Impact of Macao exhibition Industry Influence on Economic Development in the Belt and Road Mode

摘要

In order to study the driving effect of Macao exhibition on economic development, economic forecast algorithm of Macao exhibition, two-way restricted deep DDRBM-DNNS algorithm based on sparse cross entropy is presented. Firstly, sparse cross entropy penalty parameter and bidirectional structure are used to improve the traditional DDRBM-DNNS algorithm, so as to effectively increase the predictive performance of the algorithm; secondly, the designed sparse cross entropy DDRBM-DNNS algorithm is used to construct forecast model of Macao exhibition’ impact on the economy. At the same time, the 1970~2013 exhibitions and economic data are selected to carry out experimental verification. Simulation results show that sparse cross entropy DDRBM-DNNS algorithm is better than the selected contrast algorithm in prediction accuracy. At the same time, the prediction accuracy decreases with the increase of the distance between the city and Macao, which reflects the radiation and driving effect of Macao exhibition on the economy to a certain extent.
