However, the effect of loT on economic growth has not been fully explored. This paper analyzes this issue from the perspective of ICT investment. After analyzing the data of eight representative provinces from 1996 to 2008, we f＇md out that the effect of ICT investment on e- conomic growth is limited and the levels of telecom- munications infrastructure and education are key factors influencing the effect. Thus it＇s necessary to further improve the telecommunications infrastructure and enhance related education and training to promote the effect of loT on economic growth.展开更多

Therefore, it is very necessary to continuously carry out experiment teaching reform, improve experiment teaching methods and means, and comprehensively open laboratories so as to provide students with more opportunities of doing experiments. To improve the teaching effect of electronic information experimental courses, a network interactive virtual experimental platform is developed. This platform allows students to finish the construction of all kinds of circuit structures and test virtual instruments in a simulation environment, upload experimental data and also interactively communicate with teachers through the lnternet. The platform can be applied to the teaching activities of related electronic information experimental courses, and also can be used as an aid teaching method for theory teachers. Therefore, it possesses a very good interactivity, and makes up the disadvantages of the experimental teaching in hardware environment, so that a feasible solution is provided for the opening of laboratories.展开更多
