A negative net increase in cash and cash equivalents typically indicates that the cash outflow of a company is greater than its cash inflow. This means that the company has experienced a cash shortage during this period and needs to raise funds to support its operations. This may be due to the company facing operational difficulties, expanding investment, or repaying debt, among other reasons.

Specifically, if the net increase in cash and cash equivalents is negative, the company may need to increase cash inflow through fundraising activities, such as obtaining a bank loan, issuing bonds, or raising funds through stock issuance. In addition, the company can also take measures to reduce cash outflows, such as reducing costs, optimizing supply chain management, and cutting expenses.

Overall, a negative net increase in cash and cash equivalents indicates that the company's cash flow status is relatively tight, and corresponding measures need to be taken to improve the cash flow situation to support the sustainable development of the company.
