Purpose This paper aims to examine the influence of information technology (IT) investment, including innovative IT investment and non-innovative IT investment, on comprehensive enterprise financial performance in a developing country, China. Design/methodology/approach This paper applies the method proposed by Barber and Lyon to construct the control group to study the impact of IT investment on financial performance of enterprises, using a sample of 229 IT investment announcement data of Chinese listed companies between 2011 and 2015. Findings The analysis of the financial benefits of these IT implementations yields mixed results. The results show that companies investing in IT can significantly improve profitability both the implementation and post-implementation periods for the full sample, improve the solvency only during the implementation phase, improve the growth ability after implementation time and cannot reduce business costs in all periods. At the same time, the authors find that, compared with non-innovative IT investment, the innovative samples do not achieve better financial performance, except the profitability financial indicator. Research limitations/implications There are several limitations in this research. First, there is no large sample about the IT investment information data set in China, so this study was compelled to use limited sample data from China; hence, this could lead to errors of too early generalization. Second, the firms in the sample are all in China’s listed companies, so this may either not accurately or possibly could reflect the entire environment of developing countries. Originality/value First, it extends the scope of the established literature by examining the influence of IT investment with China’s public firms data and IT investment to see if such spending has had an influence on corporate financial performance. Second, there is a lack of research on the impact of IT investment on comprehensive financial performance of an enterprise, compared with the previous one-sided financial performance, such as profitability or financial cost. Third, as far as the authors are aware, there are no studies on the impact of IT investment on firm financial performance based on innovative and non-innovative classification.

Purpose The purpose of this study is to deepen the understanding of the effects of information technology (IT) investment on firm innovation performance and examining the investment paradox effect in China. Design/methodology/approach Using a sample of China’ public firms IT investment data between 2010 and 2016, the authors establish a test model of IT investment and innovation performance. Findings The result indicates that IT investment in firms have no effect on innovation performance in the investment period. However, in the full sample and manufacturing sample, the IT investment has a significant positive effect on innovation performance in the post-investment years. In addition, this study finds that large companies and low-age companies may contribute more to innovation when firm investment in IT. Research limitations/implications There are several limitations in this research. First, the authors are failed to obtain a larger sample about the IT investment information data set in China, so this study was compelled to use limited sample data from China, hence, this could lead to errors of too early generalization. Second, the authors use the number of invention patent applications to represent the performance of enterprise innovation, which may not show enterprise innovation effectively. Third, the firms in the sample are all in China Listed Companies, so this may not accurately reflect the entire environment of firm innovation performance, and could possibly. Practical implications The research confirms that there is a paradox and time lag effect in IT investment, which enterprises should pay attention to. Originality/value Existing research confirms that corporate IT investments can bring new products or services. However, the authors still do not know whether IT investment has improved the company’s ability of innovation. This study will fill this gap and the industry effect and time lag effect of the influence of IT investment on innovative performance are also examined.
