作為秉持專業、品質、環保、節能減碳理念的吊頂系統承包業者而言，如何精益求精，提供更好的服務與施工給建築工程承包單位，來創造一個愉快、舒適的健康生活環境是本研究目標，討論建築工程承包單位選擇分包商決定性因素，藉此提升雙方的共識，減少建築工程承包單位與分包商的交易成本與時間成本。
研究以吊頂系統Ｈ公司為例，利用線性機率模型(Linear Probability Model , LPM)為研究方法，透過問卷發放給採用過H公司吊頂系統之建築工程承包單位，與未採用H公司吊頂系統之建築工程承包單位，作為問卷收集之資料來源。問卷總發放110份，回收有效樣本為104份，問卷有效回收率為95%。
本研究運用計劃行為理論、科技接受模型、承諾信任理論與實際影響因素探討建築工程承包單位選擇分包商決定性因素，研究結果如下：
一、建築工程承包單位選擇H公司為分包商的「行為意願」明顯受到計劃行為理論的「行為態度」、「主觀規範」、「知覺行為控制」與承諾信任理論的「關係承諾」與「信任」因素所影響。
二、建築工程承包單位選擇H公司為分包商的「行為態度」明顯受科技接受模型的「認知有用性」與「認知易用性」因素所影響。
三、建築工程承包單位選擇H公司為分包商的「關係承諾」明顯受到「共同價值觀」因素所影響。
四、建築工程承包單位選擇H公司為分包商的「信任」明顯受到「溝通」因素所影響。

SUMMARY
The object in this study is the ceiling system’s company, H Ld., and this study carries on the collection of the data from the architectural contractors who choose or not to choose H Ld. as their subcontractors through the method of LPM (Linear Probability Model). Out of 110 questionnaires sent, 104 valid questionnaires were retrieved. The effective response rate is 95%.
TPB, TAM, CTT and the realistic factors are applied to examine the determinants of the architectural contractor’s selection of a subcontractor. The major findings of this study are stated as below:
1. The attitude toward behavior, subject norms and perceived behavioral control of TPB and the relationship commitment and trust of CTT would affect significant intention of the behavioral intention of architectural contractors.
2. The perceived usefulness and perceived ease of use would affect significant intention of the attitude toward behavior of architectural contractors.
3. The shared value would affect significant intention of the relationship commitment of architectural contractors.
4. The communication would affect significant intention of the trust of architectural contractors.

INTRODUCTION

The purpose of this study is to determine the architectural contractor’s selection of a subcontractor. The object is the ceiling system’s company, H Ld., and this study carries on the collection of the data from the architectural contractors who choose or not to choose H Ld. as their subcontractors.
Theory of Plan Behavior (Ajzen, 1985), Technology Acceptance Model (Davis, 1989), Commitment Trust Theory (Morgan & Hunt, 1994) and the realistic factors are applied to examine the determinants of the architectural contractor’s selection of a subcontractor. This study uses the method of LPM (Linear Probability Model) as the statistic method.
The result shows that the attitude toward behavior, subject norms and perceived behavioral control of TPB and the relationship commitment and trust of CTT would affect significant intention of the behavioral intention of architectural contractors.

MATERIALS AND METHODS

This research uses questionnaires from the architectural contractors who choose or not to choose H Ld. Out of 110 questionnaires sent, and 104 valid questionnaires were retrieved. The effective response rate is 95%, with more details shown in Table 1.

RESULTS AND DISCUSSION

In this study, LPM model and multiple regression analysis are both applied, with more details shown in the model 1 to model 4.

Model 1: The dependent varaiable, Y, is the behavioral intention of architectural contractors.
Y=−2.32+0.15X1+0.23X2+0.22X3+0.09X4+0.1X5−0.07D11−0.02D12−0.03D21+0.26D22−0.03D23−0.09D31+0.06D32−0.03D41+0.07D42−0.16D51−0.1D52

CONCLUSION

The major findings of this study are stated as below:
1. The attitude toward behavior, subject norms and perceived behavioral control of TPB and the relationship commitment and trust of CTT would affect significant intention of the behavioral intention of architectural contractors.
2. The perceived usefulness and perceived ease of use would affect significant intention of the attitude toward behavior of architectural contractors.
3. The shared value would affect significant intention of the relationship commitment of architectural contractors.
4. The communication would affect significant intention of the trust of architectural contractors.
However, the results are not all the same as the assumption in this study such as the realistic factors that may cause by sampling bias and that would be worth to study further in the future.
