INTRODUCTION
1.1 Background of the Study
According to figures from the Ministry of Industry and Commerce, at present, small and medium enterprises account for more than 85% of enterprises in Vietnam, with registered capital of nearly 2,313,857 billion dongs (equivalent to 121 billion dollars) and 100% having Internet access While more and more customers are looking for new products and trade opportunities with Southeast Asian countries, Vietnamese enterprises are also seeking new opportunities to reach them through e-commerce Along with maintaining domestic operations actively, Vietnam will definitely continue to receive more attentions from importers in a near future (Mr Vincent Wong, Senior Managing Director of Business Development and Customer
Services Department of Group Alibaba.com shared).
Năm 2012 Hiệp hội Thương mại điện tử Việt Nam (VECOM) tiến hành hoạt động xây dựng Chỉ số Thương mại điện tử với mong muốn hỗ trợ các cơ quan, tổ chức và doanh nghiệp nhanh chóng đánh giá được tình hình ứng dụng thương mại điện tử trên phạm vi cả nước cũng như tại từng tỉnh, thành phố trực thuộc Trung ương Chỉ số
Thương mại điện tử, gọi tắt là EBI (E-business Index), giúp cho các cơ quan, tổ chức và doanh nghiệp có thể đánh giá một cách nhanh chóng mức độ ứng dụng thương mại điện tử
và so sánh sự tiến bộ giữa các năm theo từng địa phương, đồng thời hỗ trợ việc đánh giá,
so sánh giữa các địa phương với nhau dựa trên một hệ thống các chỉ số
Như vậy, ở Việt Nam hiện tại chỉ có Hiệp hội Thương mại điện tử Việt Nam (VECOM) đã xây dựng chỉ số ứng dụng thương mại điện tử để đánh giá mức độ ứng dụng thương mại điện tử của các doanh nghiệp và tổ chức trong nước Nhưng những chỉ số này mới chỉ mang tính thống kê điều tra đưa ra mức ứng dụng thương mại điện
tử hàng năm chứ không đưa ra được những chỉ số đánh giá giúp cho các doanh nghiệp nhận biết: năng lực của doanh nghiệp của mình có thể ứng dụng thương mại điện tử được không; Doanh nghiệp cần phải đầu tư như thế nào, những vấn đề nào cần phải giải quyết để có thể áp dụng thương mại điện tử vào kinh doanh

PRESENTATION, ANALYSIS AND INTERPRETATION OF
RESULTS
This chapter presents the analysis and interpretation of the resuslt To present the sequence of findings of the study, the discussions were arranged according to the stated problems:
4.1 Respondents’ profile
4.2 Factors afecting the adoption of e-commerce
In order to analyze the factors of ecommerce model advantage and SMES‟ readiness
to adopt ecommerce, a Factor Analysis was conducted using SPSS 16.0
Factor analysis was performed with 28 variations of ecommerce model advantage and SMES‟ readiness to adopt ecommerce in Vietnam Through the analysis, the variables are at the request of the model is: KMO coefficient values (Kaiser-Meyer-Olkin) greater than 0.5, the Fator loading greater than 0.5 Analysis method is chosen to be Principal components analysis with varimax rotation.The results are as follows:
From Factor Analysis, two tables were chosen for the analysis The first table is called
“KMO and Bartlett‟s test”, which presents the adequacy of the sampling for each variable
According to Table 4.4, the result of KMO for Capacity of the firm is 0.85, a satisfactory
result:
Table 4.4: KMO and Bartlett's Test
Kaiser-Meyer-Olkin Measure of Sampling
Bartlett's Test of Sphericity
Approx Chi-Square 4.302E3
The second table is Rotated Component Matrix which reports the factor loadings for each variable on the components or factors after rotation The factor analysis used principal components in order to extract the maximum variance from the items To minimize the number of items that have high loadings on any given factor, a varimax rotation was utilized
The Rotated Component Matrix in Table 4.5 shows that contrary to the original
model, the items of Effectiveness were loaded into five components, which means that
Trang 8Effectiveness is divided into five factors In Table 4.5 there is 1 indicator to be rejected from
the list (Improve customer service) because this item have loading smaller than 0.5
After removing one indicator we perform factor analysis with the remaining 27 variables The analytical results are as follows:
In the Table 4.6 (KMO and Bartlett‟s test), the result of KMO for Capacity of the firm is
0.921, a satisfactory result
Table 4.6: KMO and Bartlett's Test
Kaiser-Meyer-Olkin Measure of Sampling Adequacy 0.921
Bartlett's Test of Sphericity Approx Chi-Square 4.184E3
The Rotated Component Matrix in Table 4.7 shows that contrary to the original
model, the items of Effectiveness were loaded into five components, which means that
Effectiveness is divided into five factors Table 4.7 also shows that all items have loading
greater than 0.5 and loaded stronger on their associated factors than on others, and there isn‟t any indicator to be rejected from the list
After performing factor analysis of 27 variables as above, we have 5 factors are drawn:
- Capacity of the firm
- Compatibility
- Easiness
- Usefulness
- Effectiveness
Adjust the research model
Through the above analysis shows that from 27 variables to measure the factors affecting the adoption of e-commerce model developed for small and medium enterprises in Viet Nam have been a change in content
Thus, the research model after factor analysis results are adjusted as follows (Figure 2.1) with the assumptions of the model are:
H1 Capacity of firm affects e-commerce adoption
H2 The ease of use affects e-commerce adoption
H3 The usefulness affects e-commerce adoption
Trang 9H4 Effectiveness affects e-commerce adoption
H5 Compatibility of e-commerce for the value, work practices, and technology in the firm affects e-commerce adoption
Test the factors with Cronbach Alpha
After performing factors analysis, the factors were drawn Perform testing by Cronbach Alpha for each factors to measure a set of questions in each section were drawn factors to link together or not Many researchers agree that the Cronbach alpha coefficient >=0.6 is used and corrected iTerm - Total correlation must be greater than 0.3 (Mong Hoang Trong and Nguyen Ngoc Chu, 2005)
5 factors were achieved Cronbach alpha coefficient and corrected iTerm - Total correlation as necessary level, to ensure the conditions for inclusion in the next model analysis
4.4 Logistic Regression
Logistic regression is used to predict a categorical (usually dichotomous) variable from
a set of predictor variables With a categorical dependent variable, discriminant function analysis is usually employed if all of the predictors are continuous and nicely distributed; logit analysis is usually employed if all of the predictors are categorical; and logistic regression is often chosen if the predictor variables are a mix of continuous and categorical variables and/or

