| Summary |
Taiwan's Greenhouse Gas Reduction and Management Act Article 11 stipulates that the greenhouse gas emission control target is set in five-year phases. In response to the domestic and international net-zero emission trends, more stringent control targets for future phases are inevitable, and it is necessary to seek and propose other measures with greenhouse gas reduction benefits. Since
Taiwan has the highest motorcycle density in the world, and most are fueled motorcycles, shared transportation emphasizes the right to use vehicles rather than ownership. Moreover, vehicle electrification should have a greenhouse gas reduction effect. Therefore, this project has focused on the benefits of the Shared e-scooters in Taiwan.
In the first year (2021), we collected the use behavior of shared electric scooters, greenhouse gas emissions and research methods at home and abroad. We also developed a questionnaire survey plan and designed the content of the questionnaires. We designed survey plans and questionnaire content and conducted pre-test surveys for people aged 18 and over in Taipei and Kaohsiung cities via the landline. A random sampling method was adopted, with a total of 203 valid questionnaires completed (103 in Taipei and 100 in Kaohsiung). We also conducted a web-based questionnaire survey, and the subjects were also over 18 years old. The snowball sampling method was adopted, and we completed a total of 431 valid questionnaires were completed.
Based on the landline pre-test survey results, respondents generally understood and answered related questions. However, the proportion of respondents using shared electric motorcycles was low, presumably related to the older age of respondents. It is recommended that in the second year (2022), mobile phone surveys can be added, and the "multivariate iterative reweighting method" can be used until it is consistent with the population structure. Moreover, remote districts in Kaohsiung without shared electric motorcycle operation sites make it difficult to find suitable respondents. For the second year (2022), it is suggested to set the survey scope as the administrative districts in Kaohsiung with shared electric motorcycle operation sites. Additionally, the number of questionnaire items should be streamlined, and some question-and-answer content should be revised.
Regarding the results of the online questionnaire survey, due to the relatively young sample structure, the survey results should be regarded as the opinions of young people. Under the premise of this discussion, it can be found that the use of shared e-scooters may help reduce greenhouse gas emissions. In addition, through the structural equation model, it can be known that the positive factors that affect the “intention” of shared e-scooters include “saving money”, “environmental protection”, and “convenience”, while the negative factors are “safety”, and “identity sharing”. "Economy" has a high degree of positive influence. It is suggested that "shaping a shared image" can be used as a policy reference for promoting the use of shared e-scooters in the future |
