# Table 5 Variable definitions and descriptive figures

Variable Definition Mean SD
Core versus periphery
Firm total export $$x_{f..} = \sum\nolimits_{p}^{{P_{f} }} {\sum\nolimits_{c}^{{C_{f} }} {x_{fpc} } }$$, where P f and C f is the total number of products (defined by CN codes at 8-digit level) firm f export and the total number of destinations firm f export to
Firm export of product f $$x_{fp.} = \sum\nolimits_{c}^{{C_{f} }} {x_{fpc} }$$
Firm export to destination c $$x_{f.c} = \sum\nolimits_{p}^{{P_{f} }} {x_{fpc} }$$
Relative unimportance of an exported product =(x fp./x f..)−1 168,962 7,721,183
Relative unimportance of an export destination =(x f.c /x f..)−1 168,962 9,841,822
Relative unimportance of an export flow =(x fpc /x f..)−1 1,632,487 4.9e+07
Relative distance to core market $$=\left( {d_{c} /\sum\nolimits_{c}^{{C_{f} }} {(x_{f.c} /x_{f..} )} d_{c} } \right),$$ $${\tilde Y}_{{i},{t-j}}=\left( {Y_{{i},{t-j}}\prod\nolimits_{k}^{j-1} ({1}-{Y_{{i},{t-k}}}) } \right)$$ where d c is the distance to destination c 2.14 2.21
