The output value of the five pillar industries in Haimen district, Nantong, East China's Jiangsu province, hit 64.09 billion yuan ($8.88 billion) in the first half of this year, up 22 percent year-on-year, according to authorities.

The five industries are high-end equipment manufacturing, new materials, biomedicine, new energy, and new-generation information technology, constituting an important part of Haimen's modern industrial system.

One of the main reasons behind the high-quality development of the district's manufacturing industry is that authorities have been making efforts to nurture little giants, referring to small and medium-sized enterprises specializing in niche sectors, commanding a high market share, and boasting a strong innovative capacity and core technologies.

Nine companies based in the district were shortlisted as national little giants this year.

Another major factor behind Haimen's industrial economy is authorities' efforts to optimize the business environment.

In addition to releasing an action plan and unveiling 70 measures, authorities held summer camping activities from July 10 to Aug 18 for the children of migrant workers.

Huang Weiguo, Party secretary of Haimen Port New Area, said that holding such activities can alleviate the burden on parents and allow them to focus more on work.
