This paper starts from the industrial structure and characteristics of the Internet of Things and compares and analyzes the development ideas of the Internet of Things industry in the market economy under different systems. We also discuss IoT business model innovations and analyze the inadequacies of current IoT business models. We use the cost-benefit analysis method to analyze, from the aspects of social benefits, economic benefits, environmental benefits, and externalities. In this paper, factor analysis and quantitative statistics are used to calculate the weight of influencing factors, and the multilevel fuzzy evaluation method is used to score the influencing factor indicators to calculate the final score result, so as to judge the applicability of the multilevel fuzzy evaluation method to judge the profit model. In order to verify whether the establishment of economic regions plays a positive role in regional economic development, a double-difference model is established. Two sets of data from the Free Trade Zone and Hainan Free Trade Zone are selected for regression analysis, and robustness tests of various methods are carried out. This paper regresses various samples of the Hainan Free Trade Zone by region and city level to explore their characteristics in different regions. From the empirical results, it can be seen that the establishment of the Hainan Free Trade Zone has indeed promoted the economic development of the region where it is located, and this result is still significant after repeated robustness tests. Judging from the regression results by region, the establishment of the Hainan Free Trade Zone has a greater role in promoting the economic development of the eastern and western regions and it has a stronger pulling effect on the western regions than in the western regions. The policy effect of establishing a free trade zone may not be significant due to too few samples and short establishment time.
本文从物联网的产业结构和特点出发，比较分析了不同体制下市场经济中物联网产业的发展思路。我们还讨论了物联网商业模式的创新，并分析了当前物联网商业模式的不足之处。我们运用成本效益分析方法，从社会效益、经济效益、环境效益和外部性等方面进行了分析。在本文中，我们使用因子分析和定量统计来计算影响因素的权重，并采用多层次模糊评价方法对影响因素指标进行评分，计算最终得分结果，从而判断多层次模糊评价方法在判断盈利模式方面的适用性。为了验证经济区的设立是否对区域经济发展起到积极作用，建立了双重差分模型。选取自由贸易试验区和海南自由贸易试验区的两组数据进行回归分析，并对各种方法进行了稳健性检验。本文通过区域和城市层面回归分析了海南自由贸易试验区的各种样本，以探讨其在不同区域的特点。从实证结果可以看出，海南自由贸易区的设立确实促进了所在地区的经济发展，而且在经过多次稳健性检验后，这一结果仍然显著。从区域回归结果来看，海南自由贸易区的设立对东部和西部地区的经济发展起到了更大的推动作用，对西部地区的拉动作用强于东部地区。由于样本数量较少且设立时间较短，自由贸易区的设立政策效应可能不明显。
