ABSTRACT
This study measures the technical efficiency score of
the manufacturing sector of the palm oil products-based subsector in Malaysia and
investigates the major determinants that influence efficiency. Based on the
Industrial Manufacturing Survey, this study explores the data from 2000 to 2015
over sixteen years, with a total of eleven subsectors of palm oil
products-based. The first stage of the study is carried out with a data
envelopment analysis (DEA) to calculate the technical efficiency score, which
is considered a dependent variable. The second stage of the study uses a panel
regression model to examine the determinants of efficiency comprise the
variable capital-labour ratio, research and development, information
communication technology, training, and skilled labour. The study findings show
that most of the palm oil products-based subsectors are not operating
efficiently. Skilled
labour that is technical and supervisory, and professional is one of the main
determinants contributing to the efficiency level. The variable capital-labour
ratio though significant, but it harms the efficiency level. The moderating
effects show that skilled technical and supervisory workers relatively affect
the food industry's efficiency larger than the non-food industry. The industry still has a lot of room to
improve efficiency in handling input more efficiently. Moreover, the initiative
includes organisational management, equipped
appropriate technology and related factors that will improve efficiency and
increase productivity and competitiveness.

ABSTRAK
Kajian ini mengukur skor kecekapan teknik industri pembuatan berasaskan produk minyak sawit di Malaysia dan mengkaji penentu penting yang mempengaruhi tahap kecekapan tersebut. Berasaskan data Banci Industri Pembuatan, kajian ini meliputi tempoh enam belas tahun dari 2000 hingga 2015, melibatkan sebelas subsektor pembuatan berasaskan produk minyak sawit. Tahap pertama kajian menggunakan Analisis Penyampulan Data (DEA) bagi mengukur tahap kecekapan teknik. Skor kecekapan digunakan sebagai pemboleh ubah sandaran. Tahap kedua analisis menggunakan model regresi panel mengkaji faktor penentu bagi kecekapan, meliputi pemboleh ubah nisbah modal-buruh, penyelidikan dan pembangunan, teknologi maklumat dan komunikasi, latihan dan tenaga buruh mahir. Keputusan kajian menunjukkan sebahagian besar subsektor pembuatan berasaskan produk minyak sawit tidak beroperasi pada tahap cekap. Tenaga kerja mahir, iaitu teknikal dan penyeliaan dan profesional adalah penentu penting yang menyumbang kepada kecekapan. Pemboleh ubah nisbah modal-buruh walaupun signifikan, namun mempengaruhi tahap kecekapan secara negatif. Keputusan bagi kesan moderasi menunjukkan pekerja mahir teknikal dan penyeliaan secara relatif mempengaruhi tahap kecekapan industri makanan berasaskan produk minyak sawit adalah lebih besar daripada industri bukan makanan. Oleh itu, industri mempunyai potensi besar dalam meningkatkan tahap kecekapan dengan mengguna input dengan lebih efisien. Tambahan lagi, usaha tersebut melibatkan pelbagai aspek termasuk pengurusan organisasi, mengguna teknologi sesuai dan seumpamanya demi meningkatkan kecekapan, produktiviti dan daya saing industri berasaskan produk minyak sawit.
