Since the beginning of spring 2025, a wave of cooperation led by new quality productivity has surged in Xiangjiang. From intelligent manufacturing to biomedicine, from green energy to digital economy, multiple provinces in mainland China have intensively visited Hong Kong for promotion and exchange, and cooperation has moved towards broader fields, deeper levels, and higher levels. Compared with previous years, this year's promotional activities have presented more "science and technology empowerment" features. In March, at the "Heilongjiang Hong Kong Investment Cooperation Exchange Conference" hosted by the Department of Commerce of Heilongjiang Province, the robot arm of the Advanced Technology Research Institute of Harbin Institute of Technology flexibly grasped objects, and AI digital humans used humorous language to attract audiences to interact; In May, the Hunan Hong Kong Investment and Financing Matchmaking Fair released the "Demand Project Information Handbook" covering 203 projects, with over 60% coming from high-tech enterprises... These changes reflect the transformation of cooperation between the mainland and Hong Kong from traditional agricultural product trade and investment attraction to technological innovation and industrial cooperation. Tan Yueheng, a member of the National Committee of the Chinese People's Political Consultative Conference and a member of the Legislative Council of the Hong Kong Special Administrative Region, said in an interview that Hong Kong and the mainland are building a collaborative model of "research before production", and Hong Kong's basic scientific research advantages are perfectly complementary to the manufacturing capabilities of the mainland. He said that as the level of cooperation deepens, the promotion and entry of enterprises from mainland China to Hong Kong will inevitably show a trend of "specialization, refinement, uniqueness, and novelty", and the scope of cooperation will also expand from traditional investment and financing to multiple fields such as industry, academia, and research. The government's joint promotion has become a prominent feature of this year's promotional activities. Several provincial party secretaries and governors led delegations to Hong Kong to have in-depth communication with the SAR government. Li Jigang, Director of the Department of Commerce of Heilongjiang Province, stated that this year's exchange meeting is the largest and highest standard overseas economic and trade event held by Heilongjiang Province in recent years, and also marks a new level of economic and trade cooperation between Longgang and other cities. The cooperation model is also continuously innovating. Hunan Province has released an information booklet on investment and financing demand projects, which systematically displays the province's scientific and technological innovation needs; Establishing a long-term cooperation mechanism between Shandong Province and the Hong Kong Trade Development Council; Jilin Province leverages the Hong Kong platform to promote the internationalization of Changbai Mountain's characteristic industries; Yunnan and Hong Kong investors have reached practical cooperation in deepening green energy, new materials, plateau characteristic agriculture, biomedicine, cultural tourism and health care. Fan Minhua, vice president of the Chinese General Chamber of Commerce in Hong Kong, said that Hong Kong was upgrading from a "super contact" to a "super value-added person" to provide all-round support for mainland enterprises in brand building, international marketing, etc. New cooperation brings new space. The equipment manufacturing of the old industrial base in Northeast China, technological innovation in central provinces, and characteristic industries in the western region are all seeking new opportunities for development through the international platform of Hong Kong. Hong Kong Chief Executive Carrie Lam has repeatedly emphasized during meetings with provincial delegations that the SAR government attaches great importance to integrating into the overall development of the country and will fully leverage the advantages of "one country, two systems" to assist mainland provinces and cities in integrating into the global market. With the continuous expansion of cooperation depth and breadth, a new cooperation pattern is taking shape, with new quality productivity as the link and high-quality development as the goal. In this "two-way rush" across mountains and seas, Hong Kong's internationalization and specialization advantages, along with mainland China's industrial and innovation advantages, are jointly composing a new chapter of China's high-level opening-up to the outside world.
