2. Recommendation for relationship studies (Social influences, NGV attributes):
Although the results show that almost all the hypotheses have some minor relationships
between each variable of the social influences and NGV attributes towards the behavior
intention, there are three variables that need particular focus: product performance,
product safety, and appearance. These factors seem to be the most attractive and can
influence consumers’ behavior intention; moreover, they are part of the product
attributes. To summarize, most of the product attribute factors have higher correlations
with behavior intention than the social influence factors. Therefore, the researchers
suggest that PTT should concentrate on the product itself especially product performance,
product safety, and appearance to increase the number of NGV users until they can
achieve their targets. For high impact factors, safety and quality control are of the crucial
concern for the consumers. All precautionary measures should be taken to avoid any
occurrence of accidents, such as CNG tank explosions, which are very effective in
scaring people away from using NGV. PTT should arrange training programs on a
regular basis for their installation and maintenance personnel to assure their high quality
and performance standard to the general public. In addition, PTT should arrange the
seminar workshop on a periodical basis for imparting correct knowledge about NGV to
the people who are involved, and organize the NGV product in order to distribute the
accurate information on NGV to the consumers in the same direction. Then, the company
should use the media or communication strategy to continuously feed factual information
on NGV products to avoid misunderstandings about NGV. Both measures will enhance
the good image of the product and the PTT organization.
