Micro-Enterprise Survey 2009 - Cameroon

Abstract
---------------------------

This research of registered businesses with one to four employees was conducted in Cameroon from June 1 to Oct. 15, 2009, at the same time with 2009 Cameroon Enterprise Survey. Interviews with 120 establishments were completed.

Micro-Enterprise Survey topics include firm characteristics, gender participation, access to finance, annual sales, costs of inputs/labor, workforce composition, bribery, licensing, infrastructure, trade, crime, competition, capacity utilization, land and permits, taxation, informality, business-government relations, innovation and technology, and performance measures. Over 90% of the questions objectively ascertain characteristics of a country's business environment. The remaining questions assess the survey respondents' opinions on what are the obstacles to firm growth and performance.

Geographic coverage

National

Analysis unit
---------------------------

The primary sampling unit of the study is a registered establishment with one to four employees.

Universe
---------------------------

The whole population, or the universe, covered in the Enterprise Surveys is the non-agricultural economy. It comprises: all manufacturing sectors according to the ISIC Revision 3.1 group classification (group D), construction sector (group F), services sector (groups G and H), and transport, storage, and communications sector (group I). Note that this population definition excludes the following sectors: financial intermediation (group J), real estate and renting activities (group K, except sub-sector 72, IT, which was added to the population under study), and all public or utilities-sectors.

Kind of data
---------------------------

Sample survey data [ssd]

Sampling procedure
---------------------------

The sample for registered establishments in Cameroon was selected using stratified random sampling. Two levels of stratification were used in the Cameroon Micro-Enterprise Survey sample: firm sector, and geographic region.

For industry stratification, the universe was divided into one manufacturing industry, one services industry (retail) and one services residual sector.

Regional stratification was defined in terms of the geographic regions with the largest commercial presence in the country. Littoral (Douala), Centre (Yaoundé) and West (Bafoussam) were the three metropolitan areas selected in Cameroon.

Two frames were used for Cameroon. The first was obtained from the Chamber of commerce of Cameroon (2008). The sample frame collected information for 8,000 companies in various sector of activities spread in all the regions of Cameroon. The second frame (the panel sample) consisted of enterprises interviewed for the Enterprise Survey in 2006, which were to be re-interviewed where they were in the selected geographical regions and met eligibility criteria. Both database contained the following information:
-Name of the firm
-Contact details
-ISIC code
-Number of employees.

The percentage of confirmed non-eligible units as a proportion of the total number of sampled establishments contacted for the survey was 58.5% (971 out of 1,659 establishments for the Enterprise Survey and Micro-Enterprise Survey samples, including panel establishments).

Breaking down by industry, the following numbers of establishments were surveyed: Manufacturing - 36, Sector 52 -3, Other Services - 82.

Mode of data collection
---------------------------

Face-to-face [f2f]

Research instrument
---------------------------

The current survey instruments are available:
- Core Questionnaire + Manufacturing Module [ISIC Rev.3.1: 15-37]
- Core Questionnaire + Retail Module [ISIC Rev.3.1: 52]
- Core Questionnaire [ISIC Rev.3.1: 45, 50, 51, 55, 60-64, 72]
- Screener Questionnaire

The “Core Questionnaire” is the heart of the Enterprise Survey and contains the survey questions asked of all firms across the world. There are also two other survey instruments- the “Core Questionnaire + Manufacturing Module” and the “Core Questionnaire + Retail Module.” The survey is fielded via three instruments in order to not ask questions that are irrelevant to specific types of firms, e.g. a question that relates to production and nonproduction workers should not be asked of a retail firm. In addition to questions that are asked across countries, all surveys are customized and contain country-specific questions. An example of customization would be including tourism-related questions that are asked in certain countries when tourism is an existing or potential sector of economic growth.

The standard Enterprise Survey topics include firm characteristics, gender participation, access to finance, annual sales, costs of inputs/labor, workforce composition, bribery, licensing, infrastructure, trade, crime, competition, capacity utilization, land and permits, taxation, informality, business-government relations, innovation and technology, and performance measures. Over 90% of the questions objectively ascertain characteristics of a country’s business environment. The remaining questions assess the survey respondents’ opinions on what are the obstacles to firm growth and performance.

Cleaning operations
---------------------------

Data entry and quality controls are implemented by the contractor and data is delivered to the World Bank in batches (typically 10%, 50% and 100%). These data deliveries are checked for logical consistency, out of range values, skip patterns, and duplicate entries. Problems are flagged by the World Bank and corrected by the implementing contractor through data checks, callbacks, and revisiting establishments.

