Under the background of big data, the transformation of internal control in enterprise financial management is not only the inevitable requirement of information development, but also the basic requirement of the development of enterprise management accounting. Based on this, the basic ability of internal control personnel in enterprise financial management should be strengthened, and forward-looking financial management and control thinking should be constructed in order to promote the transformation and development of enterprise financial management under the background of big data.展开更多

The theory of "Internet +" highlights new turn in the strategic transformation of liquor-making industry. This paper, under the background of "Internet +", analyzes the existing situations of liquor-making industry, provides transition routes of strategic transformation in liquor-making industry, and gives prevention against transformation risks.展开更多
