Runaway growth in the mainland has rung alarm bells on the national statistics agency's economic warning index, with industrial production already showing signs of overheating.
The National Bureau of Statistics' warning came just days after the ruling Politburo urged that the country's foremost economic policy priority must be to prevent overheating.
The macroeconomic warning index rose to 114.7 in June, up from 113.3 in May and 110.7 in April, suggesting the economy was heading for a 'relatively heated' area, the agency said.
Of the 10 indicators the agency includes in the index, industrial production is now in the area of 'overheating'.
The indicators of fiscal revenue and urban residential income were 'relatively heated' while those for fixed-asset investment, retail sales, import and export, industrial profits, lending, broader money supply M2 and consumer price index were still in the 'stable' area.
The index has five grades - 'cool', 'relatively cool', 'stable', 'relatively heated' and 'overheating'.
The economy grew 11.9 per cent in the second quarter, an 11-year high, taking first-half growth to 11.5 per cent. Inflation rose to a 33-month high of 4.4 per cent in June, the bureau said last month.