Response rate

Complete information regarding the sampling methodology, sample frame, weights, response rates, and implementation can be found in "Description of Cameroon Implementation 2009" in "Technical Documents" folder.

摘要
---------------------------
本研究针对拥有一到四名员工的注册企业在喀麦隆的调研于2009年6月1日至10月15日进行，与2009年喀麦隆企业调查同步进行。共完成了120家企业的访谈。
微型企业调查主题包括企业特征、性别参与、融资渠道、年度销售额、投入/劳动力成本、劳动力构成、贿赂、许可、基础设施、贸易、犯罪、竞争、产能利用率、土地与许可证、税收、非正规性、企业与政府关系、创新与技术以及绩效指标。超过90%的问题客观地确认了国家商业环境的特点。其余问题评估了调查受访者对企业增长和绩效障碍的看法。
地理覆盖范围
---------------------------
全国
分析单元
---------------------------
本研究的主要抽样单元为拥有一到四名员工的注册企业。
总体
---------------------------
企业调查的总体，即研究范围，涵盖非农业经济。它包括：根据修订版3.1的ISIC行业分类（D组），所有制造业部门、建筑业部门（F组）、服务业部门（G组和H组）以及交通运输、仓储和通信部门（I组）。请注意，以下部门不包括在内：金融中介（J组）、房地产和租赁活动（K组，除子部门72，IT，该子部门被纳入研究总体之外），以及所有公共或公用事业部门。
数据类型
---------------------------
样本调查数据 [ssd]
抽样程序
---------------------------
喀麦隆注册企业的样本是通过分层随机抽样选取的。喀麦隆微型企业调查样本使用了两个分层级别：企业部门和地理区域。
在行业分层中，总体被划分为一个制造业部门、一个服务业部门（零售）和一个服务业剩余部门。
区域分层是以国家中商业存在最大的地理区域为定义的。在喀麦隆，选定的三个大都市区为沿海（杜阿拉）、中部（雅温得）和西部（巴富萨姆）。
喀麦隆使用了两个框架。第一个框架来自喀麦隆商会（2008年）。样本框架收集了分布在喀麦隆所有地区的8000家公司的各种活动部门的信息。第二个框架（样本面板）包括2006年接受企业调查的企业，这些企业在选定的地理区域内且符合资格条件的情况下将被重新访谈。两个数据库都包含以下信息：公司名称、联系详情、ISIC代码和员工人数。
作为样本调查中确认的非合格单位占总样本调查中联系到的总单位的百分比是58.5%（包括971家企业和1659家企业和微型企业调查样本，包括面板企业）。
按行业细分，以下数量的企业接受了调查：制造业 - 36家，52部门 - 3家，其他服务业 - 82家。
数据收集方式

研究工具
---------------------------
当前调查工具如下：
- 核心问卷 + 制造业模块 [ISIC Rev.3.1: 15-37]
- 核心问卷 + 零售模块 [ISIC Rev.3.1: 52]
- 核心问卷 [ISIC Rev.3.1: 45, 50, 51, 55, 60-64, 72]
- 筛选问卷

“核心问卷”是企业调查的核心，包含所有世界范围内企业都会被问到的问题。还有两种其他调查工具——即“核心问卷 + 制造业模块”和“核心问卷 + 零售模块”。调查通过三种工具进行，以确保不向特定类型的企业提出不相关的问题，例如，与生产和非生产工人相关的问题不应对零售企业提问。除了跨国家提出的问题外，所有调查都是定制的，并包含具有国家特定问题的内容。定制的例子包括在旅游业是现有或潜在经济增长部门的国家中询问与旅游业相关的问题。
标准的企业调查主题包括企业特征、性别参与、融资渠道、年度销售额、投入/劳动力成本、劳动力构成、贿赂、许可、基础设施、贸易、犯罪、竞争、产能利用率、土地与许可证、税收、非正规性、企业与政府关系、创新与技术以及绩效指标。超过90%的问题客观地确认了国家商业环境的特点。其余问题评估了调查受访者对企业增长和绩效障碍的看法。
数据清洗操作
---------------------------
数据输入和质量控制由承包商实施，并将数据以批量形式（通常是10%、50%和100%）交付给世界银行。这些数据交付将进行逻辑一致性、超出范围值、跳过模式和重复条目的检查。问题由世界银行标记并由实施承包商通过数据检查、回访和重新访问企业进行纠正。
