Due to the limitations of research methods, financial management theory also has certain limitations in research scope. For example, the capital budgeting process is a very important issue for corporate management practice, but the current financial management theory mainly focuses on the field of investment project evaluation, and rarely studies the overall process and other important links, which may be more important for making good investment decisions; for example, financial management theory is based on the assumption of the effectiveness of the capital market, and cyprus lists often excludes many very important factors in strategic management as irrelevant variables from the research scope; and, because financial management theory has developed to the "rigorous quantification" stage, it does not pay enough attention to the research of many difficult to quantify or non-quantitative factors, which are likely to play a decisive role in strategic management. The limitations of the research scope make the current financial management theory and methods lack relevance to corporate strategy, and thus cannot fully meet the requirements of strategic management .
