As Chinese authorities struggle to contain runaway home prices, a long-awaited plan for a property tax has stalled, the latest sign of entrenched interests impeding efforts to transform the country’s growth model. 

The average price of a Shenzhen home last year was 41 times the average income, against 29 in London, 23 in Tokyo and 15 in New York, according to Macquarie Securities. Since late last year, 45 Chinese cities have introduced purchase limits and other measures in a bid to cool rising property prices. 

For years, economists have advocated for China to move away from administrative tools like purchase bans in favour of a property tax. Top Communist party leaders committed to imposing a property tax in a landmark blueprint for economic reform approved in November 2013.
