The Chinese economy's comparative advantage largely comes from research and innovation, said Wu Yibing, head of China for Singapore's state investment company Temasek. In the past, China's strength in manufacturing was usually attributed to its abundant labor force and high production efficiency, said Wu.

In the first half of the year, the country's value-added industrial output, an important economic indicator, increased by 6 percent year on year, according to the NBS data.

The high-tech manufacturing industry also posted strong growth, with its output up 8.7 percent in the first half, according to the NBS.

The country's production of service robots, smartphones and new energy vehicles surged 22.8 percent, 11.8 percent and 34.3 percent, respectively, in the first six months.

Bloomberg said in a report on July 16 that China's long-term quest for high-quality growth is starting to bear fruit.

"Advances in electric vehicles, solar panels and other high-tech industries have helped keep economic expansion within reach of its targeted pace of around 5 percent," said the report.

Apart from industrial output and high-end manufacturing, investment and exports are also seen as the highlights of China's economy by the institutions.

The effects of large-scale equipment upgrades and trade-in of consumer goods continue to manifest, driving effective investment along with the issuance of local government special bonds and ultra-long special treasury bonds, said Ji Mo, chief China economist of DBS Group Research.

Data shows that China's investment in infrastructure construction during the January-June period rose 5.4 percent from the previous year, while manufacturing investment increased 9.5 percent.

The country's net exports of goods and services drove GDP growth by 0.7 percentage points in the same period.

China has become increasingly important as a major global supplier of goods and has continued to expand its market share despite trade restriction measures, said Liu Jing, chief economist for Greater China at HSBC.

The accelerated development of new quality productive forces, the continuous release of policy effects and the recovery of external demand have supported China's economy, but further reform and opening-up is needed in the face of challenges such as insufficient effective demand and a complex external environment, multiple experts from the overseas financial institutions have said.
