Production Network Centrality in Connection to Economic Development by the Case of Kazakhstan Statistics

The Nonlinear Model of Intersectoral Linkages of Kazakhstan for Macroeconomic Decision-Making Processes in Sustainable Supply Chain Management

“…This article continues the cycle of our (with co-authors) research [25][26][27][28][29][30] related to the development and application of methods of nonlinear interindustry analysis, taking into account the substitution of production factors.…”

“…Assumptions 1 and 2 guarantee that the Slater condition holds for the optimization problem (1)-( 4) and the set A(l) is bounded, convex and closed for any l ∈ R n ≥0 . Therefore, the limited optimal solution of (1) exists [27].…”

“…. , m we calculate from the system (27). Additionally, it follows from (6) that on the solution of the problem the following equality holds:…”

“…More than half of GDP comes from the service sector (55.4% of GDP, 2019). In [27], we analyzed the modern sectoral structure of the economy of Kazakhstan using the Leontief approach and the nonlinear model of input-output balance with Cobb-Douglas technologies. Based on the calculation of various measures of centrality, the dominant sectors in the economy were identified.…”

“…In paper [27], the model of nonlinear intersectoral balance with Cobb-Douglas production technologies and the traditional linear Leontief's model are used to assess the degree of "centrality" of industries in the modern supply network of Kazakhstan. The comparison of the evaluation possibilities of macroeconomic characteristics for the model with Cobb-Douglas technologies and for the linear Leontief model is represented in [28] using the example of large economies at different stages of economic development.…”
