BUACC5931: Research Report on ISO 9000 Certification Impact in China

This report presents an empirical analysis of the impact of ISO 9000 certification on service firms in China, utilizing chi-square tests, ANOVA, and regression analysis. The study, based on secondary data from the National Bureau of Statistics of China, investigates the relationship between ISO 9000 certification and factors such as foreign direct investment (FDI), financial attributes, and business performance. The findings suggest that ISO 9000 certification is not a prerequisite for attracting overseas investment in Chinese service firms, although it does have a positive impact on profit through better quality management. The report provides descriptive and inferential statistics, including t-tests and correlation analyses, to support its conclusions, and discusses the implications of the findings for businesses. The study also acknowledges limitations and suggests areas for further research, offering valuable insights into the role and impact of ISO 9000 certification in the Chinese business context.

2IMPACT OF ISO 9000 CERTIFICATION IN CHINA
Executive Summary
The report presents the empirical analysis which includes the chi-square test and
regression analysis to check the potential impact of ISO 9000 Certification in China. The test
concludes that for overseas investment, it is not necessary to have an ISO 9000 certification
to the service firms of China. Here, it is recommended to the firms to attract the overseas
investment there is no need of ISO certification. They should focus on other factors that may
have impact on attracting the FDI. However, the regression result shows that the greater
impact on profit is found from the return on asset followed by the certification. Here, ISO
certificate raises the profit. This is because of better quality management which is approved
by the certificate of ISO 9000.
Back ground of the Study
ISO 9000 implies a number of international standards for quality assurance and
management and this provides the companies easy documentation system to maintain an
effective quality system. This quality management systems standard was introduced in 1987
an since then it is extensively used by the companies all over the world (Chatzoglou,
Chatzoudes & Kipraios, 2015). The purpose of the study is to check the relationship between
the certification and FDI. Moreover, the impact of this standard along with other factors on
the revenue of the company. The research objective is mentioned in the form of research
hypothesis:
Research Aim
The interest of the study is to find out the impacts of adoption of ISO 9000.
Hence, the research question,
1. What is the impact of ISO certification on the company’s financial attributes like,
source of capital, assets, equity and demographics of the employees?

3IMPACT OF ISO 9000 CERTIFICATION IN CHINA
2. Is there any relationship between above mentioned variables and the adoption of ISO
9000 certification?
In this report, the first section is about introduction and a brief literature review is
discussed in the very next section. Third section describes the methodology and fourth
section discusses the findings and results. Fifth and sixth section is about discussion and
managerial advices and limitation and further research respectively.
Literature Review
The ISO certification provides directly or indirectly some extent of non-monetary
benefits. There is a lack of research that has found the impact of ISO on monetary gains
(Fikru, 2014). There is a study in Nigeria, that reveals the positive impact of ISO certification
on raising the total amount of return from the asset. The firms with ISO certification have
larger amount of sales due to hike in exports and thus the productivity is higher (Goedhuys &
Sleuwaegen, 2013). The spread of ISO 9000 certification in under developed countries that
are trying to be developed turn out to create the rise in inward FDI and the rise of export in
the trade flow (Allur, Arana-Landin & Heras Saizarbitoria, 2014). There are few papers that
describes the objective, standard and implication of quality management and performance of
the certified organizations that are improved. Now, there studies that says rise in the
performance and quality can raise the profit of those organizations (Terziovski & Guerrero,
2014). The number of studies is very less where researchers have estimated the financial
impacts of ISO certification. A research has found a positive relation with stock prices on the
particular day of being certified with ISO 900 (Terziovski & Guerrero, 2014). Again there is
a study that have noticed a positive reaction in stock market for the introduction of ISO 9000
certification (Lakhal, 2014). However, this is found that the impact was only for small firms
not for the large firms (Djofack & Camacho, 2017). There is a relationship between ISO
certification and superior performance in financial part of the company (Cai, & Jun, 2018).

4IMPACT OF ISO 9000 CERTIFICATION IN CHINA
This implies that the rise in stock price indicates a better position in financial sector which
has potential to raise the profit of the company. There is a study on 160 Australian
companies, it shows the positive impacts of ISO 9000 on relation with its customers, products
and services, the product quality awareness of the company, satisfaction of the customers,
management of the company and a relative growth of the company, with its competitors
(Ong, Kathawala & Sawalha, 2015). Similarly, another study conducted in UK has claimed
that the certification has contributed positively in raising the number of new contracts,
reducing the customer audits, improving the market relation and giving an international
exposure (Kunnaala, Lappalainen & Tapaninen, 2013). Moreover, there are studies that
claims that the ISO 9000 has a contribution in raising the operational and business
performance which is reflected by the attributes like collection of capital from different
sources, assets and equities which has direct linkage in raising business and the profit
(Georgiev & Georgiev, 2015). Again there are few studies which has claimed that the ISO
certification has no role in improvement of quality management, profitability and
productivity (Grela, 2015). In this case, it is necessary to check the profitability of a firm due
to ISO certification and the attributes that are linked with the financial performance of a firm.
Methodology
In order to find the significant evidence for the answers of research questions, a large
data is collected on service firms in China. The data is secondary and collected from the
National Bureau of Statistics of China from an economic census which was conducted in
2008. A chi-square test is conducted to find the association between FDI and ISO
certification. There is ANOVA test and independence test to check the mean difference in the
variables of certified and non-certified companies. The Pearson correlation is computed to
check the relationship between the variables sales, profit, asset, capital paid, capital from
others, return on sales and return on asset and ISO 9000 certification.

