Abstract:In the era of digital economy, how to measure the digitization level of manufacturing enterprises? Absolutely, the construction of an index system for analyzing the digital level of manufacturing enterprises is particularly important in the tide of digital transformation of manufacturing enterprises. Based on the innovative value chain theory, this paper uses the factor analysis method to construct the analysis index system of the digitization level of manufacturing enterprises based on the data of 107 manufacturing enterprises in Guangdong Province, and further uses the FA-AHP combination weighting model to measure the digitization level of manufacturing enterprises in Guangdong Province and analyze the overall trend of development. The results show that, first, it is appropriate to describe the digital level of manufacturing enterprises from the four dimensions of digital benefit,the degree of investment in digital technology,the quality of labor and the management mode of production operation; second, the sample enterprises have different performance in the four dimensions, and there are no enterprises that perform well in all aspects. Third, there are regional differences in the overall level of digitization, digital benefits and digital investment, that is, the performance of the Pearl River Delta region is better than that of the non-Pearl River Delta region. This study provides a theoretical basis and reference value for measuring the digital level of manufacturing enterprises.
