Judul: Keterkaitan spasial perbedaan produktivitas tenaga kerja kabupaten/kota di Pulau Jawa
Abstrak: Using 115 districts/cities at Java Island and 9 sectors on the 2001-2008, this study use Esteban’s shift share analysis to investigate the extent to which the existing interregional disparities in labour productivity can be attributed. The different between labour productivity of districts/cities and Java Island average is regressed on the three shift share components: industrial mix, productivity different, and allocative. However, labour productivity is not only influenced by three shift share components as explanatory variables but also by aspects related to surrounding districts/cities (neighborhood). Therefore, this research employed spatial econometric models, i.e. spatial lag model and spatial error model. We observed significant spatial effect for productivity different and the industrial mix component, productivity different as well as allocative components. The result found that labor productivity disparities across districts/cities in Java Island could be attributed to the industry mix, productivity different and allocative components. Whereas the highest coefficient regression value indicated by industrial mix component. Therefore, policies are needed not only for the transformation of labor from one sector (eg. primary sector) to other sectors (eg. secondary sector). It’s necessary to promote policy emphasis on increasing sectoral labour productivity, for example through empowering labor skills and improving of socioeconomic infrastructure.

Judul: Analisis Konvergensi Produktivitas Tenaga Kerja AntarProvinsi di Indonesia
Abstrak: Each province wants to make the process of sustainable development with their regions autonomy. For 13 years running regional autonomy, there is still disparity in Indonesian. This has resulted in a variety of ways, especially labor productivity. During the analysis period, the average of labor productivity highest at Jakarta amounted to 87,16 million rupiah per person and the lowest at NTT amounted to 5,72 million rupiah per person. The purpose of this study is to map the provinces in Indonesia seen from the growth rate of labor productivity and labor productivity value, analyze the degree of disparity in labor productivity, and to analyze process of labor productivity among provinces in Indonesia shows a convergent or divergent process. The research uses dynamic panel data of 33 provinces from 2005 to 2012. Results from the mapping showed that the change of position of the province in 2005 and 2012. Based on analysis of regional disparity found that the labor productivity gap between provinces in Indonesia fluctuating from year to year and tends to decrease. Based on data processing using the SYSGMM obtained that the process of convergence in labor productivity occurred in Indonesia.
