumption share to rise by 10 percentage points. In 2008, it had reached 73.8% (still below the global average). During that time, Japan’s share of global GDP dropped from 15% to 7.9%. I am not arguing that an intense supply-side focus on developing new technology won’t make a difference for China and will fail. It is certainly possible that such a focus could help China avoid—or at least reduce—a long and difficult adjustment associated with boosting a very weak demand side of the economy. But it is foolish to suggest that such a focus must inevitably work, and even more foolish to claim that China is the first country to try this approach. Many countries have tried to resolve demand imbalances with technology-driven supply-side measures—most notoriously the Soviet Union in the 1960s and Japan in the late 1980s and early 1990s—but it has always proved far more difficult than expected.
