# The 50 largest companies with in-house R&D in Shandong

Tamtam tracks 51 companies with in-house R&D headquartered in Shandong. This list ranks the 50 largest by number of employees on LinkedIn, led by Haier, GoerTek Inc. and Hisense Group. Their median headcount is 416. Half of them were founded in 1999 or later.

These Shandong-based companies are mostly large firms in manufacturing, with a focus on electronics, chemicals, and industrial equipment. Notable examples include Haier, a global provider of IoT solutions, and Hisense Group, which manufactures consumer electronics and home appliances. Wanhua Chemical Group is a leader in polyurethanes manufacturing, while KERUI PETROLEUM specializes in petroleum equipment and oilfield services. Shandong University stands out as a major higher education institution. Another key player is GoerTek Inc., a global leader in component parts and finished products. These companies collectively demonstrate a strong regional concentration in manufacturing.

The data shows a significant cluster of companies with headquarters in Qingdao, including Haier, Hisense Group, and CIMC Qingdao, which manufactures reefer containers. Weifang also features prominently with companies like GoerTek Inc. and Rainbow Agro. The presence of both established giants and younger firms, such as Wanhua Chemical Group (founded in 1998) and Mesnac Co., Ltd (founded in 2000), indicates a mix of long-standing industrial strength and more recent technological development.

## How this list is built

Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 12, 2026.