Analysis and Findings
Descriptive Statistics
The descriptive statistics is presented for each variable in this section of the report.
Each variable is discussed one by one in the following section.
The table 1 shows the certification year for the companies and it is found that the
certification year is not known for each service firm as the missing value is recorded for 5257
companies. Hence, this variable cannot be included in the analysis.

The table 2 presents the dummy for certification and it has recorded that the 5257 out
of 5717 companies which is 92% of the sample, are not certified with the ISO 9000. So, there
is very few number of companies in which the study is focused on.

The table 5.1, 5.2 and 5.3 present some of the interesting features of the service firms
of China and few are mentioned here. The average number of employee in each service firm
is approximately 45. From these employees on an average 2 employees have masters and
doctor degree, 12 employees have bachelor degree, 13 employees have diploma, 13
employees have completed high school and rest of them have lesser education. 50% of the

7IMPACT OF ISO 9000 CERTIFICATION IN CHINA
firms have less than 23 employees and they are less likely to recruit employees who has
completed masters or doctorate. The distribution of educational status at different level and
the number of employees are right skewed. The firms have at least 11 employees and at most
969 employees in China.

The below table is the inferential table for the independence t-test where the certification
dummy is used as a factor. This shows the comparison of the factors that are influenced by

9IMPACT OF ISO 9000 CERTIFICATION IN CHINA
the ISO 9000 certification. Now, if the p-value for the equal variance is greater than 0.05 then
the assumption of equal variance is not violated otherwise there is unequal variance. Now
looking at the p-value of t-stat for all variables, it is found that the p-value is greater than 0.05
for other level of educational qualification, capital from state and capital from overseas and
percentage of FDI. This implies that these variables are not significantly different for the
certified and non-certified companies. This implies that the mean value of employee number,
master and doctor, bachelor, diploma, high school, sales, profit, asset, equity, capital paid,
capital from other, return on sales and return on asset off certified and uncertified companies
are significantly different.

In the below table the column “sig” presents the p-value for the test of hypothesis. If
the p-value is less than 0.05 then it can be said that there is a significant difference between
the mean values. It is found that the p-value is less than 0.05 for the sales, profit, asset, capital
paid, capital from others, return on sales and return on asset. Hence, the mean value of these
variables are significantly different.

13IMPACT OF ISO 9000 CERTIFICATION IN CHINA
Chi-square test
The table 6 presents the result of chi-square test. From the table below it is found
that the chi-square test statistic is equal to 0.723 and the corresponding p-value is 0.669. The
decision rule is to reject the null hypothesis if the p-value of the test statistic is less than the
given significance level which is 0.05 otherwise, retain the null hypothesis. Here, the p-value
for the test statistic is greater than 0.05. This implies there is no association between the
overseas investment and the ISO 9000 certification. So, here it can be concluded that for
overseas investment, it is not necessary to have an ISO 9000 certification to the service firms
of China.

Correlation
The table 9 presents the value of correlation coefficients between the dependent
variable profit and the independent variables that are asset, equity, capital from different
sources, return from sales and asset, FDI, age of the company and the most important factor,
certification dummy. It is found that the correlation is strong for asset (r=0.562), followed by
the equity (r=0.499) and source of capital (r=0.334, 0.189 and 0.294). The weak correlation is

14IMPACT OF ISO 9000 CERTIFICATION IN CHINA
found for FDI (r=0.064 and 0.076). These implies that the profit of the service firm is deeply
associated with the variables that have strong correlation.

Discussion and Managerial Advices
The chi-square test concludes that for overseas investment, it is not necessary to have
an ISO 9000 certification to the service firms of China. Here, it is recommended to the firms
that to attract the overseas investment there is no need of ISO certification. They should focus
on other factors that may have impact on attracting the FDI (Prado-Román et al. 2015).
However, the regression result shows that the greater impact on profit is found from the
return on asset followed by the certification. Here, ISO certificate raises the profit. This is
because of better quality management which is approved by the certificate of ISO 9000.
Limitation and Further Research
There are few limitation of this study and the most important limitation is related to
the sample data. For the first research hypothesis, 50% of data should be collected from those

16IMPACT OF ISO 9000 CERTIFICATION IN CHINA
companies which have ISO certificate or an alternative way is to choose the firms in such
way so that 50% of the sample has overseas investment. This is very crucial in order to
increase the goodness of the test. The result for second research hypothesis shows that the
model can only predict the 38.8% variance in profit. It can be said that there must be few
variables which can raise the prediction power of model so that it can predict more variance
in profit.
It is very important to choose the sample size efficiently and wisely to get an
unbiased, consistent and efficient results. Again, there is needed a wide scale of study on the
relevant literature review to get the exposure of other variables that have impact on the profits
of the service firm in China.