Model chi-square The overall significance is tested using what SPSS calls the Model Chi square, which is derived from the likelihood of observing the actual data under the assumption that the model that has been fitted is accurate There are two hypotheses to test in relation to the overall fit of the model:
H0 The model is a good fitting model
H1 The model is not a good fitting model (i.e the predictors have a significant effect)

The value of -2 Log likelihood in step 4 equals to 71.333 and it has the lowest value in 4 step
The results of Table 4.18: Omnibus Tests of Model Coefficients and Table 4.19:
Model Summary, we see that -2 Log likelihood = 71,333 is not high, acceptable because only 0:28 of the Chi-square (71.333 /201.993)
According to the example in the book "Data Analysis with SPSS research" (Hoang Trong and Nguyen Mong Ngoc Chu, 2005), value of "-2 log likelihood" is only 0.5 value of
"Chi-square"

Nagelkerke‟s R2 is part of SPSS output in the „Model Summary‟ table and is the most-reported of the R-squared estimates In our case it is 0.853, indicating a moderately strong relationship of 85.3% between the predictors and the prediction
Classification Table Rather than using a goodness-of-fit statistic, we often want to look at the
proportion of cases we have managed to classify correctly For this we need to look at the classification table printed out by SPSS, which tells us how many of the cases where the observed values of the dependent variable were 1 or 0 respectively have been correctly
predicted In the Classification Table (Table 4.20), the columns are the two predicted values
of the dependent, while the rows are the two observed (actual) values of the dependent In a perfect model, all cases will be on the diagonal and the overall percent correct will be 100%
In this study, 91.2% were correctly classified for the not utilize e-commerce group and 87.2% for the utilize e-commerce group Overall 89.5% were correctly classified

Variables in the Equation The Variables in the Equation table (Table 4.21) have several
important elements The Wald statistic and associated probabilities provide an index of the significance of each predictor in the equation The Wald statistic has a chi-square distribution
The simplest way to assess Wald is to take the p-values, and if less than 0.05, reject the null hypothesis as the variable does make a significant contribution In this case, we see that All four factors are p-value less than 0.05 Such factors
H1 -Capacity of firm affects e-commerce adoption;
H2 -The ease of use affects e-commerce adoption;
H3 -The usefulness affects e-commerce adoption;
H5 -Compatibility of e-commerce for the value, work practices, and technology in the firm affects e-commerce adoption,
affects predictions
