BEIJING, June 16 (Xinhua) -- China's economy sustained generally stable momentum in May, as solid fundamentals and strong resilience helped withstand external challenges, while growing new drivers continued to provide firm support for high-quality development, official data showed Tuesday.

China's value-added industrial output grew 4.5 percent year on year in May, 0.4 percentage points faster than the growth in April. On a month-on-month basis, the volume rose 0.4 percent from April, according to data released by the National Bureau of Statistics (NBS).

By sector, equipment manufacturing and high-tech manufacturing posted faster growth, underscoring the strengthening role of new drivers.

The value-added output of equipment manufacturing rose 9.5 percent year on year in May, while that of high-tech manufacturing surged 15.1 percent, accelerating by 1.2 and 2.3 percentage points from the previous month, respectively.

Output of 3D printing equipment, lithium-ion batteries, and industrial robots jumped 54.4 percent, 40 percent, and 27.9 percent, respectively.

Despite a complex and volatile international environment, the continuing spillover effects of geopolitical conflicts in the Middle East, and the impact of high temperatures and heavy rainfall in some regions, China's economy continued to show a generally stable trend with improving structure and quality, noted NBS spokesperson Fu Linghui at a press conference.

While Tuesday's data showed that China's fixed-asset investment remained under pressure due to weakness in the property sector, investment in innovation-related areas continued to expand, reflecting the ongoing transition from old growth drivers to new ones and the shift in investment from aggregate expansion toward quality improvement.

In the first five months, fixed-asset investment excluding rural households totaled 17.85 trillion yuan (about 2.62 trillion U.S. dollars), down 4.1 percent year on year. Excluding real estate development, fixed-asset investment declined 1.2 percent.

By contrast, investment in intellectual property products grew 9.3 percent year on year, 0.4 percentage points faster than in the January-April period. High-tech industry investment rose 4.5 percent, with investment in computer and office equipment manufacturing, aerospace equipment manufacturing, and information services up 18.3 percent, 16.7 percent and 13.8 percent, respectively.

Despite the overall slowdown, continued policy support, stronger innovation-led development, and greater efforts to safeguard people's well-being have helped further improve the investment structure, according to Fu.

On the closely watched consumption market, China's total retail sales of goods and services increased by 2.8 percent year on year in the first five months.

Service consumption maintained solid growth, with retail sales of services rising 5.4 percent year on year, continuing to outpace retail sales of goods.

New forms of consumption continued to expand. Online retail sales of goods and services grew 5.9 percent in the first five months, faster than overall goods retail sales. Digital and green consumption also gained momentum, with retail sales of communication and information services rising by more than 10 percent and sales of high-efficiency home appliances by over 30 percent.

Still, residents' capacity and willingness to consume need to be further strengthened, and market supply in some areas has yet to fully meet the needs of consumption upgrading, Fu said, pledging more efforts to boost consumption, raise incomes, create new consumption scenarios and improve the consumption environment.

The set of economic data came as, since the second quarter, some economic indicators in China have slowed, and some enterprises have faced operational difficulties due to a more complex international environment and domestic structural adjustment pressures.

However, Fu stressed that the broader trend of China's economy remaining generally stable and making steady progress has not changed, and the shift toward new growth drivers and an improved structure remains clear.

"Going forward, the growth of new quality productive forces, the continued release of reform and opening-up dividends, and the impact of stronger macro policies will continue to support stable economic performance and further improvement in structure and quality," Fu said.
