Since the Outline of the Development Plan for the Guangdong-Hong Kong-Macao Greater Bay Area was issued and implemented in February 2019, Shenzhen has promoted high-quality development of the Greater Bay Area, accelerated reform and innovation, and promoted integrated development. With new measures to further integrate rules and ensure total circulation of market factors, remarkable results have been achieved in regional collaborative innovation.

Over the past three years, cities in the Greater Bay Area have strengthened their connectivity and explored new mechanisms and paths for integrated regional development. Shenzhen's GDP has reached 3 trillion yuan ($447.3 billion), with more than 20,000 national high-tech enterprises, and its Qianhai district has launched 685 institutional innovations.

A sound business environment is a fundamental guarantee for coordinated and high-quality development of the Greater Bay Area. According to statistics from Shenzhen Customs, since the beginning of this year, the import and export throughput of the "Greater Bay Area combined ports" project has exceeded 100,000 twenty-foot equivalent units, up 5.2 times year-on-year. 

By 2025, according to the plan of the Shenzhen municipal government, the added value of its strategic emerging industries will exceed 1.5 trillion yuan, and the strategic emerging industries should become the main engine for the city's high-quality economic and social development.

Notably, Luohu, the first district founded in Shenzhen, proposed three action plans to give full play to its geographical advantages as a neighbor of Hong Kong and focus on complying with international rules on investment, trade, etc., to build new platforms and institutions for an open economy.
