Longitudinal Small Business Survey, 2015-2017: Secure Access

The <i>Longitudinal Small Business Survey</i> (LSBS) is a large-scale telephone survey of UK small business owners and managers, commissioned by the Department for Business, Innovation and Skills (BIS). This survey is the latest in a series of annual and biennial Small Business Surveys (SBS) dating back to 2003. From 2015, the survey methodology changed to include a longitudinal tracking element. A large sample size was recruited in Year One (2015) to establish a panel of businesses that will be re-surveyed in subsequent years. This will allow a detailed analysis of how combinations of factors affect business performance.<br>
<br>
The LSBS is intended to:<ul><li>improve the understanding of what drives and constrains business performance and growth by addressing evidence gaps relating to the lags between many business activities and associated performance outcomes</li><li>provide improved data on current business performance and the factors that affect this. The larger survey size will provide more reliable findings for key sub-groups of the business population and in relation to activities such as seeking finance which are only relevant to part of the sample.</li></ul>The data currently available includes a cross-sectional and a panel data file which include respondents for Year One (2015), Year Two (2016) and Year Three (2017). It is the intention to repeat the current survey with an updated sample each year for five years. Further information and research reports are available on the GOV.UK <a class="external" href="https://www.gov.uk/government/collections/small-business-survey-reports" title="Small Business Survey reports">Small Business Survey reports</a> webpage.<br>

《纵向小型企业调查》（Longitudinal Small Business Survey，LSBS）是由英国商业、创新与技能部（Department for Business, Innovation and Skills，BIS）委托开展的大规模电话调查，对象为英国小型企业所有者及管理者。该调查是2003年起年度及双年度《小型企业调查》（Small Business Survey，SBS）系列的最新成果。2015年起，调查方法新增纵向跟踪元素：首年（2015年）招募大样本企业建立面板，后续年份重复调查，以深入分析多因素组合对企业绩效的影响。

LSBS旨在：
- 通过填补企业活动与绩效结果间的证据空白，增进对绩效及增长驱动/制约因素的理解；
- 提供更完善的当前绩效及影响因素数据。更大样本量可为关键子群体及融资需求等局部相关活动提供更可靠结论。

现有数据含横截面与面板文件，覆盖2015（首年）、2016（次年）、2017（第三年）受访者。计划未来五年每年用更新样本重复调查。更多信息及报告见英国政府网（GOV.UK）《小型企业调查报告》页面（链接：https://www.gov.uk/government/collections/small-business-survey-reports）。
