As can be seen from the chart, accounting for the largest share of that are the houses and buildings, machinery and equipment, motor vehicles, office equipment. Automotive industry compared to other industries rather special, is labor-intensive enterprises, fixed assets accounted for a large proportion in total assets, the need for greater production workshop and a large number of machinery and equipment in the production process also involves a large number of professional production and technical staff, the biggest fixed capital in fixed assets are detailed in machinery and equipment, mainly because of the importance of machinery and equipment in the new energy automobile production process. BYD recently added some new energy automotive-related production equipment and some car production lines, the BYD greater investment in machinery and equipment in the production process, scale production plant has been expanded industrial base is also expanding, which a series of initiatives, in order to constantly increase their production capacity, expand their scale of operation to meet the needs of users and the market, in order to achieve the strategic goal of BYD. These conditions will inevitably lead to a large proportion of funds invested in BYD's a lot of equipment, resulting in a large proportion of fixed assets BYD, 2015 - Fixed assets ratio of 2019 point of view, in recent years, BYD fixed capital in total assets reduced the proportion of each year. Data show that the mobile phone parts and assembly operations, BYD has decreased, sold their wholly-owned subsidiary in 2015: Shenzhen BYD Electronic Components Co., Ltd., there are other wholly owned subsidiary, in the new energy the automotive sector and related businesses to increase the strength, new energy is a technology-intensive business is asset-light business, mobile phone parts and assembly are labor-intensive mechanical type of asset-heavy business, precisely because BYD turned to light new energy business assets, so the proportion of fixed assets decreased year by year.
