More bits, fewer bricks
An interesting paradox of China’s success is its rapid growth despite an
underdeveloped financial system. An index of “financial repression”—based
on ownership of banks, regulation of interest rates, intervention in credit
allocation, and control of cross-border capital flows—shows China to be one
of the most repressed among major economies, similar to India. It ranks as
moderately more financially repressed than Russia and South Africa and
considerably less liberalized than advanced economies. Almost completely
controlled until the 1980s, the Chinese financial system made good progress
toward liberalization until about 2000, but has stalled ever since.
Our interpretation is that the initial steps in liberalization were
sufficient to carry out the straightforward task of channeling the
country’s high savings into export-oriented manufacturing and housing. A
moderate amount of financial repression can be helpful at this stage of
development to ensure that the cost of capital remains relatively low. In
both these sectors, lending depends on physical collateral (property,
buildings, machinery), so allocation is not that difficult. China’s exports
come largely from private firms, not state enterprises. Real estate
development and housing ownership are also private. So a policy that
encouraged exports and real estate was indirectly a policy that channeled
resources to the private sector.
The period between accession to the World Trade Organization, in 2001, and
the global financial crisis, in 2008, was the golden age of China’s growth.
There was rapid credit growth, but sufficient GDP growth to keep metrics
such as the ratio of nonfinancial corporate debt to GDP stable. This all
changed in 2008. To maintain demand in the wake of the global shock, China
invested massively in infrastructure by lending to local governments and
upstream sectors such as steel that tend to be state-dominated.
At the same time, the central government decided to channel more resources
into key state enterprises, hoping to help them become global champions.
The surge in lending to local governments and state enterprises caused
overall indebtedness in the economy to grow at an alarming rate, showing
that the financial system was not performing well in the new environment.
If the financed investments had produced strong growth effects, the
debt-to-GDP ratio would have remained stable or risen more slowly. A
rapidly rising leverage ratio is a sign that poor investments are being
financed.
In recent years, the weakness in capital allocation is also underscored by
the stalling of total factor productivity, which measures productivity
growth not explained by labor or capital increases. In the early 2000s,
following significant direct investment that helped build up the domestic
private manufacturing sector, total factor productivity grew 2.6 percent a
year, accelerating to an impressive 3.9 percent in the later part of the
past decade. Since the global financial crisis disruption, it has never
recovered, growing only 0.2 percent a year between 2015 and 2019.
Stagnant productivity is a signal that China needs more innovation, and a
diversified financial system to support it. China has many of the
ingredients that contribute to innovation—a large domestic market; high
spending (2.4 percent of GDP) on research and development; millions of
scientists, engineers, and software developers graduating every year; and
gradually improving intellectual property protection. Still, innovation
output is inconsistent. There are some impressive areas of technical
advancement, such as fintech and artificial intelligence, but productivity
growth for the economy as a whole is weak. The state still channels a lot
of resources to its own enterprises, whereas most patents are generated by
private firms.
The financial system does a better job of funding firms with traditional
assets (buildings, machinery) rather than dynamic start-ups built on
intellectual property. As China fine-tunes its next five-year plan, it
should focus on strengthening the innovation ecosystem, including its
financing, rather than supporting particular industries and technologies.
Innovation will be the key to meeting the country’s environmental goals,
especially the target of zero net carbon emissions by 2060.
