Purpose

The construction sector (CNS) occupies a very unique position in any economy depending on whether developed or developing economy. The size and linkages of the CNS are expected to be high to help push or pull the economy from developing to developed economy through elaborate forward and backward linkages, a cardinal aim of developing economies. This paper aims to investigate the forward and backward linkages of the CNS in the Nigerian economy.

Design/methodology/approach

In contrast to the traditional input–output analysis to assess sectoral economic performance and production interdependence, this paper used econometric techniques, including unit root test, cointegration test and Granger causality test to analyze the data. Time-series data (TSD) for the study were extracted from United Nations Statistical Department database.

Findings

The result indicated that the CNS has low forward linkages but high backward linkages to virtually all the sectors of the Nigerian economy. Thus, the outputs of construction mainly satisfy the manufacturing and other activities.

Originality/value

The paper gives an insight into the construction on backward linkages but less extensive forward linkages. The paper recommends a massive local content development of sector to deepen backward and forward linkages and thus helps pull or push weak sectors out of stagnation.

评估建筑业与尼日利亚经济其他部门之间的联系

目的

建筑业（CNS）在任何经济体中都占有非常独特的地位，具体取决于发达经济体还是发展中经济体。中枢神经系统的规模和联系预计将很高，以通过精细的前向和后向联系帮助推动或拉动经济从发展中经济体向发达经济体转变，这是发展中经济体的主要目标。本文旨在调查 CNS 在尼日利亚经济中的前向和后向联系。

设计/方法论/途径

与传统的投入产出分析来评估部门经济绩效和生产相互依存性不同，本文使用计量经济学技术，包括单位根检验、协整检验和格兰杰因果关系检验来分析数据。该研究的时间序列数据（TSD）是从联合国统计部数据库中提取的。

发现

结果表明，CNS 与尼日利亚经济的几乎所有部门的前向联系较低，但后向联系较高。因此，建筑业的产出主要满足制造和其他活动。

原创性/价值

本文深入探讨了后向联系但不太广泛的前向联系的构建。该文件建议大规模发展当地产业，以深化后向和前向联系，从而帮助拉动或推动薄弱部门摆脱停滞。
