[Objective] The present paper aimed to explore and design the platform architecture of agricultural machinery socialization service supply and demand docking, provide agricultural machinery socialization services scientifically and reasonably according to the needs of farmers, and coordinate the management of massive agricultural machinery socialization service data and information, so as to promote the development of agricultural informatization, so as to improve the management level of agricultural machinery and the quality and efficiency of agricultural machinery socialization services, and provide effective support for the transformation and upgrading of modem agriculture. [Method] Factor analysis was used to sort out the core requirements of users for the platform, divide the functional modules of the platform, and design the platform architecture based on this. The service blueprint theory was exploringly applied to the socialization of agricultural machinery services, which depicted the blueprint of the supply and demand docking platform of agricultural machinery socialization services, displayed various activities in the process of socialized agricultural machinery services, sorted out the service process, and showed the integrity of the platform architecture design in a visual form. [Result] The data variation explained by the four main factors was greater than 5%, and the cumulative variance contribution rate was 85. 32%, and the four main factors could be extracted, which were named as platform management optimization function requirements, agricultural machinery operation service function requirements, agricultural machinery information service function requirements and agricultural machinery supporting service function requirements to comprehensively express the functional requirements of the agricultural machinery socialized service supply and demand docking platform. Based on the results of factor analysis function division and the process of agricultural machinery socialized service described in the service blueprint, the architecture of the agricultural machinery socialized service supply and demand docking platform was designed. [Conclusion] With the adjustment of China's population structure, the shortage of labor in agricultural production, and the increasing demand of farmers for agricultural machinery socialization services, the construction of agricultural machinery socialization service platform is the general trend, and it is necessary to conduct in-depth research and gradual improvement in the future to promote the final construction and implementation of the platform.

In order to investigate the influence of different styles of modified "new Tang costume" on consumers′ perception, 18 different models of modified "new Tang costume"were selected from 3 aspects: collar, lapel and sleeves. The data of consumers′ perceptual evaluation of different styles of modified "new Tang costume" were obtained through questionnaire survey, and the three major perceptual factors were extracted by using mean analysis and factor analysis to quantify the perceptual evaluation, and then the regression model of perceptual factors and overall perceptual evaluation was established by combining STIRPAT model and ridge regression method. The results show that the perceptual factors influencing the style design of the modified "new Tang costume"are mode factor, visual factor and occasion factor; among them, the occasion factor has the highest elasticity on the perceptual evaluation of the modified "new Tang costume"and is the main factor influencing the perceptual impression of consumers, followed by the mode factor and the visual factor.
