This paper highlights some of those significant advances in the informationization of accounting information systems in China. As China has become a major industrial power in the international economy, further improvements for these information systems are critical to the continued successes of China. To additionally improve these systems, China can draw upon the systems from other world economic leaders. With its fully developed capital markets, the United States offers development experience for the external reporting components of a fully integrated information system. This paper discusses a typical integrated information system in the United States and addresses the regulatory milestones that were instrumental in the development of those external components of accounting information systems. Recommendations are presented for improving informationization of systems in China based on U.S. systems＇ responses to those milestones.展开更多

Using the statistical data of the gross agricultural output value of Hubei Province in 2005-2014,based on the C-D production function,it calculated the average contribution rate(2. 48%) of agricultural informationization to the growth of agricultural economy in Hubei Province,indicating that agricultural informationization can promote growth of agricultural economy. This is basically consistent with previous findings. In addition,investment in agricultural informationization and broadband access rate also influenced the growth of agricultural economy in Hubei Province. Therefore,government should further improve the infrastructure of agricultural informationization,strengthen training of farmers’ information skills,establish auxiliary mechanism for achievement feedback of information-based agricultural production,increase the contribution rate of informationization to agricultural operation and management,promote the contribution of informationization to the growth of agricultural economy,so as to increase agricultural income of farmers.展开更多
