China wants its middle class to spend big … but they have bills to pay
China’s middle class is something of a mythical entity, with wide-ranging estimates of its
size and economic power. Optimists believe a large and growing middle class has the
ability to lift China and even the world to a more prosperous level, while pessimists foresee
an increasingly burdened group that could cause the economy to stagnate and even lead
to political chaos.
Beijing wants the middle class to come to the rescue of China’s economy. But rising costs,
mounting household debt, worries about their future income as the economy slows and
doubts over whether the government can adequately provide for the ageing population
have made consumers cautious. In many cases, they are doing the opposite of what the
government wants and pulling back from spending. Whether this so-called consumption
downgrade is broad-based – and a threat to Beijing’s economic plans – or not is a matter
of intense debate in Chinese policymaking circles. But it is clear that many in China’s
middle class are struggling to make ends meet. …………
China is now betting that its middle class – the largest in the world with more than 400
million consumers, according to the authorities’ estimate – will increase their discretionary
spending on products and services and help stabilise the economy amid the trade war with
the United States. The National Development and Reform Commission, the government’s
powerful planning agency, last month announced that it had organised a special forum to
study increasing salaries for lower-middle, middle- and upper-middle income groups,
whose average annual individual disposable earnings range from 13,843 yuan to 34,547
yuan.

Explain, using the AD/AS framework and with the aid of a graph, how a trade war with the US
will impact on China’s GDP. Using the AD/AS graph now explain how the middle class can
come to the rescue of China’s economy. Using economic terms what are the reasons why the
middle class may not increase spending as hoped by the Chinese government? [hint: trade war
will increase prices of Chinese goods in the US] (4 marks). – Word count 350
