A ban on palm oil imports by the European Union has become a problematic issue, especially for palm oil producers’ countries. Oil palm has been widely used in many sub-sectors, and any changes in the production side may affect many sectors that use oil palm as an input factor in their productions. This study explores the chain of the oil palm sector on the other sub-sectors in Malaysia by using a value-added multiplier method and network modeling. The study focuses on the specific oil palm sub-sector and oils and fats sub-sector in the Malaysian economic structure based on the Malaysian Input-Output 2015 Table. Network visualization and all the analyses involving network methods were developed and performed using UCINET and GEPHI software. The value-added multiplier results explained that the net value between output multiplier and import multiplier is vital to depict the real impact of net resources used as an input factor in the oils and fats and oil palm sub-sectors. The high-density value level shows that the Malaysian oil palm sector has high connectivity in the economic system. From the network visualization analysis, the oils and fats sub-sector has a high level of integration with other sectors within the network. Meanwhile, the oil palm sub-sector categorized in the periphery structure group has a low level of integration in the input-output network. This is due to the high value-added demand for oil palm in the oils and fats sub-sector in the manufacturing sector. Overall, most of the sub-sectors in Malaysia are highly interconnected due to the high clustering ratio. Therefore, ensuring sufficient oil palm production is vital for sustainable production of other sub-sectors.

马来西亚价值链中油棕业地位的探讨

欧盟禁止棕榈油进口已成为一个问题，特别是对棕榈油生产国而言。油棕已被广泛应用于许多子行业，生产端的任何变化都可能影响到许多将油棕作为生产投入要素的行业。本研究使用增值乘数法和网络建模，探讨了马来西亚其他子行业的油棕行业链。该研究根据 2015 年马来西亚投入产出表，重点关注马来西亚经济结构中的特定油棕子行业和油脂子行业。网络可视化和所有涉及网络方法的分析都是使用 UCINET 和 GEPHI 软件开发和执行的。附加值乘数结果解释说，产出乘数和进口乘数之间的净值对于描绘用作油和脂肪和油棕子行业投入因素的净资源的实际影响至关重要。高密度值水平表明马来西亚油棕部门在经济系统中具有高度连通性。从网络可视化分析，油脂子行业与网络内其他行业的融合度较高。同时，属于外围结构组的油棕子行业在投入产出网络中的整合程度较低。这是由于制造业的油脂子行业对油棕的高附加值需求。总体而言，由于高集群率，马来西亚的大多数子行业都高度相互关联。
